As a wild guess, I'd say the USB drive is going to sleep and takes
more time to spin up.  Your PreUserCmd is probably the right idea but
also failing and continuing too quickly.  'fdisk -l' might be better
but needs to run as root, or maybe just adding ";sleep 2' after your
ls command would work.

[BackupPC-users] Tar causing problems with removable drive on localhost

[Adam Hardy]

This is picking up something that I didn't have time to sort out in
October.

I keep getting a problem from tar when backuppc goes to back up the
localhost, which includes a removable drive in the backup targets:

50% of the time, the backup works. When I run the command above as the
backuppc user, it never fails. The removable drive is always
connected. 

Following advice from this mailing list in October, I searched all my
logs and found nothing related. 

I also added this to ArchivePreUserCmd: ls -la /media/adam/Videos-
2TB/Videos 

However the error has not been solved.

Here's the original email in the
archive:

Have you got any more advice on this for me? 

Thanks & regards
Adam
