I was scared - the boot was stuck on the words before the N shows up - figured up it was from the SD card - what is weird is i can put it in after it is booted up - and see my stuff, but it wont boot with it. So I have copied over the couple books that were on there, and am going to reformat it, and then see what happens. I've rooted it and love it, was scared it was bricked!
Yea sounds like a bad format or wrong file system type. I would backup (copy) all my stuff off the sd card and then let the NC reformat the sd card: Boot your NC without the sd card, then insert the card, go to settings > device info > SD card > format sd card. Then plug up to your NC and pc and copy your stuff back over. reference: NookColor Format and partition your SD card back to a usable state - nookDevs
yep, that worked - what is odd is i have been using that sd card for days with it - it is an 8gb that used to be in a nokia phone, that i formatted on the computer and put in empty in the nook right after it was rooted. but all good now...
It's probably superstition, but once I learned that formatting the card in the NC is the best way to repartition (after programs like winimage create a partition), I now format the card first in the NC! -Matt
