Of *course* you need to back up your hard disk before replacing the
controller. That actually goes any time you replace the controller, even
with the same model: there's no guarantee of data retention across a
controller change for an MFM/RLL drive.

But to the point: I posted a list of known RLL-able drives early this
year. In summary: any drive is RLLable except for certain ST225's: those
with S/N under 1,000,000 and/or rev level less than MLC3. I still have
not experienced a single problem with an MFM->RLL upgrade that wasn't
due to a controller problem. Pick the correct Adaptec controller and you'll
have no pain!
