I have the impression that the X1215 is just a rebadged CDC Hawk, i.e. a
normal SMD drive. At least the P825-007/P825-008 is a standard CDC module
drive (see P856M/P857M system handbook pages 17-22 to 17-25).
HP7900 drive does not include the data separator,
it's in the controller.
I had considered using an RK05 or an RK03 in place of the HP drive on an
HP9880 system, this is one thing I would have to sort out (it is not
difficult!).
Me too, but the HP drives spin at 2400rpm instead of 1500rpm. You would
have to modify the controller for the lower transfer speed.
IIRC the Shugart SA4000 drives had a clock track on
the disk and a fixed
hed to read it. The drive provided both the read _and write_ clocks to
the controller.
Same with SMD drives.
