My guess is that the drive is formatted with the NTFS file system, which is unreadable by Windows 98. You'll need to reformat the two partitions before you can use the drive.
I have an older hard drive (4.3 GB partitioned to two drives) that was operating in an NT. I need some files from it on a 98SE, so installed it on the 98SE. I did the BIOS change to look for the drive -- Primary Drive one. It doesn't show up on My Computer, but it does show up in BIOS as a 4.3 Gig drive. The 98SE computer is an older Dell.
What I want to do is get a backup of a couple programs and restore the data into newly loaded programs.
