[elosogrande7076]

Hey guys....i just flashed a new rom (Ivan's Vista Rom) and noticed that after doing so my storage card is now gone! Has this happened to anyone....more importantly is there anyway i can get the info back (i know it sounds like a stupid questin but i figured i still ask since i have a lot of new stuff that wasnt saved since my last backup) i dont think its the rom (i beleive i flashed the rom a while back) and i am constantly flashing roms....any help i greatly appreciate it...
