Hi,
First off if this is answered I am sorry.
I did a lot of searching and was unable to see the answer to this...
I am running CM7.1 off uSD. Install went well, and have no issues. That being said, I am unable to find out where on the card to sideload books. I have booted into CM7.1, turned on USB storage, and have 2 drives appear in win: MYNOOK and CM7 SDCARD. I used the size agnostic image, and it appears that there is only the single partition on the card, and in file explorer, it shows the correct card size for memory, but only the single partition.
The only folders appearing on the card are:
.android_secure
Android
LOST.DIR
I tried to manually copy the books, media, etc. folders into a My Files folder on this drive, without success.
There is no other partition to repartition (shouldn't have to do that with size agnostic?). I have no problem loading books into the MYNOOK book folder, which I assume is the internal device memory.
Here is my question. How/where do I sideload books to use the storage on the uSD card? Do I have to create the folders somewhere? If so where?
My goal is to utilize the storage available on the card, but be able to read the titles in the stock software. Is it possible to do this without rooting, or do I need to root for any reason to access the right folders on the card for storage?
THANK YOU ALL!!

In what way was it not successful? Did the files copy and just can't find them with a reader? If so which reader?
The book I transferred over was not found in the stock software when I opened my library. Is there somewhere specific I am supposed to place it on the card for the Nook to see it? Thanks!
For the stock reader, I think you must use the 1gb area of the internal memory drive, which shows up as a separate drive on your PC when you plug it into the computer. When you are in CM7 and connect to the pc, cancel when it tries to install a device for the NC. Check the notifications on the NC, you need to click a button to enable copying files from your pc, and take care to properly safely remove/eject before disabling that and disconnecting the cable from your pc. Better to get a separate reader and install it from the market (e.g., Cool Reader). You can also install the Nook app from the market, but then books need to go within (possibly in a specific subdir) of the "Nook" folder on SDCARD.
So there is no way to use the card memory to store books if I want to use the stock reader??
Should there have been a "NOOK" folder created on the SD card as part of the CM7 process? Is that a file that the user needs to create? If so, does it go in the same partition as the CM7, as that is the only partition my machine is able to see?
thanks again
Hopefully you'll get more input on this, but I think the point of keeping the Nook stock available (aside from not voiding your warranty) relates to use of B&N books. However you can eject your CM sd card and use another sd card if you want more space for user media for use with the stock app. I thought the media drive was the 1gb area, but now I'm not so sure because on mine the MYNOOK disk is much smaller.
When you are in the stock firmware... you are seeing the boot partition of the uSD...
You can write the boot partition... resize it... then run the installer...
I have done it in the past... set up a 2GB boot partition... then setup the ROM on uSD. You then have a 2GB partition you can use when in stock.
Thanks for the info. I am a bit confused by your suggestion, can you please offer a bit more?
By writing the boot partition, then resizing it, does that mean I can resize now, after I have already set everything up? If so, what do you mean by the installer? Or do you mean I have to wipe the card and start over? If that is the case (start over) do you mean wipe the card, create a small partition for the boot to install on? Would that requre the use of an image that is not size agnostic?
Either way, how do I get the file structure in place on the non boot partition for the nook to see files that are saved there?
Thanks again for any help you can provide!
I have never had luck resizing it after it has been booted in the Nook and all the partitions created...
I have written the size agnostic image to the card... resized the only partition created at that point... then put the ROM on it and booted it in the nook so the installer script (size agnostic recovery) can do the partitioning and install the ROM.
For the question of getting the file structure... I'd have to ask how you wrote the files on the uSD... were you CM or stock?
I had always planned on running cm from the card, so when I wrote the files to the card, I was stock.
If I follow what you are saying, then steps for me to try at this point would be:
1. Reformat card
2. Write the disk image to the card
3. Shrink the single partition on the card (where the image is)
4. Add the CM ROM to same partition as the image
5. Install card and boot device
If this sounds right, I have 2 questions.
