[comp.sys.ibm.pc.misc] Formatting MFM driver with RLL controller. Reliable?

lee@gdc.portal.com (Seng-Poh Lee, Speedy) (03/12/91)

Hi,
I know this can be done, I just want to know how reliable it is.

I'm talking about formatting an MFM drive with an RLL controller. I have
a very reliable Hitachi MFM drive that I want to format in RLL format (need
more disk space). I'd like to hear from people who have done this about
long term reliability. I want to be able to run Xenix 386 on this system. Does
anyone knows is Xenix supports RLL's 26 sector tracks?

Thanks
