Hello there,
    I do agree with you that putting RLL controllers on MFM drives 

is quite a risk, but I must say, it isn't impossible.  I have RLLed 
an ST-225 and a Miniscribe 3650 (which is exactly the same drive as 
the RLL rated 3650.. 'cept its not certified) for a year or so now 
without a hitch.
    Yes, I may be slightly crazy, but most of my data is not EXTREMELY 

important.  I have backups..  From what I know Seagate no longer allows 
their non-RLL certified drives to use RLL.  They have done something 
with their drives to disallow this.  In their older ST-225's RLLing 
is possible, but it isn't very safe.  I suppose I was lucky.  From 
what I know you need a ST-225 above revision 3.  I'm not sure when 
they started changing their drives to disallow RLLing.
    Oh, BTW, I will tell you if my drives crash.. but by that time, 

it may not be due to the RLL (these drives are pretty old).
 
                                Wayne
