 |I have successfully RLLed both Seagate and Micropolis MFM drives.  Make 
 |sure you run the RLL controllers surface scan, and add found defects to    
 |the bad track list.

Seagate recently closed the window on RLLing it's MFM drives.  I have a 2 year   
old ST-225, and it RLLed fine.  I have a 1 year old ST-251-1, and it will not   
RLL, preiod.

I now have a new ST-4144R, (RLLable ST-4096) ... it RLLed to 122 megs just   
fine.  Beware that disk manager will not format these large drives, no matter   
what it claims.  The new address (and this works for AT's too!) is g=cc00:5   
... I have an AT classer with a WD1007v-SR2 1:1 interleave controller, and   
after I tossed DM Iit took me all of 30 minutes to RLL, partition, and format   
all 150-odd megabytes.  The 4144 is first, the 225 is second.

I finally have room for a sizeable (read grreater than 30 megs) XENIX   
partition!
