i have a western digital 160gb hd that i partitioned into two drives (75gb and 74gb). everything was working fine until i ran an error check on the 74gb partition last week. i got the error "windows was unable to complete the disk check" and after receiving this error, i noticed that the amount of free space on the drive was significantly off. the drive capacity was still 74gb but the amount of free space some how managed to drop from 56gb to 35gb even though no other files were copied onto the drive. i tried error checking again but was still getting the same error message. it wasn't until after installing sp2 and removing the controller card that the computer was able to complete error checking on the drive. the drive is still short 21gb of free space though. does anyone know how i can get that space back?