What size should the partition be for the image and CM ROM, maybe 2GB?
Will the Nook "see" the non-CM partition and create the file structure for saving files on the 2nd partition at some point? In my searches I saw that in early versions, there was a requirement that the 4th partition on the card be expanded to use for storage, won't I only have 2 at this point?
Thanks again so much for the help!
When you write the image to the card... it will only be about 114 MB.... you will probably want to increase the size to avoid any possible size issues later (with ROM's getting larger)
If you plan to use the stock nook ROM as well as CM7... you will probably want 2 GB boot partition... otherwise if you plan to only run CM7 you probably only want about 250 MB.
You can modify vold.fstab on the stock ROM to use partition 4 of the SD for its SD use... then you could avoid the 2 GB boot partition.
What happens when you use VG's SASD... the boot image is about 114 MB... when you boot it in the nook it creates partitions 2, 3 and 4... 2 and 3 are ext3 partitions, partition 4 is fat... partition 4 is the one set for sdcard in the ROM booted from SD...
This is why you can modify stock vold.fstab to point to partition 4... then both ROM's will be putting stuff on the same partition for "SD Card"
I think I follow that, but my issue is that currently I am unable to see partition 2,3 or 4 which I think is part of my problem.
When I set up the card, I used the SASD method, and all I can see in both win explorer and partition software is the single partition on the card. Should there also be partitions 2,3, and 4? Do I have to do something to make those partitions viewable?
I am not comfortable enough with my skill level to attempt to modify the stock vold.fstab file on the device, and was hopeful that by properly setting up the card, I would be able to keep stock as is, and use the card to multipurpose, ie run cm7 on part and use the remaining space on card to store books to be read in stock firmware. I am still hoping to do that....thanks
As far as only seeing partition 1.... that is a limitation of Windows.
By following the advice pertaining to starting over and increasing the size of the Boot partition immediately after writing the image... before doing anything else... you can provide more space for the stock ROM to use on the SD... it will use partiton 1 (the boot partition) without the other modifications to vold.fstab
ok, confused again
If I start over, write image, then resize that partition with the image, am I going to use the "rest" of the card, NOT in that partition to use with storage? OR am I going to resize the partition with the image to be big enough to use as the partition to put books on?
If it is the former, don't I again run into the problem of how to find the other partitions, or will I create them when resize the first partition after writing the image?
Thank you!
You will only ever see the first partition of the sd card when booting from the stock OS. Also with the card inserted in a usb flash card reader on Windows you can only mount the first partition as a drive letter. But you can see and resize partitions with contiguous unallocated space using MiniTools Partition Wizard.
OK thats good to know. Do you know if the SASD install should have created other partitions when I installed to the card? The reason I ask is that even in Partition Wizard, I am still only able to see the 1 large partition with everything in it.
If I start over again, will I need to use the wizard to create partitions first, then write the image to the resized 2 GB first partition, or should I write image to card, resize the first partition? If the latter, will resizing the first partition autmatically force the other partitions to be seen? I am not sure of this option, as I can't see where in the process the other partitions are created? Is this part of the process when CM7 boots?
Thanks!
Write the image. Safely remove from pc. Reinsert to pc. Use minitool partition to resize the (only, at that point) partition to the size you want. Use Apply in minitool software. Quit minitool and resume with the card setup.
does the minitool at that point (resizing) create the other partitions, or will the card setup do that? Do I have to do anything else to the other partitions to make them visable to the stock nook so that they can be used to access books while in stock os?
The card setup will create the other partitions. The stock os is never going to see anything but the 1st partition. You would need a terminal emulator or rooted file explorer installed in the stock os in order to mount another partition.
If that is the case, that stock os will never see anything other than the 1st partition, then there really is no way to accomplish what I am trying to do, correct?
In other words, put CM7 on the card, then when I want to use stock, boot into stock and have the reader find books saved on the card?

