Hi there,

we had this toic befor and I#m back again...

My Backupjobs started to use less tape space then expected a year ago
the System is quiet aged so this is running on a 2003 SBS with a bacula 
version 3

Like I said it started from one day to the other that tapes got written 
on  but less then the expected 350+ GB for a LTO3 tape. what Ive done so 
far:

  - changed terminator
  - canged cable
  - changed the drive
  - changed the whole autoloader
  - used brand new tapes
  - cleaned drive a dozen times
  - used HP tools to check for problems

nothing really help, in fact its getting even worse. We started with 3 
tapes for less then 1TB and now Im at 6 tapes for 1,2 TB of data. I get 
this line for every Tape that reaches the "end" of the tape or better 
bacula thinks its the end

02-May 17:12 fg-back-sd JobId 11840: Error: Error writing final EOF to 
tape. This Volume may not be readable.
/home/kern/bacula/k/bacula/src/stored/dev.c:1723 ioctl MTWEOF error on 
"LTO3" (Tape0). ERR=Input/output error.

but some post on the list suggest this is normal for a windows 
environement and I got this when all worked well too. The strange part 
is I havent changed any config at all.  since I know some people will 
tell me without logs and stuff there is nothing to tell I will not ask 
for possible causes because we going to change the backup in autmn 
anyway and we will move on from bacula with all the problems we had over 
the last year.

But back to my question, is there any thing that bacula does to mark the 
end of a tape even its not the end? And additional is it possible to 
remove this marker (if it exist possibly in the database) . Like I said 
in my opinion its not passible that 4 brand new tapes have errors 
arround 200GB of written data.

Regards
