Universal re-partitioned your sd card from 4GB to 2GB? read this.

I've come across a little SD recovery app for 4GB cards that were partitioned for 2GB.
This is a transcend app, and they state its only for their X150 SD card, but i don't think there should be a problem recovering other cards.
I don't think there's any difference from other SDs.
(I haven't tried this cause i dont have a 4GB card, i just wanted to bring this to your attention...)
Try it out and report the results..

Good Luck!

[Q] MICRO SD FORMAT/PARTITION? OR TWO Cards?

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.

[Q] New SD Card

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.

Nook Color Noob Questions

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.

Why my HD2 android won't start with my SD card?

My HTC HD2 works with my Transcend 4 GB microSD card, but it won't android won't boot up with my 8 GB Verbatim microSD card. Do I need to format it or something? Thanks!

Are you sure you have the correct set up ? (Files are copied to their destinations)
Try to format it to FAT32, and try again.

I`have just formated it to FAT32 and still the same problem. What files are you talking about?
PS: Sorry to bother you with "stupid" questions, I am pretty noob in this

I have read that Verbatim SDCards can cause problems in the build; booting or running, SanDisk is your best bet, but you may still be able to get it running,
Im not a dev; just brought SanDisk as a result of this,

It depends on many factors. Which Android Rom do you want flash, does this need Ext 3/4 Partition on the SD Card ? Do you have flashed the right partition size ? Read the installation instructions of Rom you wants to flash, there you mostly find all information.

Are you talking about NAND or SD? If NAND, make sure the ext partition is set up correctly, as this is where a lot of the apps are stored. If SD, then I would assume you know how to install an SD build so it could be a problem with the SD card being incompatible as alex.odell.2011 said.

I've had similar problems sometimes with my SD card; my HD2 wouldn't boot unless I took the card out then put it back in once it was booted. The only thing that I thought might cause it is something CWR related on the SD card, since I had used it in my Hero and Droid 1 as well to flash ROMs to them. It was a class 4 16 GB Sandisk, if that helps at all.