Hello,
As the title says, I'm a new CM7 user (running verygreen's SDcard installer, using the 1.3 generic image, with nightly 87, no OC). This is running beautifully, except for one thing... I didn't use a big enough SDcard to start with and now I'm faced with looking for the right way to migrate to a larger card (or alternatively to make use of the NC's built-in eMMC in some fashion to augment the current SDcard).
Can someone tell me if the following approach will work? And is it the right/best way?
1. Use Win32Imager to make a full disk image of the current card (4GB).
2. Write the image to a new 8GB or 16GB card. At this point I should have a perfect copy except that there'll be wasted space on the card past the final partition.
3. Boot into a Linux recovery type LiveCD and use gparted to expand the final partition to use up the rest of the space.
4. Am I done? (crosses fingers?)
The goal of this move is to give myself some room to drop movies, music, etc. onto the /mnt/sdcard partition (which I believe is called /media by NC Stock 1.2?) Will what I described work?
Thanks in advance,
fuul4nook
P.S. One extra question, will the fact that my NC is a blue dot cause any problems with the idea? And if not, is there any way I can use the eMMC partitions while running CM7 from SDcard?

You should be able to do what you want but use Easeus Partition Manager to extend the 4th partition on the SD to get full use of the card. I don't know what you mean by "blue dot", but you can access 5 gb on the emmc directly through apps if it's music or video. You can also use File Expert or Root Explorer to store what you want on the emmc partition, which will then also be available when you boot into the stock NC rom.

Resize partitions
1. Download Gparted LiveCD
2. Extract onto FAT / FAT32 USB memory stick or burn to CD-ROM
3. If on a USB memory stick, run \utils\win32\makeboot.bat from the memory stick.
Do NOT run makeboot from a hard disk!
4. Boot computer from USB device into Gparted
5. Connect your Nook running Noogie of a Micro USB card (this will make the partitions visible to Gparted).
6. Resize the last partition (nr 8) labelled "data" (= Barnes & Nobles content)
Make sure to move the partition to the far right.
7. Move the next-to-last partition (nr 7) labelled "cache" without resizing it.
8. Extend the next-to-next-to-last partition (nr 6) labelled "nook" (Side loaded content) to fill the gap.
9. Remove USB cord, Micro USB card and boot your Nook.
10. In Settings you can inspect the amount of storage space.
I received errors when the partitions were about to be moved on the disk.
I changed the partitioning resize to field where it says "Align to:" from "MiB" to "Cylinder". After a 2nd attempt and doing each partition individually all worked out well.
For those only with Windows, download Gparted LiveCD iso image and use virtualbox to boot from it. It still worked well.
Edit: I successfully repartitioned two of my Nook Simple Touch using the method above + virtualbox + Gparted LiveCD iso.
Surprisingly, the size of partitions in my two NST were slightly different, suggesting that the physical size and location of partitions don't matter as long as their order and type in the partition table are as expected and the size is big enough to hold files there. I resized and moved the last three partitions as I wanted several times and made sure they work well.
Factory reset, upgrade to 1.2.1 (this seems to require the cache partition to be big enough to hold the firmware update file: something like 128MB worked for me), rooting all worked well with resized partitions. I ended up shrinking the cache partition down to 32MB and the data partition to 128MB, reserving 1.11GB for the side-loaded contents. I'm sure the system partition can also be shrunken, but I didn't go that far.
Why a live cd? Does installing gparted to whatever linux flavor you're using not work?
I don't use linux on my PC... only on hacked router & nas.

So dump Noogie on a microsd card run noogie and while noogie's running plug nook into pc? Do you just plutg it in and it does everything auto, or does something in noogie need to be run? Does this work on a nook touch glow?
Sorry to sound so dense but rooted using NookManager.
Edit more to the point it's throwing up an error when trying to move sdb8 around. It shrank fine just won't move. Not sure why. Not getting any useful error messages. Just 'can't have overlapping partitions.'
Odd. I was able to move it twice and get it to behave. Yet do the same n one move and Nothing. Apologies for the rinning Log just. Meh. The rest of the partitions resized in one step. sdb8 was the one that needed two steps.
Aaaand Success. Showing up as having 913MB free as opposed to like 212 or whatever.
Edit: now I'm getting a constant 'low space' warning from nook (understandable.) And installing apps is hit/miss on if they'll actually install. Keeps claiming space issues.
Query. Do apps install to the BnN partition or where?
Good to hear another success story. In my case I squeezed all the way to 1.45GB for the side-loaded contents. boot/rom/system/cache/data partitions are shrunken, and factory partition is busted. I had to use fdisk instead of GPartED to completely recreate the partition table, though.
I think, apps are installed to the data partition (the 8th one) under /data/app. Before being installed it's downloaded to cache partition (the 7th one). In my case I gave 16M for cache and 128M for data. If you are low on the data partition and have some space left on the system partition, you can move apps from /data/app to /system/app.

