I have a Quantum P105S from Hard Drives International. When I first got it, I had an Apple DMA SCSI -- I used both the P8 utilities and ADU to partition/format and neither gave me any problems. Later I sold my DMA SCSI and bought a RAMfast. Still no problems, this time using the RAMfast's built in HD management software (rom 1.2 I think). Maybe the Quantums have internal termination you haven't removed? Todd Whitesel toddpw @ tybalt.caltech.edu

I have a Quantum ProDrive 40S that I bought from a mac mail order house as an internal drive and put into an old ProFile case. I have had no problems using it with my DMA SCSI card. It came low level formatted and so I just did a partition and high level format. These drives are supposed to only format at 1:1 interleave regardless of your specifications due to the cache which is why I did not try to reformat it. I am using internal termination rather than external. Both partitions appear and can be used from all the software I use. -- Stephen Harker phs172m@vaxc.cc.monash.edu.au Monash University
