No, I don't solve the problem, yet. - I slow down the Bus-Speed in the
Controller-BIOS for the LVD-Connector from 40 to 20MB/sec. - With this
change, the write-process (backup) now works - but restoring fails...

"cat /proc/scsi/aic7xxx/0"
"aic7xxx" is the module for my AHA2940U2W-Controller. - Another place, where
you could find the the information is in your /var/log/massages-file.

Hmm, nice that Amanda have this "with-broken-fsf"-option. But if I only want
to use tar sometimes..? ;)
First, I've to do is, to speed up the tape. Than I try the
"with-broken-fsf"-option.
