write_dma error

[mac.tc]

hi, can anyone tell me what this message is related to?

WRITE_DMA UDMA ICRC error (retrying request) LBA=62939519

drive/hardware failing?
i am seeing a lot of it lately on a particular disk where i have tried a few
different installs and don't always
get this problem. i have seen it disappear after some painstaking before a
reinstall this disk, like wiping the whole disk clean before install,
checking geometry is right, but maybe coincidence?
it is a sata300, 7.2 beta1 amd64 and i am thinking there is problem with the
disk, but the error varied a bit with different installs (i.e. whether i see
the error or not)
