You may want to consider replacing the IDE cable. The CRC errors make me suspicious that it may be bad. The "sector not found" errors may be a side effect of data corruption pointed out by the CRC errors.

It looks like it's done automatically on your computer. What kernel is this? If you're using 2.4.x or 2.2.x with Andre Hedrick's IDE patches this is done automatically. If you have the hdparm package installed you can check this with hdparm /dev/hda as root. Example output on one of my PII systems running kernel 2.4.9 would be: /dev/hda: multcount = 16 (on) I/O support = 0 (default 16-bit) unmaskirq = 0 (off) using_dma = 1 (on) keepsettings = 0 (off) nowerr = 0 (off) readonly = 0 (off) readahead = 8 (on) geometry = 8374/16/63, sectors = 8440992, start = 0 > BTW II: I also see in dmesg the following - does this really mean > there is only 256k L2 cache?? Even my G3 macintosh from 2 years ago > has 1 MB !! This is a 800Mhz Athlon. This is an Athlon Thunderbird, correct? Then, yes it it has "only" a 256kb L2 cache. There are lots of reasons why a 2 year old G3 Mac has a 1 meg cache and the Athlon has a 256k cache, all of which are irrelevent given the difference between the CPU architectures. Phil
