I have a SunRem drive also.  It's a 20MB Kalok MFM hard drive.  KL320 I think.  I have no idea if/how you could low level format the drive.  Luckily, my drive works.

Since the SunRem drive is in two pieces (the drive and the controller), you might disconnect the hard drive and see if the Lisa will boot up with just the controller.  It might tell you the controller is okay.  I have not tried this so I don't know if this will work and since my drive is working (they have a terrible reliability reputation) I'm not messing with it.

My drive boots up MacWorks Plus 1.1 I think.

It is probably a standard Miniscribe drive with a normal 4 pin disk drive connector.
They have a high failure rate. I've bought two SunRem drive assemblies and neither
drive would get through initial calibration. There was some discussion on the list a
while back that drive replacement would be difficult since the firmware has no way
to low-level format a replacement drive.