.c0.'s original post.
His instructions describe how to use gparted to resize the partitions on the NST to make full use of the memory available after you have rooted it. I've used gparted before so maybe they were clearer to me than to others but the thread title was the main clue.

I kind of thought that Nook's internal 2GB flash is already sanely formatted (i.e. most space is dedicated to the partition that is mounted at /media). If that is not the case, then that should be noted in the first post. It would also be cool if it said exactly how much space each partition has (I think i saw these partitions back when i've used Noogie to make initial backup of my device, but i don't remember the details), and how much space you would gain, and on which partition (and where it is mounted).

How to maximize RAM available for apps
I found this easy to read table here.
I doubt that I will ever download books from B&N. I want to minimize the space for that. I infer that I should minimize partition 8 that gets mounted to \data. Is there a practical / actual minimum for this?
I see that anything I copy in from my PC over USB is going into media. 100MB should be more than I need. I could put in an SD card for this sort of thing if it grows.
My question is, which partition do I want to increase to make the maximum available to apps downloaded from the google marketplace?
If an application requires a minimum of 512 MB of RAM, which partition(s) do I need to set >= 512?
New additional question: Upon some further research, I see that you can use sd cards for swapfiles to increase system RAM up to a maximum of 4GB. Does anyone know if it is possible to use this built-in storage for the same purpose?

I have a little (maybe big?) problem. Can't partition with Gparted Live, as gparted scans my /dev/sdb (nook) infinitely. If I plug out my nook, other partitions (in my case: /dev/sda) become visible and ready. Looks like my nook hangs gparted. Tried on 2 different PCs and no effect. Tried different version of Gparted Live (i486 & amd64) - still nothing.
Of course noogie is inside the nook unit, ready and steady. Already made a backup of (non-rooted) device, plus partitions are visible in Minitool Partition Wizard on Windows 7.
What to do in this situation? Is Linux the only safe way to repartition device? Or maybe Minitool would be as effective and safe?
If Linux is the only way to go, how to make nook visible to Gparted?
Please, experts.

If Gparted doesn't work for you, I'd highly recommend Minitool Partiton Wizard - it's what I used to partiton my Nook. Nice, easy UI, too.
Yeah, I often work with Minitool, but is it as safe as Gparted when it comes to nook?

What to do
Explain to me, please
I have a question that is more android-in-general than Nook specific. I am trying this out on my Nook first, as it is an unbrickable device, before tinkering with my target device (a phone). My phone also does not have Clockworkmod recovery support, so a bricked device would be fatal.
I am attempting to increase the memory available for installed apps. My phone has limited space, but a bunch of pre-installed junk that I thought I might be able to get rid of in order to make more space for more apps. Knowing that simply deleting these pre-installed apps from the /system folder does really nothing, I set about making and editing an image file from the /system partition, then reflashing this image back to phone. As I am trying this on the Nook first, here is what I did:
1. Adb into the Nook and dd the system partition to a system.img file on the sd card.
2. Copy the system.img file to my desktop and mount the image.
3. Edit the image, removing the LiveWallpapers.apk file (a hefty ~3M file), then save the result back out as a new system.img.
4. Copy the new system.img to the sd card, then adb back into the Nook and dd the system.img from the sd card back to the system partition.
Everything appeared to work fine. The Nook boots, runs fine, and the LiveWallpapers.apk file is nowhere to be seen. Problem is, there is no difference in the available memory on the device.
In retrospect, I suppose I should not have expected there to be a difference. I am under the impression that the system partition is a read-only partition, and that extra space on this partition is not available for installation of apps. I am guessing that in order to increase the memory available, I would need to resize the data partition.
So, ultimately, my question is whether or not this is correct. Do I need to resize the data partition in order to actually get more memory available for apps, or is there an easier way? If I would need to resize the partition, how would I go about doing this, and would I need to take this extra space away from the system partition (the extra memory would need to come from somewhere, I imagine). I would envision removing bloatware from the system partition, shrinking that partition as I would no longer need that much space, and giving that extra memory to the data partition. Bear in mind that I need to do all of this through adb as I will not have Clockworkmod recovery on my target device.
Alternatively, I could be out my gourd and none of this makes any sense. Feel free to let me know if this is the case.
Thanks!
You've got it right.
The Nook emmc has partitions for boot, rom, system, data, and media. Originally data was 1g and media (/emmc under CM7) was 5g, newer models have reversed this. Data is where apps and their data go.
There are threads here about repartitioning newer Nooks with lots of good discussion. It sounds like you are capable (or want to be capable) of creating a custom partition scheme; there's enough info there for you to do that.
Experimenting with an 8g SD card might be a good place to get familiar with the tools. The "size-agnostic" installer will use a pre-partitioned SD if it finds one IIRC.
Good luck!

