Does anyone know if it’s ok to run an RLL drive in MFM mode using an MFM
controller?

    Re: RLLS drives as MFM…

    Ya.. this is no problem… You should not do the reverse though.

    yes you can do that. I ran a ST238R as a 20 megger for years. The only
    difference between the drive is the 238R was tested with the tighter format
    (a ST238R is basically the same as a ST225, just cramming in more sectors
    per track) Im using my Seagate ST238R as an example, but a real example.

    I have done the opposite, ran into some problems down the road since a
    MFM drive isn’t tested to take an RLL format, its risky
