I have an Adaptec RLL controller and a Seagate (RLL) ST238 drive.
Either the controller or the drive (or both) is bad.  
Since I don't have an extra RLL controller or RLL drive, Its difficult
to trouble shoot.

Since I'm under the impression the ST238 (RLL) drive is the same
as Seagate's ST225 (MFM) drive (with the difference being something
along the lines of different platter surface density), I'd like to
use a known good MFM controller to test the ST238.

Q: Can I use a MFM controller with the ST238?
   (I understand that after low-level formatting, the storage will
    be reduced (from the ~30Meg using RLL to ~20M using MFM).  However,
    that's OK by me.)

Any help would be *GREATLY* appreciated.
Thanks in advance.
