The only potential problem I see is if the drive from your old computer is not FAT32 (depending on what OS you had on that one). If that's the case you might need to run Win98's FAT32 conversion utility. I would also recommend you go into you BIOS settings on your old comp and write down all the info about this drive before you remove it, in case your other system's BIOS doesn't auto-detect it right. Other than that it should be a piece of cake, as long as you change jumpers to make it the Slave on your primary IDE port.
