What kind of symptoms can one expect w UDMA on a 2.0.xx kernel like 2.0.29?...
I have a couple of them, a 5G and a 3.3G, both new Maxtor's.
The 5 (>10K cyls) seems useless since simple copies to it couldn't be read. So its in storage till I upgrade the mb as its cyl count exceeds the mb's max. However, since linux doesnt use the bios I expected it to work... surprise. (mb is a micronics M54HI+ w 8300(?) cyl limit)
The 3.3 (>6k cyls) is ok, up to about cylinder 4600(?), which is where mke2fs failed making a new partn. The rest of the 3.3, cyl 0 to 4599, is fine and services both Linux and NT4 just great.
Does this seem consistant w "UNRELIABLE"?
