Public bug reported:
The problem is with external WD USB2.0 hard-drive:
http://www.wdc.com/en/products/products.asp?driveid=219&language=en
Running Ubuntu Gutsy.
When connecting the drive for the first time, all works great. If I keep
using it (reading/writing) - no problems at all. But If I stop accessing
it for some time (1-2 hours), it unmounts itself, without any warning.
before connecting the drive:
$ ls /dev/sd*
/dev/sda /dev/sda1 /dev/sda2 /dev/sda3
after connecting it:
$ ls /dev/sd*
/dev/sda /dev/sda1 /dev/sda2 /dev/sda3 /dev/sdb /dev/sdb1
the next lines appears on /var/log/syslog after connecting the drive:
