This hard drive, which is a 2nd drive, worked fine until I tried attaching an IDE hard drive to the primary IDE cable, which runs my CD ROM. After that, the 2nd HD shows up during the POST test but is not 'mapped' after windows boots. Nor is it accessible at a DOS prompt. No pins or jumper have been changed. Haven't tried diskmgmt.msc yet but I will and will post back. I'm thinking of pulling the battery, fdisking the /mbr and hard drive (primary one) and reinstalling AGAIN. Thanks and I'll let ya' know how things go. Oh yea...running SP4. Don't forget, this is a SCSI drive and I can't find somewhere to initialize it in the BIOS, which I don't think there is way to do that anyways. Regards.
