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:

Hi edv,
This bug was reported a while ago and there hasn't been any activity in it recently. We were wondering if this is still an issue? Can you try with the latest development release of Ubuntu? ISO CD images are available from http://
If it remains an issue, could you run the following command from a Terminal (Applications-
apport-collect -p linux 317858
Also, if you could test the latest upstream kernel available that would be great. It will allow additional upstream developers to examine the issue. Refer to https:/
Thanks in advance.
