Price I quoted is from TJT Intl, and they have a 30 day guarantee, except they charge a 15% restocking fee, so I was hunting more assurance. I want to stick it on a bus with 3 existing IBM 34330W drives, and the 34560 will be the only LVD drive. Those old Quantum differential drives burned a warning message into my soul. That was a 50 pin bus, this is 68 pin, but I'm still wary. The TJT guy says he *thinks* they work ok with ohter drives, excepting the 34560 will not provide a termination, so one of the 34330's will have to do that (no problem there). I just want to see if someone else has some direct experience with the DDRS34560W-LVD. Sure would make me feel better. > > > On Thu, 13 May 1999, Chuck Robey wrote: > > > Anyone got experience with an IBM scsi drive, DDRS34560W-LVD?
