...I need some help in answering a question about the RLL controllers !!

...One of the guys I work with had an Everex 392 RLL controller which

...My question is this:
...
...I was told that the RLL controller will work fo about a month and then     
...will destroy the media which is not coated thick enough. Is there any
...truth to the matter. I have talked to Everex in Freemont, Ca. and they
...will not give me any answers one way or the other. They will not comment 
...past the standard retorek "we support the ST238, if it works on a ST412
...we know nothing". Seagate has no comment at all.


Your data is living on borrowed time!  Any medium which is not certified
for RLL will eventually fail (unless you are VERY lucky!) because of the
demands an RLL controller makes on it.  The horror stories told on
CompuServe were enough to convince me to stop using my Adaptec
controller with an ST-225.  People have reported that they were not able
to reformat their disks with their MFM controllers after abandoning
RLL!!  This is not to castigate RLL, but an RLL controller needs a drive
that can handle the storage density and waveform requirements.
