HP C7438A 36/72GB internal DDS5 (DAT72)
Drive not compressing using NTBACKUP on Win 2000 Server SP4?

Already
1. Upgraded the drivers.
2. Upgraded the firmware.
3. Checked the compression ratio with HP Storageworks Library and Tools.
2.23:1. So it is okay.

Windows Server 2000 Ntbackup.exe will not compress. At 42 GB it asks for
another cartridge. I have tried using
the /HC:on switch. It is also the default in the script created by ntbackup
when running the wizard.

Solution or suggestions would be welcomed.

Thanks
Wissarut.

I can't find this Hotfix.

ntbackup.exe will compress files only if this function is supported
by your backup drive. If the backup drive has no compression
ability then the /hc:on switch has no effect.

HP Confirm Hardware compression.
3. Checked the compression ratio with HP Storageworks Library and Tools.
2.23:1. So it is okay.

If so then you may have to ring Microsoft for the hotfix you found
in your KB article.
