I assume "far from being helpful" means that IBM told you they don't
support that drive in anything other than the PS/2 products it was
meant to be in.

The drive you have is an ESDI drive... sort of.  It's supposedly been
modified some way to "tweak" the performance a bit.  I've heard the
disk partitioning software by OnTrack systems can take one of these
ESDI PS/2-type drives and use them on a "standard" ESDI controller.

Just a note: IBM stopped making these drives a while ago, and dropped
ESDI totally in favor of some really mean & nasty performing SCSI
controllers.

I have a ps/2 70 Meg hard drive that i would like to put in my
386 AT computer.  The only problem is i can't seem to find anyone
who knows how many heads/cyc it has.  IBM is far from being helpful.

Any info would be appreciated.

It is a "Type:  0667"

thanks

Yes, fit is a ESDI, but i can't reformat it without knowing how many heads
and cyclendars it has.  From what i have heard, is that when PS/2 drives
are shipped out fro the factory, they are formatted in some "special" way
and will not work on a "regular" ISA type machine.

From what i understand i can reformat this drive so that it is again
"normal", but it would not be able to work in a PS/2 again after doing
this.  In any event, nobody seems to know antything about this kind
of stuff, including IBM  -  at least the people if 
of stuff, including IBM - atleast the people i have talked to -- Everyone
pleads ignorance.
