By the looks of it, it's a dead fujitsu.
Is it on same IDE channel as master? (You did say PRIMARY master and SECONDARY slave)
If it is not then it must be set to master mode also.
Slave drive without master (on the same channel) can mess up BIOS HD detection.
Only, XP bypasses BIOS, when it comes to detecting drives.
Try seting it on master mode, and it just could bring it back to life.
