Old drives like an 8GB frequently had to use 3rd party partitioning software to get the old machines they worked with to recognize them. IF they are not the boot drive then the software that enables the drive doesn't work, and they aren't seen. IF you run FDISK do you see the drive when you select option 4?
When you plug in a drive with a single partition it will become the D: drive, if it actually works, pushing the first drive's D and E partitions to E and F.
I was trying to install a Maxtor 8GB hard drive from an old machine into a Gateway PC with a 5GB hard drive,CD-ROM drive and 2 floppy drives present. Both hard drives were originally jumpered as master drives and running Win98 SE as FAT32 drives. The 5GB is partitioned with 3 drives (C,D, & E drives). C drive has Win98, D drive is applications and E drive is overflow for backups and swap file etc. The 8GB drive was originally one partition (C drive). I jumpered that drive as a slave and installed it into the Gateway PC, booted up the machine, entered Setup to auto configure the new hard drive and rebooted. The CD-ROM drive is showing as F drive. On reboot, the bios startup routine identifies both hard drives and the CD-ROM drive. The machine boots up into Win 98. I look into device manager and both hard drives are listed; generic IDE hard drive 0 and 1. BUT, when I open My Computer, it only shows C,D,E partitions and F drive (CD-ROM). The Maxtor 8GB hard drive isn't listed in My Computer. What do I need to do to make it show up? Any help would be greatly appreciated. Thanks.
