What's the best way to do this?
I believe I have vintage PCs with ISA slots and ST-506 hard drive
controllers, so that may be an option.
However, the drives I want to archive are not from a PC system, but
have the ST-506 electrical interface.
Because the ST506 (and ST412, which is actually more likely to be what
you have) interfce is a low-level wraw one, the dat encoding depends on
the controlelr, not the drive. It's entirely possible that no PC
controller could make sense of these drives.
Am I correxct that a DiskFerret with a simple adapter board can read and
store the raw data stream from such a drive and leave the decoding to
software o nthe host PC?
What machine are they from? Do you know anythign about that machine's
hard disk controller?
