(Hmm, i put this here because i didn't know where else to put it soo mods, do your job if needed! ;P) Anyway, I know many here use micro sd cards for gaming and/or phones for music, stuff, etc. Well, im using a phone that can have an micro sd for music and stuff. A few weeks ago, i was able to put my micro sd(2gb) in the adaptor and was able to drag files to it without a problem. Last night i wanted a bit of more music, so i put it(microsd) in the adaptor and it shows up as Removable Disk (F. I doubled-click away but this time it said i needed to format it. So i said 'sure why not' since ive got nothing important in it. After clicking to format it, it stopped and said it failed to do so. I restarted my pc and it did nothing. I changed the drive letter (because i remember reading that if you did that i will show up) but nothing happened. Now if i doubleclick on the Removable Disk thingy, it says "Insert Disk in Drive (F" SOO..i bought a new micro sd 4gb (includes a new micro sd adaptor) and thought it would work. Well, same shi* Frustrated i was/am. Maybe someone here has a solution? ;-; USB 4gb that i have works fine, f.y.i.
