Hello! I am considering purchasing a Seagate Barracuda 4.3 gig SCSI drive, pulled from an HP computer, for use in my trusty but rusty Quadra 840av.

The specs say this is a "Low Voltage Differential" (LVI) drive.

Can anyone tell me if I can use this? I have an old drive box in which I can test it, as well as an additional sled for use in the Q840av.

Your help would be most welcome!

The LVI has to do with the technology used in the drives electronics and has no effect on the use or usability of the drive.  It's basically in there for marketing purposes.  LVI indicates that the drive's electronics use a very sensitive threshold detection scheme to allow the reliable reading of data with very low signal levels.  This means that the drive manufacturer can cram more bits onto the drive without adding more platters.  

All of this is internal to the drive itself and it will appear as a normal SCSI drive to your computer.
