[Q] In simple terms, how to access/use storage on CM7 SD

I have spent the last week reading and searching the forums in an attempt to find out how to be able to access and use the empty space left on a CM7 boot sd. Some of the posts were confusing and others seemed to be targeted to those who are already very familiar with the file structures of these systems. The only paritioning experience I have is dividing a boot drive before putting on XP. I am using a Sandisk 8gb and it looks like there is about 5 gig free. Win XP is the os I am running.
So the questions I have are:
1) In simple terms, exactly what has to be done to a boot CM7 SD card to be able to use the empty space for books, mp3, etc? On the recommendations I read in different threads, I downloaded easus partition master, gnome partition editor, and minitool partition wizard. They all pretty much do the same of being able to display the 4 partitions, but what do with the programs then?
In the near future I would like to get a 16g or 32g and wouldn't want all of that space going to waste.
2) Is it possible to have it so that the NC stock boot can read the books downloaded in CM7? I have not been able to find where CM7 stores books.
Thanks to all whose work helped me get to this point. The NC is a fascinating piece of hardware.

Hey! Using the remaining storage on your SD card is quite easy. Just download and install this program on your NC. http://forum.xda-developers.com/showthread.php?t=952456 open the program and select the 4th partition to be mounted. Now when you plug your nook into the PC, the partition which holds media etc. Will be mounted you can now transfer mp3's, roms for Emulators etc.
As for #2, Your cm7 books should be on the previously mentioned partition, which is the 4th.

5G sounds about right for the /sdcard partition. The rest of the partitions on an 8G card are /boot, /system, and /data. Use Root Explorer to poke around; you can tell when you jump partitions because the used/free numbers at the top will change.
/boot is not normally mounted.
The root filesystem is in-memory and is initialized from /boot/uRamdisk by default.

The original instructions in the size-agnostic install thread detail what happens to various sizes of card; for anything above 2G /sdcard gets all the extra.
Any apps that use /sdcard for storage will use this space. App-specific config data and small databases are generally in /data unless instructed otherwise (I'm using less than 300M of my /data partition as yet). The app info or permissions will often give clues; if the permission for "read and write SD card" is requested or required, the app can or must use this space. Some apps (like BeyondPod) will always use /sdcard.
So, your space isn't wasted, it's just unused until you fill it.
2) Is it possible to have it so that the NC stock boot can read the books downloaded in CM7? I have not been able to find where CM7 stores books.

The CM7 SD boot cleverly uses the built-in memory for both /cache and (at least some) media storage; the "media" stock partition pre-1.2 is mounted as /emmc; I don't know how the SD boot uses the newer partitions. The NC app stores books in "/emmc/B&N Downloads/Books" and magazines in ".../Magazines". You can move your music files to "/emmc/My Files/Music" and the stock music player will automagically find them there, freeing up even more space in your SD. This partition is mounted the same for emmc-booted NCs, making an easier transition if you get to that point (it took me months to decide to go ahead and do it, and I'm happy with the choice). Other apps may look there, or can be told to look there, but since it's a new-ish Android "feature" (convention, really), it's not universal.
When you use USB mounting by plugging your charger cable into your PC's USB socket, by default the two "drives" mounted are /sdcard (named "CM7 SDCARD") and /emmc ("MyNookColor"), so you can use your PC to explore, backup, and move files back & forth to experiment. Both partitions are FAT32, so all PCs should be able to handle them. Remember to tell the PC to unmount them in software before unplugging the cable, like any thumb drive.

It is, isn't it? I haven't regretted buying one for a minute.