I just wanted to re-iterate the importance of what you said here.
I have sent several people off to buy Nook Colors who were interested in developing for android, for this very reason.
Nothing else you can get your hands on ( to my knowledge ) is as safe of a dev-tool as the Nook Color, because of the first boot to sd-card.
It doesn't matter what you do to it, at the end of the day you'll have a working device unless you throw it down the stairs or something.
Bonus points for running an sd-install directly, because when you hose it you just reflash a new microsd card.
Can't reformat the card because windows only reads the boot partition? No problem - if you still have your Nook Color with it's stock software just boot it up and pop the microsd card in. The B & N software in the Nook Color will just format the card, without a care in the world for any existing partition schemes or whatnot.
You're on the right track for what you're trying to do, as the previous poster has pointed out, so just wanted to give you another vote of confidence letting you know you're doing all the right things for all the right reasons.
Thanks for the replies!
You know, I actually did the repartition of my Nook using the CWR zip file. I hadn't thought to go look through the original thread for the manual instructions. As you pointed out, I found the directions here:
http://forum.xda-developers.com/showpost.php?p=13971291&postcount=110
The only problem is that his instructions require that you boot from the SD card in order to manipulate your interal memory. This is fine and good on the Nook, but not possible with my phone. Any idea what would happen if I tried to repartition the internal memory while booting from the internal memory? Seems that this would not be possible....or at least wrought with peril. I think that my phone can boot into a fastboot mode, but have not tried that...anyone know if this would help?
Perhaps I am just playing with fire here and need to settle for cramped memory space on my phone. I am just too accustomed to my 5GB of available app space on my Nook.
Thanks again.
Well, after some more Googling, I think I might abandon the repartitioning bit. I think I am likely to brick my phone, even though I think I could do it manually on the Nook. In addition, it appears that many phones are set up so that the kernel resets the internal memory partitioning on boot....so I might also need to mess with the kernel to get this to stick. This is beyond my skill set and really not worth my turning my phone into a paperweight.
I thought of a bit of a workaround, however. As I can extract and edit the image of the system partition, I will simply install the apps that I will eventually want on my phone on my Nook instead, extract the apk's from the Nook, then insert them into the system image file from my phone. Reflashing the system image then puts these apps into the system partition instead of the data partition, effectively saving me hoards of space on my data partition. A bit laborious, but for several core apps that I know I will want and that are memory hogs, I think it will be worth it.
Anyone see any problem with this approach?
Hello,
Complete noob here and I am not ashamed to admit it. I did create a bootable sd card with CM7 stable on it and the card is partitioned into 4 spaces. The boot space only has a capacity of 117.63 MB, while the 4th partition named CM7 SDCARD has a whopping 28.21GB available.... 112.14MB used..... Im guessing for application. Anyways, I am trying to put books and videos on my NC and there is not enough space that is accessible. Any way to make that boot partition spave larger? Maybe move some of the extra space from the 4th partition? I have EASEUS Partition Master but I have been unable to get it to work..... Any help is greatly appreciated.
I did search for a post like this but did not find any answers which I understood.
Thanks in advance,
What is it that you are trying to do?

