Hello, I new to the Nook Color. I just ordered a couple for the kids for X-Mas. I'm no stranger to rooting etc. As I understand it CM7 will be running off the Micro SD card correct? Does it matter what type of card I use? Does anything get saved to the NC internal memory such as downloads etc? My big question is, Does the Micro SD card's class have any effect on performance? Would getting a class 10 vs class 2 make a difference? Thanks.
The higher the class the faster the performance it will be if ur running the rom from the sd card which you plan to do.
I am running from internal memory but all my stuff is saved on the memory card naturally, I don't have to guide it there it just does it.

Will it perform better from internal memory than class 10 micro sd? If so is there a guide to do this and would it still require an external card for other stuff? I plan on using CM7 stable and the guides I've seen are for booting from external.
Check this post it might help you decide on what sd card to use and wether to run from internal memory or external: http://forum.xda-developers.com/showthread.php?p=18430544

Thanks... I must have missed this in my search(es).
It has been extensively discussed here. The class is less important than getting a Sandisk card. Class 2 or 4 are fine. They will perform about as well as internal memory. Any others brand, even those with a higher class will suffer more FC's and not perform as well. My class 6 PNY WAS NOT EVEN CLOSE TO A CLASS 4 Sandisk.
I don't know the thread, but it is well documented and should be able to find via search.
My recommendation would be to run CM7 off the internal eMMC and use a blank SD card for backup and storage. In that case it doesn't really matter what card you use but since they are all fairly cheap these days I would get an 8GB card class 6 or higher. One for each Nook. Also get a 3rd card that you will use as a bootable card for the installation. Keep that card handy in case you ever need to reinstall CM7 or if you need to restore to stock for a warranty claim. I kept mine and keep a copy of my currently nightly (201) as well as a full stock ROM (1.3). I already had to make use of it once when I needed to have my Nook replaced under warranty.
Thanks everyone for helping me get pointed in the right direction. I plan on installing CM7 to internal memory and have everything I need to get started.
I don't know if you care, but I would do a first run on the Nook Color and register the device with B&N prior to wiping it and installing CM7 in case you run into warranty issues (such as replacing the USB cord) which you will need to have registered for.
Otherwise +1 on the Sandisk micro SD cards, class # across manufacturers varies wildly. My Sandisk class 4 16GB card outperforms both my class 6 PNY and Transcend 8GB cards in small writes/reads. I had random force closes on the Transcend when I first installed CM7 before I switched to the Sandisk.
EMMC > SD install if you like to tinker with your installs --- the agnostic sd card image here has a barebones recovery and you will not be able, afaik, to manually wipe partitions etc if you so desire or flash non-signed roms and themes (please correct me if I'm wrong, which I very well may be).
I used to dual boot (stock EMMC, CM7 SD card) but as things have progressed this year there's no reason for me to stick to even nootered stock --- the performance difference between stock and CM7.x is massive, and the big bugs have been fixed (SOD, battery drain). Even if you like the default reader app, there's great generic ereaders out there (and now with Overdrive app from Google Market, the ability to borrow DRMed epubs like you could with the native Nook reader client).
Just one note I would add to the above. When deciding between an internal install and dual boot, note that some have reported issues with the latch for the sd card breaking with frequent removals of the sd cards. This latch repair requires factory return. I, personally, would recommend internal install with an sd card for storage. This will prevent frequent removal of the sd card and will extend the life of the card latch.
Just my two cents.....

You don't have to remove the sd card to boot stock.. just power up while holding the N button and you will be given a choice of which system to boot.. this is true if using the Size Agnostic procedure documented here on XDA.

The point is well-taken because every time you update your rom, you'll have to take out the card, BUT you have to do that even with the internal memory (emmc) install. But as the previous post indicated, you don't need to take out the card just to boot to stock. I would strongly recommend that you not install the rom to the emmc until after your warranty expires. That way, if you have any problem with the NC, you can simply take out the card, and you're back to stock, i.e. none of the "restore to stock" stuff you'd need to do if you put CM7 on the emmc.

