	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.
