Are they *any* IDE/EIDE drives which don't do sector sparing? Isn't it part of the spec? > 3) Anyone who has sector sparing off on their SCSI drives so they > can use spindle-sync with a ccd driver without losing rotations, > so they have to substitute BAD144 or similar software sparing. I doubt many folks who go throught the hassle of bad144 to get a few percentage points. It's cheaper to buy faster disks. :) > I can think of serveral more rather esoteric applications. > I do know that #1 in my list has personally bit me both at WSU and > the UofU during FreeBSD installs (both were recipients of AT&T > educational grants and now have a lot of old hardware). Hmm, maybe it's a Utah thing, but none of the computers in the Montana University system have ESDI disks anymore. :) Nate
