Microport, and Bell Tech both supported a max of *56* bad sectors on an
entire disk. The number in mkpart(1m) is given as 62, but everything
blows up if you get past 56. (I found this out as I was going thru 3
ESDI controller cards, trying to get a Maxtor 4380E to run under
Microport). Interestingly enough, the man page for V/386 3.2 mkpart(1m)
still indicates that 62 is the max, in spite of the "automatic" bad
sector sparing.
BTW, I wound up with a DTC 6280 controller with my Maxtor (128 bad
sectors 8-( ), and it works great, though I'd recommend not using uPort's
mkpart to add or check on bad sectors; it starts scribbling all over the
place and trashes the root file system beyond recovery. I made it
non-executable, just to keep myself from making a mess again 8-).
Disclaimer - I'm just a user, don't work for 'em.
