Feisty Fawn would not recognize the drive, but I "apt-get upgrade"-d to 
Gutsy which does. The whole drive is one partition. Under Places | 
Computer the drive shows up as "149.0 GB Volume: Backup". If I unmount 
it, it appears as "149.0 GB Volume". To access it through the command 
line, I find it as /media/Backup.

I don't know what "symlink" refers to, so if it was done, it was not 
intentional. :-)

I read some of the tune2fs man pages. I don't see how to run tune2fs on 
just the Backup drive, and I am not convinced that this is worth doing.

Thank you very much for the information, Holger. No problem starting over with 
a clean external drive. In fact, I don't mind fully uninstalling BackupPC and 
reinstalling it again. I have a couple of (probably dumb) questions.


1. Do you mean that there will be two folder trees called 
/var/lib/backuppc, one on the external drive and the other on the 
Filesystem drive? There is a lot of other stuff in /var/lib on the 
Filesystem drive.

2. If so, then do we need the full path (/var/lib/backuppc) on the 
external drive or can we shorten this to /backuppc or /lib/backuppc on 
that drive?
