OK, on closer look it appears as though these Eve
drives might be
ESDI/ST-506 and not SCSI. If they are ESDI, how could I archive them?
1) what were the drives connected to? If it is a custom controller you
either have to have enough knowledge about the machine to write a block
level dump program, or build something that can extract and then interpret
the data stream off of the disc. BTW, ST-506 is no easier than ESDI if you
are down at the bit level (other than the ESDI data separator was on the drive)
2) if it was a standard thing like a scsi to st506 or ESDI bridge board, things
are much easier. ESDI was new enough that bridge boards like the Emulex MD21
had inquiry commands so you can get the drive geometry. older boards require
the system to configure the board with that information, so you had to know
in advance what kind of drive is out there.
