A defective SD would be a strange thing as I was using it flawlessly with an o3ds, but understood and appreciated. I'll put it to the side for now as I've been banging my head against it for probably 10 hours now.
For the record this is a reputable brand (Sony) purchased at a big name retail outlet and not from a shady online dealer. I performed a surface scan to verify the SD card is not (immediately) faulty, result here.
Thanks again and, whatever it is should be interesting.
EDIT:
I'm in the process of experimenting with my SD card(s). I formatted a 16 gig on my computer, and then partitioned it using EmuNAND9 (launched from my 32 gig), and then did the same with Decrypt9. The SD card was empty but the partition folder and the emunand backup. it successfully restored the backup. I am now going to test the same procedure but with the 32gig card. (Empty/fresh card with no other files than the NAND.bin)
EDIT 2:
AAaaannd... It failed at the same point. That is bizarre. And unfortunate. If the SD card has no errors on a surface scan? What could the problem be? If it is just a fault card, I apologize for wasting your time, but..