I have watched and read for some time here and been putting the android switch off because of time. Now I would like to try to run a build or two from my MicroSD. I have seen several places that a formatted SD is best. I have tons of WM's apps stored there so I reluctant to format over them.
I would like to be able to dual boot with my current WM6.5 and android.
I thought about getting a second Micro SD to mess with but if I had to swap sd card it would be a real pain. I have a Otter box for my HD2 and just getting the cover off to reset it is terrible.
Can I partition my Micro SD for wm and android? or does it have to be two cards?
Since you are staying with winmo and running android from SD, there's no need for partitioning the card,,, the android build simply lives in a folder called android on the SD card.
Partitioning the SD card is for nand android that uses apps2sd.
If you want to format the card,(or if you decide to partition) just copy everything off onto the PC, format (or partition) it, then copy everything back.
I have all my winmo files and folders still on my card, with no issues (running nand build with partitioned card,,, the android stuff and winmo stuff all sit quite happily together with no interference)
Samsamuel,
Thanks for the reply. That is good news. I know that the class of the card makes a different in performance but should I even try it on the class 2 16gb card what came with the phone?
I'm using a 7 or 8 year old 2gbsandisk, no idea what class it is but can't be that great, and I have no problems, no lags, nothing to indicate any performance issues.
I'm putting anew 16gb card into my nook to replace the 2gb that is currently in. What do I need to do to make sure everything works correctly? This nook running CM7 is only 2 days old so I really don't have installed yet.
If you plan to use the card for running CM7 or phiremod you need a sandisk class 2 or 4 card. If not, there are no card issues that I'm aware of. If you're asking about moving your apps I'd just reinstall. Titanium Backup is the preferred app for backing up and restoring apps if you want to try it. There are threads about moving CM7 card installs to larger cards. I think you just image the old card, put the image on the new card and expand the partition to fill the new card.
I found a Sandisk microsdhc 32GB class 4 on amazon for $59.
Would it work?
"Would it work?"
Dunno.
This thread is the clearinghouse for all info about which sd cards work for booting. There's not enough information about 32GB cards yet to know how it would work. That's a decent price though so it might be fun to get one and try.
I just used Clockworkmod 16 gig to root my nook color. Now that its done I want my 32 gig class 4 card back to stock to utilize its full capacity. How do I unpartition the card. I used win32diskimg to write to the card. My windows 7 will only acknowledge that there is ~14 gigs on the card.
Please help I am a noob but I can follow directions. I'm actually also wanting to do this so I can bring my nook back to stock and then dual boot the color encase something goes wrong I can get it looked at at B&N.
Thank you all for the help. I search the forums and couldn't find a fix.

i couldn't find the program on Sandisk .com. I did find a free one when I hunted for SD formatter.

Just not sure if it will work on Micro SD cards
go into menu... device settings... unmount sd card... format sd card
Thanks
It worked great
Would appreciate some guidance, if anyone can help...
In December we got two new Nook Color Devices, one had 1.2 and the other 1.3. Had one 8gb micro sd card, and without understanding much about it, I followed verygreen's instuctions to create a card for dual booting. The 1.3 machine was used for installing cm7 (7.10) and the latest gapps file. But the card was then removed from that unit and inserted into the other Nook Color which had 1.2 in its firmware. I now think this was improper but am unsure what the repercussions were.
The system was used succesfully for several weeks. Occasionally the Nook side was booted from menu. Then suddenly after a cold boot, CM7 started but the virtual sd card was not recognized. Removed the card from the unit and investigated using Windows XP and Minitool Partition Wizard and found the "CM7 SDCARD" partition was corrupted. I reformatted that partition in Minitool, and then used the card for about another week in the 1.2 NC. At that time multiple partitions on the card suddenly became corrupted and fearing the sd card itself was defective I ordered some higher quality sd cards (now have 4 8gb sandisk class 4 cards to play with). Meanwhile the 1.2 NC accidentally booted into the Nook side with wifi enabled when it was charging and updated itself to 1.4.1. Before receiving the new sd cards, I reformatted the possibly defective sd card and recreated dual boot system using Verygreen's instructions (in the 1.3 unit but transferred into the 1.2 unit after creation). I was able to restore some of the apps using Titanium (but only because I had copied some of my original backups to my pc)
The unit with 1.3 on it had not been used much with wifi, and it still had/has 1.3 on it. One of the new cards is now in that NC (created as before with the Verygreen instructions).
I'm in a quandary what to do with the other unit.
Could using the 1.3-created sd dual boot card in the 1.2 Nook have caused partitions to become corrupted?
Where are applications going? Doesn't look like they're in the large sd card partition. I didn't think I had that much on there, (just some free apps from google and amazon) but I might I have run out of space? I never elected "move to sd card" or "clear cache" for any apps and don't know if that is a requirement when you use dual booting.
I haven't found instructions for what to do to create a dual boot card for 1.4.1. My original 8 gb card is in the unit, but I'd like to create a new boot card using the higher quality medium. Just want to understand what's happening. Is use of a 1.3-based card bound to lead to more corrupted partitions? Any suggestions on how to create a reliable dual boot card for this unit?

