  sixhub has been running a 251 RLL for over a year. I do not suggest
running a 251 as the 2nd drive on an Adaptek controller, but not because
of format problems (long story). With the WD1006VSR2 I have had no
trouble. My wife has not seen any problems with this, either. She's been
running a systems house since S100 was new tech (1978).

  While ANY MFM drive can fail with RLL, I have never seen the problem
you describe. They usually die within a day or run until they die of
natural causes. Obviously every drive has a finite lifespan, no matter
how it's used.
