I bought a Nook color so I could root it. Well, I did but I used a 2 year old, simple 2g sd card. I couldn't wait for my 8g class 6 one to come in. The cm7 seems to be running fine off of the 2g card but my question is, would I be better off redoing everything on the 8g class 6 card?
Did you install CM7 on the card, leaving the stock B&N rom intact?
If yes, then I suspect you'll be running out of room soon. Unfortunately, redoing it would mean losing everything if you don't know how to copy the contents to a new card and resizing it.
If you installed CM7 on the NC (eMMC),
replacing the B&N rom, then it's a simple matter of copying your 2g card to the new one.
Either way, yes, 2 gb is a bit small. I use a 16 gb card, but many here use an 8 gb. If you installed CM7 on the sdcard, then you probably want a 16 since everything is on the card, nothing on the NC.
I'm a noob too so correct me if i'm wrong but once you installed cm7 via the card, you don't need it in the unit anymore......so, you could pull it.
I believe you're talking about the bootable CWM recovery disk, which you have to pull if you want to boot the internal rom, o/w you'd be in recovery all the time.
Too many ways to install CM7 here so it does get confusing, esp. for those of us who provide support.
FWIW, I'm not a big fan of installing installing a custom rom on the sdcard, leaving the stock rom intact. I can see why it's done and why someone might want to try it, but it's a temp solution so as to not void the warranty IMO.