Can't tell you what issues you may be having with the sd card, but verygreen's "dual boot" (it's not really dual boot, but that's another story) method is independent of the stock rom (1.2, 1.3, 1.4, whatever). When you boot to the sd card, everything needed is on the card. When you boot to the Nook, either by using the sd card menu or removing the card, you get whatever stock ROM is currently installed in the emmc. If you properly created the sd card, you can insert it in any NC and use it.
I read through all and by the end, I'm lost
Anyway, if you are dealing with verygreen's uSD cards, you should be all set and not to worry anything on the eMMC. It's independent.
As why those partitions corrupted, I don't know as I never hit that problem. Just curious, why do you say it corrupts?

Oh well, if no one else has had the issue of sd card corruption hopefully its not a side effect of using verygreen's image together with cm7 7.1.0, google apps and user apps.

The behavior was a little different each time. Has happened 3 times now.
Once it totally locked up. Powered off and back on. Got my home screen with icons but in the notification area an image of the sd card persisted for maybe 5 minutes while the unit was otherwise locked up. Finally the sd card image cleared, but es file explorer empty sdcard. When tested on the PC, that partition's data was corrupted. Recovery (using pc software) retrieved a bunch of files but without their proper names. That time my apps were not destroyed. I didn't have to redo verygreen's procedure, just reformatted CM7 SDCARD partition.
Another time I had powered off. Restarted and it booted in Nook instead of CM7. Removed the card and tested on the PC and both the boot and CM7 SDCARD partitions were unreadable. Didn't attempt any recovery. Wiped out and reformatted the card, then redid the verygreen procedure on it.
The third time (last night ) was more similar to the first time. I got some forced closes and couldn't get back the status bar. Rebooted. Got the sdcard icon showing for about 5 minutes. When it cleared, my files were inaccessible. Removed the card and tested on the PC. CM7 SCDARD partition content was corrupted.
The (bad?) sd card didn't give any errors when tested prior to the break downs. Its labeled as a sandisk 8gb class 2. Was a gift.
I'm back up and running after redoing the verygreen procedure using one of the new sandisk 8gb class 4 cards. This time I actually used my unit instead of another to do the unpacking/recovery loading of cm7 and google apps. I've never applied any of the nightlies. Maybe I should look into that. Also have never deliberately done any other procedures, such as overclock it.
Praying the corruption issue doesn't hit me again. I guess my NC's internal flash drive could possibly be defective. If so, at least its still under warranty.
Under storage settings.
Shows me SD Card total space 116MB Available space 12.52MB. My SD card was a 32 gig class 10.
Internal storage 4.9GB
Available space 4.33GB
Also C7 will boot without memory card in it. My cousin helped me root it and we used the SD card to root it. According to him I should be able to take the SD card out and boot into the normal NOOK settings. This correct?
I am getting errors when I try to install things to SD. Tells me there is not enough room.
Sorry if this doesn't make much sense still very new to this.
Thanks for the help.
First, go to Settings>CyanogenMod settings>Application> and make sure Use internal storage is unchecked.
Then go to Setting>Storage and let us know about SD card, Internal and Additional storage values.

Sounds like you installed CM7 to the internal memory, not to an external SD card. that's probably why you are seeing the space available on internal memory, but not the SD card. There is Verygreens's method to install CM7 and CM9 to the external card, leaving the stock Nook ROM in place, but it doesn't sound like you used it. To get answers to most of your questions, go to Leapinlar's great information page here:

Yes, I agree. It sounds like his friend set it up to install to SD by burning the image to the card, but somehow flashed the rom to internal memory instead. That would explain the 5GB internal space and 116Mb SD card space.
He needs to reformat the SD card to get the full size of the card available.

Well sounds like the stock nook interface is gone then. No big deal. Do I just reformat the SD card through the settings in android? The option states Erase SD Card. Would that be what I want to do?
Also not sure if this is related. But sometimes C7 wont boot when I have the SD card in. Take the SD card out and it boots just fine.
Well I grew a pair and did the Erase SD Card. Now it is showing 29.66GB.

LOL. Good job. Yes, stock Nook is gone. I can help you get it back if you want it, but most never miss it. The only reason people want it is for warranty or if they want to have kids books work.
Random side question but figured since I have ya here.
Any idea on a good note taking app for android? As in for school notes like during class?
