Well I'm usually not one to take risks with my hardware but. I went ahead and tried this with no other feedback and it worked. I had a bit of a scare, I ran the ID updater and rebooted. My SCSI card came up with a blank device where the HP drive should be. Then I shut down and rebooted and it came up as the plextor. I went ahead and updated the firmware and all is good. This looks to the real deal, thanks for the work!
