[Lirarn]

Today when i came home i tried to open the shortcut to my music but it couldnt find the specified location. Then i clicked start, my computer and tried to click at the D drive but there wasnt any D drive. Neither there was any E drive and i have all my music there!!!! Thank god my WoW installation is on the C drive, because the computer could find just the C drive.
Could someone help me please. Yes i have checked the cables.

Open the case, check for any loose cables. Reboot the computer and enter the bios to see if they are recognized. Check in disk management to see if they are listed just needs a drive letter attached to it. I've seen it happen. Or your drives have crapped out on you.
