Default USB hard disk ON and OFF

Hi

I have an external USB HD which I labeled AMHD.
When I insert the HD it mounts at /media/AMHD as expected, but every
minute or so the HD umounts and remounts.
How can I avoid this behaviour which is very annoying?

Tx/Alain

I've got several USB HD's (2.5" & 3.5", PATA over USB as well as SATA over
USB) and I've never seen this (although I did have a drive that would "die",
could no more write on it after some time - the HD itself seemed faulty).

Anyway, I doubt this is a Linux/Ubuntu problem, I'd look for the problem on
the drive itself. Can you test it with another OS? Faulty USB connector? How
is the drive powered ? Anything in the logs?

It would also help to have more info, which version of Ubuntu you are
running, updated, etc.

I run Lucid Lynx and I update whenever the notifier says updates are available.

I checked the messages file and found this (hope it is relevant)

Well, I am no specialist, but to me it seems the system itself is working OK.
the problem is that the USB drive disconnects - I suppose that's also why it
has to be checked every time.

I would try to connect the drive to another computer. If the problem remains,
the disk (or it's enclosure) is faulty. If not, then it could be your
computer's USB.
