not sure about the 2nd error, it is probably related to the first.
I encountered the first error when I used IDE cables longer then 18"
on my Promise ATA/100 controllers(non-raid). The problems immediately
stopped once I used 18"(which is the IDE official spec) cables. I
reccomend checking your cables, if they are longer then 18" then
replace them with 18" cables.
This isn't specific to linux, I encountered the same problem under
freebsd 4.4 as well last year. the CRC error is not a fatal error,
just a warning that some data failed a check, the data was transferred
again and it passed the check. You can probably generate a ton
of these errors by generating some high I/O such as looping a kernel
compile or running bonnie++
ditch the 24" or 32" cables if you have em though. In some systems
the 18" cables are short enough that I can only fit 1 drive on each
cable, the 2nd connector doesn't reach..but thats life I guess.