Thank you for posting the reply on the APP nook/cm7 file system.
Unfortunately, it still doesn't address HOW to sideload (DRAG AND DROP) books on the utilizing the empty portion of a CM7 SD card.
1. I put the SD card into an reader.
2. Windows xp detects the card.
3. I pull up windows explorer.
4. It only displays the "root" directory. Yes, I can drag and drop into the "my documents" folder but this partition only contains about 300 meg total storage.
5. It does not display the other partitions, thus I cannot drag and drop anything into the 5g partition.
Yes, I can drag and drop on the NC onboard storage, but not the CM7 SD card. Is the remaining 5 gigs only allocated for APP storage?
Now after 2 weeks searching this site and seeing numerous recommendations for software but not what to do with it or cryptic posts assuming that one already is very familiar with the android os, I am pulling my hair out over this. The only post I found that directly and simply addressed the issue requires that I reformat the SD with SDformatter to allow for full storage access but then I have install CM7 all over again.
I downloaded NookColorUMS-0.3b.apk using Opera, but that is all it did. I had to search again and it mentioned something about ADB (no idea what that is) which had to be installed. Aparently that doesn't work alone and it lead to another link to more required software - the Android SDK and then came a long list of more steps just to install that.
Hopefully, if I ever figure this out, I will write a simple to understand post that new NC CM7 people like me can understand.

Try this: unplug the charger cable from the "n"-shaped brick. Plug the cable into a USB port on your computer. Plug the other end into the NC as usual.
Tap the button(s) that pop up on the NC to allow USB mounting.
Two new drives show up on the PC. These are /emmc and /sdcard, but they'll have different names on the PC. Use Windoze Explorer to drag and drop. I might suggest /sdcard/download as a first try, but feel free to drop copies in multiple directories in order to experiment. Adobe Reader looks all over for its docs.
When you're done, click on the PC tray thing to release BOTH drives from the PC.
Poke around with your reader to find these files. Some readers might be better at looking around than others.
Let us know how you get along!

So once you download the NookColorUMS.apk, use the file explorer on your nook, go to the 'download' folder and click on this file. It will open up and ask you if you can install the program. Click yes and let it install.
When you are done with that, open the program and mount the partition of interest(i think its 4 as a previous poster stated). Now when you plug your nook into your computer that partition will mount. There should be 4 partitions if you are using the CM7 on SD card.
You should be able to now drag and drop files on that partition. Just make sure you unmount properly as I have run into problems if you just unplug it.

I am using Racks Phiremod/Honeycomb dual boot image but I don't see why this method would not work for your install. Rather than messing with mounting partitions and all that whenever I want to put something on the SD Card partition I will just plug my nook into the computer, copy and paste whatever file I need onto the nook's internal memory, and then use root explorer to cut and paste the file from the internal memory to the SD Card partition.

my emmc and sd card both show up and writable drives. I use stuff that I need faster access to in there, since the mount time is faster than the SD card.

Overwrote Stock with CM 7.1, want to load books into internal memory for Nook App

This is my first Nook Color-> android flash. I'm having trouble loading my books back onto my Nook.
I followed a how to from android forums, setting up a 2GB uSD card to install CM7.1 using CWR:
I downloaded the rom from CM: update-cm-7.1.0-encore-signed.zip
(I cannot share the link since i just joined, but if you google: "nook color cm7 storage" and click the first link, that's the process I followed)
Installation went fine, I also added the google apps package, and can finally download apps from the general android market rather than the B&N market. I downloaded the nook app so I can load my books back on (mostly epub format). The problem is that when I run the Nook app, it says I have no SD card inserted. This is true, but I didn't need one to load books into my additional storage on the Stock Nook rom. I also have lost the USB storage mode ability I had on the stock rom.
If I go to Settings->Storage I have the following partitions:
1)Internal storage: 0.792/0.92GB
2)Additional Storage: 4.82/5.00GB
this is the /mnt/emmc drive
3)Additional Storage: unavailable
this is the /mnt/usbdisk
Again, all I'm looking to do is load books into my internal storage like I had with the original Nook Rom, and I'd like to be able to drag and drop them from my computer via USB. Any suggestions would be greatly appreciated.
If it's too complicated I may go back to the stock rom, I just wanted the option of using a better web browser and having access to more apps with full android.

on a side note, in win XP file explorer, I see two drives when my nook is connected to USB, but neither has any data, and simply tells me to insert a drive/card when I click on them

