I would like to thank Alex, Paul, and Michael for the input regarding the original SCSI post . It seems there are varying opinions on the use of SCSI in OS X. I have also come into an OEM copy of 10.3.1, that I am going to use on the second partition of the 80 Gb western digital that is my boot drive. Although I am long time Mac user, I have yet to feel completely comfortable with framework of OS X. The original purpose of this post was to find a use for these SCSI drives. Will they work and be stable without any issues.
