[Q] SD Card Error (can't mount /sdcard)

view story

http://forum.xda-developers.com – Hello, I've been successfully rooted my Galaxy S (i9000) since the first day I got it. Installed CM10, Slim ICS and other ROM's with no problem. A few days ago I tried to flash the latest (beta if I'm not mistaking) of Slim ICS and somehow everything got screwed. Sadly I don't have a Titanium Backup. The problem is with the internal memory I guess, as I can use an external SD card (The one that you place in the slot). I've tried everything from Ezboot, Darky ROM, pit files, and various stock kernels and ROMs with no success. I've also tried flashing a dbdata file with no success. From w (HowTos)