Problem Solved
I messed around a bit and finally got things working. I wasn't getting USB mode, because you need to open the tray and click on USB Connected, then you get the "Turn on USB storage" dialogue. Yes, I'm a CM7 newbie. My stock nook, and stock Nexus One do not require this step. I also went into settings->CyanogenMod->Applications and checked the "Use internal storage" box, which switches your internal and SD card names in the system (requires a reboot). I'm not sure if this last step is necessary.
As for sideloading books to read, you have to figure out where your reader app wants to have them located on your device. For the Nook app, you put them in the "Nook/MyDocuments" folder. It could not find my ePub books unless I put them there. Then they still don't show up at the normal library page, I have to go to "My Files" in the drop down menu. On a side note, I'm liking the Nook app, which has page turn animations (the stock nook reader app does not). When you enter your B&N account, it should automatically sync books you have purchased.
Next thing to try is other reader software. I installed kindle and google books, but all my books are currently ePub. I'm going to try Blio and Aldiko next.
Hope this research helps someone else out moving from Nook Color as an ereader to Nook Color as an android tablet still used as a reader.

I wondered this myself and when I was having issues with the app I uninstalled it, changed the CM7 settings to install all apps internally as to the default of "auto", rebooted and reinstalled the app and then changed the settings back and rebooted. While that fixed my problem, the app still wanted a memory card installed. The reason is this is not a tablet app and it is looking for a card because most (or at least many) phones do not have enough internal memory. Since I used a card for backup, updates, etc this was not a big deal for men.

ive tried moving the book to the MyDocuments file and still am not finding the book i have downloaded.. it is in pdf file format so would this prob be the issue? ive selected the my files icon and it shows (0) files... not for sure what all im still doing wrong to get my book to read on the Nook app

Why aren't you using the setting to use your Emmc partition as your sdcard? It's an option to in CM7.

Bmar08, I'm not sure if the nook app will read PDF files. You can use file manager to find your PDF files, then open them with your browser. I also started using the free Aldiko reader, which will read ePub and PDF files. It has a lot of nice options such as font size, brightness, background color, etc. so you may try that. Aldiko will also let you browse your directories to indicate which ones you want to include in your library!

[Q] Where are Cmod's data files located on a bootable CMOD 10 microSD?

Hello.
I recently followed these (apparently and abridged version of this) instructions to get the Cmod 10 nightlies running on my nook off of a microSD card. My question is this: where are the data files that Cmod (or vanilla Android, for that matter), creates on your SD card? I am trying to figure out how to transfer files from my computer to my nook (as I did with my microSD in the Cmod 7 install running off the internal HDD of my nook), and can't figure it out. Either answering my original question or just giving me a way to transfer my files would be much appreciated.
Thanks,
Sora

Depends on what you mean by data files. There are two kinds. One is where CM stores the installed apps and their settings. I doubt that is what you meant. The second are media data files, like books, magazines, music, movies and just general downloaded files.
If you meant the second kind of data files, for an SD install they are kept on partition 4 of the SD, named SDCARD. You cannot see that partition when you put the SD directly in the PC. The only way to see it with the PC is to plug in the USB cable to the PC while CM10 is running and see them with Windows Explorer. And by default CM10 uses a protocol called MTP to let you see them. It shows up in Windows Explorer as a portable device in the left pane below the drive letters.

[Q] Write (download) to internal storage?

Total noob here. I did the CM 10.1 and gapps (the proper version). All -seems- to work well except it doesn't appear that I can download anything to the internal storage even though there's about 800MB available (according to the Settings).
Example 1: I installed the DropBox app and it tells me I have to use an external SD card. Doesn't seem to be any way around this.
Example 2: I installed an eBook reader named "UB" and, when I ask for it to download the user guide (the link to it appears within the app in my bookshelf), the app advises that I don't have an external SD card (which is true).
I'm wondering if this sort of mod (Android overwriting the stock B&N Nook Color software) means that I can't use the internal storage. Is this normal? If so, I can live with that as a microSD card is cheap and has much more space. I'm just an inquiring mind that wants to know.
If there's some sort of setting that I've missed—remember, this is my first Android device—I'd appreciate a pointer.
By the way, it appears as though the old method of side-loading my non-drm'd epubs isn't available. Is there an app for this? IOW: How would I turn on filesharing or have the device mount when plugged into my Mac or access a shared folder -on- my Mac? (I can enable SMB on my Mac if necessary.) I imagine I can use a microSD and simply use ana adapter to get it mounted on my Mac if all else fails.
Thanks in advance for any assistance.