I am trying to put books on my sdcard that I downloaded on my computer for school. When I copy to the directory boot/myfiles/books it says that there is not enough space. So I want to enlarge the size of the boot partition
After you burn the partition image using Win32Image, the size of the boot partition is roughly 117mb. At this point use EASEUS partition to expand the boot partition to the size you want. In my 32gb SD card, I created a 16gb partition. Then I copied CM7.1 and Gapps to the partition, booted NC and CM7.1 was set up in the remaining space, with /data at 5gb and /media at 9gb.
Would you then access the files while booting from the SDcard or internal memory (eMMC)?
If you want to see them when booting from SDcard, don't put them on /boot as you have found out there is not much room. You want them on partition 4. Remember that Windows will not mount partition 4 without some heroic efforts. I use either NookColor UMS (free, see here) or WiFi Explorer Pro (paid, check either Android or Amazon Market).
If you want to see them when booting from eMMC, that is slightly more advanced. You don't have to root, but there is a file on the system on eMMC that needs to be edited to mount partition 4 rather than partition 1. It would take some time to search for it, but someone posted a guide a while back. Search for something like sharing SDcard and/or editing vold.

Ok...... So I got the boot partition resized to around 20gb and I have copied the books from my hd to the sd card E:\My Files\Books...... Problem is I now cannot acess them when I boot CM7..... Any fix to this or will I have to boot from the eMMC?
Ok....
You're making the easy stuff hard...
You want a large partition that is accessible by CM7 running off the SD and your windows PC. Like Homer said, it is nigh impossible to get windows to mount secondary partitions off of an SD card reader. What he forgot is that CM7 allows you to access partitions 3 and 4 over USB. CM7 can access the boot partition but most apps won't look there and it won't be accessible over USB.
I would recommend that you restart from scratch. Allow verygreens installer to set up the default partitions. Plug your device into your PC and transfer your pdfs to partition 4 that-a-ways. That way you won't have to remove the sd card anytime you want to access your pdf folder.
Even when you plug the CM7 booted NC into your PC, you still need to mount the /sdcard partition to Windows. I find it is easiest to use NookColorUMS on the NC to mount that partition, see above. Otherwise, when you plug into the Windows machine you only get /boot mounted.

Hmm, when I plugged a nook running CM7 from SD card, I get access to /media and /sdcard. I had to move the gapps.zip from /sdcard to /boot manually using a file explorer.
I'm offering an apology to gall and Homer first so pls don't jump on me.
You guys harden a simple issue and confusing the OP.
To OP,
I assume you got a 32GB uSD card, using verygreen's image. You got 117MB on boot.
LEAVE the boot partition ALONE. The only thing you should put there are the ROM (CM7 zip file) and the GApp zip file. NOTHING ELSE. Your music/ebook/video, etc. should NEVER go there. You will place them in the left-over storage created by CM7, normally called CM7SDCARD.
How do you access CM7SDCARD so that you can transfer files over?
The only way is
+ NC on
+ connecting NC to PC (windows)
+ look at the NC notification bar, usb icon should be displayed
+ tap on it, enable usb mass storage (connect to PC for file transferring....)
+ Windows PC should by now recognized the CM7SDCARD and ready for use.
That's the ONLY WAY and the correct way.
If you use that bootable CM7 uSD and plug directly into PC, you only see the boot partition which only 117MB. Again, the boot partition is NOT meant for personal stuff.
What may confuse some people is that when they plug the device into PC then it does not by default auto-mount so you don't get a drive in the PC until you use the USB notification and turn on USB storage.
For non-techie users I normally install the automount USB app from JRTStudio so the drive pops up straight away on the PC and there is no confusion over this point.
The other good reason for using the USB (or alternatively wireless connections like ES File Explorer) is that it reduces taking the SD card in and out and any risk of damaging the socket.
My apologies, I never checked out the USB notification. I sort of ignored it. It seems a handy implementation of the basic functionality of NooKColorUMS.
What is MyNOOKColor though? CM7 SDcard is the one I typically use. Nevermind: it is the eMMC. I never bothered with that one since going to SDcard boot.

