C6280F only 22GB?

Hello,

I have a C6280F HP Surestore DLT4000 Autoloader for 6 DLT with one drive.

I have connected this drive to a Netserver LH Plus running Windows2000. The drive is shown as a Quantum DLT4000.

When I use Backupexec for backing up only 22GB are backed up. Then I have to change the tape. Used taped are designed for 40/80GB.

Do I have to use a different driver for Windows2000?

Bios is updated to 126.

What can I do to backup 40Gb to one tape?

Thanks for help.

The DLT4000 can store 20 GigaBytes uncompressed on tape - that's the recording limit. 40 GigaBytes would mean a 1:2 compression ration. If your data is pre-compressed, the tape drive's software will not be successful.

DLT4000 drives can do 20 GB uncompressed
DLT7000 drives can do 35 GB uncompressed
DLT8000 drives can do 40 GB uncompressed

Easy rule of thumb
