Hi, A friend of mine has a 72mb MFM drive (ATASI 3085) and he would like to try and format it using an RLL controler. If he succeeds great. If he fails, what? Is there any chance he might damage the drive during the testing? Would the drive still work with an MFM controler for sure? Thanks, Thanasis ------------------------------------------------------------------------------- "Has it ever occured to you that God may be a committee?" R. A.

No chance of damaging the drive. It will still work with MFM controller. 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. Chewey, get us outta here! kaleb@mars.jpl.nasa.gov (818)354-8771 Kaleb Keithley

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! . . . . . . . . . . . . . . . . . . . . . . . . . . . cmaidt%metnet@uokmax.uucp . . . postmaster@metnet.fidonet.org . . . ...!apple!uokmax!metnet!cmaidt . . . postmaster%metnet@uokmax.ecn.uoknor.edu . . . cmaidt%f9.n147.z1.fidonet.org@uokmax.uucp . . .