You need to swap sdcards so that it considers your internal sdcard as your external sdcard. Go to my NC Tips thread linked in my signature and read item A16.

Tried the first suggestion in A16 (adding that one line of code) but, after a power-off / remove card / power-on, UB and Dropbox complain about not having a card.
Frankly, as long as the apps I install go to the internal storage (and they do), I don't mind leaving the SD card in place. An extra 16GB is a good thing.
Next up is finding an app that restores the original "mount as external HD when plugging in to Mac with USB cable" feature that was present in the original NC software.

Rooted Nook STG, issue opening files from SD card.

<SOLVED>
Hello XDA forums,
Before I rooted my Nook Simple Touch with Glowlight, I had no problem sideloading books onto the SD card and opening them from the native Nook Library app. However, after rooting (with which everything seemed to go fine), the following behaviors happen:
I can see sideloaded epub files in the Nook Library on the SD card /My Files/Books directory, but
when I try to open any of them, I get an error that says, "This Nook, cannot read this file. It maybe an unsupported format", however,
if I go through the ReLaunch file manager, it opens fine in the native Reader app, and
if I sideload the same file by usb to the Nook's main memory, it will open fine from the Library, but
if I copy/paste the file from the SD card to the main memory via the ReLaunch file manager, I get the error message.
Puzzling... any thoughts?
Thanks,
Spindle

I am not familiar with Relaunch so was unable to check that angle. I did discover, to my surprise, that neither epubs nor mobis will open in the appropriate app from ES File Explorer! Jpegs and such do, but not those e-book files. So that was weird. I never would open them that way, but it's still unexpected. The " activity picker", or whatever it's called, can be really squirrely. I don't remember where the file is located any more but I once went to investigate it and found multiple instances of file associations, none of which worked...
Does the problem persist through a reboot? Do the epubs that refuse to open from the Library file manager have the little "n" in the lower right corner?

Thanks for the response. Yeah, the problem persists through reboot and indeed those epubs that refuse to open from the Library have the little n like they should. They just do not open

Mmm... I'm sure you've tried this, but what happens if you transfer an epub via USB to the internal storage [file opens correctly in Reader from Library] and then cut/paste it to storage on the SD card? I know that's a pain and should not be needed, but I'm curious.
The only other idea I have is to try a different File Manager and see if transfers via that app give the same results (to test if this is a Relaunch issue, although I'm sure people would be going on about it if it were). I move files around all the time with my old version of ES File Explorer and never see any issues, but then I don't have issues copying to the SD card via USB either.
Mmm...maybe one other idea. I sometimes use Wi-Fi File Transfer to move epubs from my PC to the NST. It's a very simple app with a browser interface (on your PC). I've never experienced any issues with moving files that way--also saves wear and tear on the USB jack. If that gives epub transfers that are unreadable then the issue is deeper than the method of transfer.

Thanks again. I will noodle on those ideas and let you know what was the outcome.

Sooo... I never figured it out and just lived with it. However, this week (a year later), I had to update the Nook STG because there was a mandatory transport layer security update that made it unable to access the B&N store via the Nook without updating. The update wouldn't install on the rooted nook, so I returned the device to factory default then installed the update. I wasn't using any of the rooted capability anyway, other than to open books from the SD card. After successfully installing the update, the nook still would not open books from the SD card in the native nook library. Since, it appeared that the problem had nothing to do with the prior rooting, I figured it might have something to do with the SD card itself. I unmounted and reformatted the SD card via the Nook's built in utility, then reloaded my books. Viola!! The Nook recognizes and opens the books from the SD card now. It was apparently an incompatible card format or something... So, SOLVED.