This question probably belongs in the thread "[ROMS]NEW! Dualboot Mirage CM7 / ICS CM9 Image for SDcard [3/26]", except that I can't post there yet.
I was able to create a working dual boot card per the instructions. However, I could not make a working card that made use of all 16 GB of my card, rather than just the <4GB size of the image file. The card still worked when I used fdisk on my Mac to increase the size of the last, 'sdcard', partition to fill up the available space. However, that did not increase the capacity of the FAT volume in that partition, leaving the extra space still unavailable.
After saving the files from that volume, I then used the Mac's Disk Utility to erase the partition and re-create it as a FAT partition using all the available space. Once I did that, unfortunately, the Nook would then not recognize anything on the SD card and would only boot into the Nook's own ROM.
As an alternative, I tried leaving the existing partitions alone and editing the MBR with fdisk to create a new partition using the available space, which I then formatted as a FAT partition with Disk Utility. Again, the Nook would no longer recognize the SD card and would only boot into its stock ROM.
I actually tried the above with two 16GB SD cards, a SanDisk Class 4 and a Samsung Class 10, and with two Nooks. Moreover, I tried a number of manipulations of the MBR, mostly to make it identical to the original one except for necessary size changes. Nothing worked to get a card that would boot and use the full 16 GB. I'll admit I haven't tried everything, such as trying to resize to something less than the full 16GB, but I've put so much time into this already that I don't want to do any more until I get some feedback.

Well you're missing just one step after fdisk. If Disk Utility is failing at it you could try terminal:
First you need to find out where your /sdcard is being mounted at. Use "diskutil list" to find out
Once you find out where it's being mounted (eg. /dev/disk4s7). You will then need to unmount the volumes before you can format it.
Code:
$ diskutil unmountDisk /dev/disk4s*
$ diskutil partitionDisk "/dev/disk*" 1 MBRFormat "MS-DOS FAT32" "sdcard" "*M"
Replace * with the actual values needed. You might need "sudo" to perform the format command. Make sure you're formatting the correct mount point or else you might end up wiping your system. But if you were able to use fdisk, I'm sure you have a good understanding of terminal.
Haven't tried it myself. But it should(might) work.

Won't "diskutil partitionDisk ..." wipe out all volumes on disk?

When I type
Code:
diskutil partitionDisk
in Terminal to get usage info, I see, inter alia, the following:
Code:
(Re)Partition an existing disk. All volumes on this disk will be destroyed.
But that is clearly not what I want to do. Am I missing something?
Updated update:
I have tried, several times and on both SD cards and both Nooks, diskutil eraseVolume, a presumably more powerful version of the erase option in Disk Utility. I tried one or another of the commands:
Code:
diskutil eraseVolume MS-DOS sdcard /dev/disk4s7
diskutil eraseVolume 'MS-DOS FAT32' sdcard /dev/disk4s7
on cards that were booting, but with the small sdcard partition or the small volume on the enlarged partition. I also tried at least one of those commands on a card that was already not working after modification. In all cases, the commands ran without error but produced a non-booting card. Changing the 'ob' partition id back to 'oc' with fdisk didn't help, nor did any restoration of the original fdisk MBR info.
In sum, the only change that I have been able to make to a card as originally written from the image without making it unbootable was to enlarge the sdcard partition while leaving the sdcard volume untouched, and therefore not using most of the capacity of the partition.
Some more general but related questions.
Since I've got your attention, Racks, let me ask a few questions whose answers might help me and others understand what is going on here and what might go wrong with this and other Nook Color boot setups. Of course, also please point out where anything I think I know is, in fact, wrong.
1) I understand that the firmware boot code on the Nook first looks for something on an inserted SD card to boot from. It seems it looks for a file named u-boot.bin on the first partition of the inserted card to which to transfer control. Does it also check other things on the card before transferring control to u-boot.bin? Does it look at the file MLO? Does it look at the partition labeled sdcard, or at any other partition, before doing so?
2) Presuming that it does transfer control to u-boot.bin, what does the latter check before either booting from the (default) ROM on the card or, if the Home button is being held down, going to the interactive boot dialogue? My experience has been that, when using one of my 'non-working' cards, the Nook goes quickly to the ROM on internal memory without showing any visible signs of doing anything else first. In other words, it 'knows' that it can't boot from a ROM on the sdcard before actually trying to do so.
