Have 40 GB western digital for 2nd drive.No OS, only mp3 music.Temporarily removed drive to format another drive for another machine.Accidently plugged 40 GB back into IDE cable with machine still on.Still have “D” icon in “my computer” but when I try to access I get a “directory is corrupted” error.Can still see partition with Fdisk.Brought up drive letter in DOS.When I try to access drive in DOS I get a “missing command.com” error.Sure there’s no command com because windows 2000 is on primarydrive.Over 5,000 songs on drive.Please help..
