Hello all. I asked this question a while ago on another system, but didn't 
get a decent answer at the time. So, here goes.

I have a 70 mb 28ms full height Micropolis 1330 (I think, or 1335) hard 
disk. It currently has an MFM controller. I was told by a couple of 
individuals that it would be safe to RLL this drive (to about 110mb, I 
think), and a couple of other people told me this drive could NOT be safely 
RLL'd. I'd like to know the "real" answer. I called what support Micropolis 
had here in Canada (not much) and only recieved a very vague answer. So can 
someone give me an authoritative answer? The drive has no errors on it at 
all (I've checked it with a couple of programs) and is about 2 years old 
(possibly older, I bought it used). The drive is constantly full, and I 
could really use the extra 30 megs.

Thanks.
