Buffalo External MO Drive MOS-S645R/A - Operation Not Confirmed This is a SCSI-connected drive. No box or manual included. AC adapter is included. I have disposed of the PC with SCSI, so I have only confirmed that it powers on and that MO disks can be inserted and ejected. When an MO disk is inserted, it appears to be reading. To keep the price down, it will be shipped in simple packaging.
