I have a 71 MB full height Miniscribe that I used for 1 year MFM before I changed it to RLL, and it has been running happily for 1.5 years now as a /usr/spool filesystem on a computer that runs news. I also have a Maxtor 2190 formatted to 244 MB that has been running for 6 months with no problems. Yes, there are problems with some drives, but just because the drive is not rated RLL, does not mean that it will loose data after a month or so. The bottom line is try it. It may work it may not. BTW: I did have a Maxtor 2190 go flakey after 3 weeks when formatted RLL, but I discovered it was flakey when formatted MFM also. The only thing I do differently when using a MFM drive RLL, is I tend to run extra passes through the diagnostic software to make sure I get all the bad blocks before I put data on the drive. -- Terry Hull Department of Electrical and Computer Engineering, Kansas State University Work: terry@eecea.eece.ksu.edu, rutgers!ksuvax1!eecea!terry Play: terry@tah386.manhattan.ks.us, rutgers!ksuvax1!eecea!tah386!terry
