It looks like you've got a standard WD PC/AT HDC (WD1003-WA3) which will
turn out compatible with the Miniscribe 3053 and the ST-251, The big ST
drive, the 4384 is an ESDI type more or less equivalent to the MAXTOR 4380E.
I believe the CDC (same actual MFG as the Seagate, just the prior owner's
label before Seagate acquired them) is about half that size. If I remember
corretctly, it's half-height as well. I believe I have several of these,
but in non-functional status. Though the interfaces "look" the same, i.e.
same cable connectors, DON'T CONNECT THESE ESDI DRIVES to am MFM controller.
They won't work. The 3053 is another one I've tossed out/given away. Once
they don't work, the application being for MFM and where a relatively small
drive goes, I don't usually attempt to fix them. These two are both half
height MFM types of about 50+ MB capacity unformatted. Check for precise
details on www.theref.com, but IIRC, they have close to 1K cylinders and
either 5 or 7 heads.
The ESDI drives need an appropriate controller e.g. WD-1007 of any subtype,
or even the 1005 or 1009. These are really excellent examples of their
type, so I'd hope you can get them going. The WD controllers can deal with
the large number of cylinders so that's not a problem.
