I just had to reformat my hard drive, due to a virus getting into my system and trashing everything. After reformatting my hard drive, I installed my CD-ROM drivers to drive C yet when I try to change to D drive, it tells me it is an invalid drive. I seem to remember running into a similar problem when I first installed the CD-ROM drive. I had to add some lines (3, I think) to my config.sys file or autoexec. bat file but I can't remember what they were. Any help here would be greatly appreciated. Thanks.
Note: This is not a physical problem. My jumpers are correct and the drive works.
