Public bug reported:
I have an external Western Digital MyBook 320GB hard drive connected to
eSATA. When the drive is idle everything seems to be all right, but as
soon as I start writing data on the disk, I keep getting errors in my
syslog. Additionally the drive itself makes an audible noise, as if it's
rebooting itself. This happens quite alot when writing to the disk,
sometimes a few times in a row. Nevertheless, the disk hasn't broken
(yet?) even though I've suffered this problem for over an year now.
(Yeah writing a bug report takes so much time...)
I've also tried 2 different eSATA cables, 2 different ports and several
internal ports, none of which removes this problem.
Attached is some relevant info.
The error itself is usually as follows:
