HP C1537A Tape Drive - Hardware Compression

Hi i have a HP C1537A Tape Drive with the latest Firmware updates on it, i also have the HP diag tools installed aswell.

Is there anyway to tell if hardware compression is enabled? Or to enable to disable it?

Thanks

Hi John,

Compression is controlled by DIP switches located bottom of Drive.
This link has good info about your query.

Run the compression test within LTT ???

Re: HP C1537A Tape Drive - Hardware Compression

I ran the HP Library & Tape Tools Test Functions on Data Compression Test and the following message box popped up:

Data compression is currently DISABLED within the drive.

[OK]

Then when I press OK on the message box another pops up saying:

Do you want to ENABLE compression before proceeding?

[YES] [NO]

I press yes and the test starts to run then about 5 seconds later it comes up saying it has failed.

I look in the test results and i got the following:
