Is the second drive actually a second physical hard disk fitted inside your PC, or was it merely a second partition on the same physical disk? If it was the latter, you may have deleted/overwritten that partition when you re-installed Windows, so now you only have one partition instead of the two you had before.
Thanks for your reply.
The 2nd hard drive is actually 2 physical SATA drives configured in a RAID 0 setup.
All the drives are the same ones that were in the system prior to the XP re-install. My BIOS see's all the drives. The XP install disk asked (after I loaded the SATA / RAID drivers) which drive I wanted to install XP on, so the install disk saw all drives.
My computer, properties, hardware, device manager shows all drives.
Start, Control panel, administrative tools, Computer Management, Disk Management shows both -- but the RAID drive is shown as Unallocated space.
Double clicking My Computer only shows 1 drive (C:)...
The stuff on the RAID drive is my personal phot's etc, so I don't want to reformat it...
