Ubuntu 16.04, Bacula 5.2.6, single-drive autoloader, all running Bacula
trouble-free for years.
Four months ago I got some errors in Bacula that looked like h/w errors,
although jobs using tar on the same drive ran without error. I had suspicions
about a cable, and when I replaced it everything returned to normal, until now,
when I'm getting the same kinds of errors.
The relevant part of "messages" is:
= = = = = = = = = = = = = = = = = =
05-Jun 09:17 xxx-sd JobId 794: Error: block.c:577 Write error at 12:60511 on

As you can see, it had an error after about 64GB (of an 800GB native / 1600GB
compressed tape).
I've cleaned the drive. And again, backups made with tar record without error
and restore without error.
Any ideas?
