Bug Description
I have clear install of Ubuntu 8.10 and Western Digital My Book Studio II with NTFS connected via FireWire through
01:08.0 FireWire (IEEE 1394): VIA Technologies, Inc. VT6306 Fire II IEEE 1394 OHCI Link Layer Controller (rev 46)
When Gnome session starts it properly mount external drive. If you won't access My Book it may "stand by" after some time.
When My Book is "stand by" and you will shut down PC, My Books filesystem will not properly unmount and it cause data loss.
(Because it didn't spin up before PC shut down)
The Western Digital FireWire disks have some non-standard power savings features which WD apparently tested only with some Windows PCs without care for compliance to the SCSI specs or IEEE 1394 specs.
Are there any messages in the system log from when the system tries to unmount the disk, e.g. SCSI errors? (I am not a Ubuntu user myself, hence don't know into which log file you should look. It is typically /var/log/messages.)
What happens if you manually unmount the disk after it went into standby? Does anything interesting appear in the output of "dmesg" then?
