NTBackup cannot compress data with DAT C1533A

Hello

I'm trying to copy over 5GB of data in a tape DDS-2 4/8. It is C1533A.
I use NTBackup in a Windows 2003 SP2 Server.
I put hardware compression in the task of NTBackup and I have the dip switches in DAT ok.
All in ON and the dip 3 in OFF.

I can't copy 5GB, + or -.
The task finalize and in the log can I see that it finalize in 2GB, + or -.

I understand that tape don't compress data.

The Task in NTBackup have "/hc:on" option. Hardware compression active if tape support it.

I tried combination of dip switches and other forms.

Can you help me?
Always Thank you

Karl

Sorry to all.

I've been doing copy of not compresible data.
Tape cannot compress not compresible data.
If I do it with compressible data, the copy is possible.
There is not error in NTBackup.

Bye
