> No you can't use a RLL with an MFM controller. Similar but not the same.

Sure you can.

If the interface is the same (most likely the ST506/ST412 interface 
here), then you can use an RLL-capable drive with an MFM controller. You 
won't be able to read what's on the drive, you'll have to low-level 
format it, and you'll only get about 2/3s the stated capacity. But if 
you're trying to replace a hard drive in some old machine with an MFM 
controller and you happen to have an RLL-capable drive around, it'll work.
