I have never done this before, so this is just a shot in the dark here, but what I would try is to search the registry for tape0 and if you find the key change it there.

Hi,
Thanks for your replay,

Sreekanth, all of them, the problem here is my USB tape drive is identify by windows with that name :\\.\tape0
I need to change the name with C to the end:
\\.\tape0C
because if Data Protector see the C at the end will active the compression, actually the compression in this tape drive doesn't work.

The problem involve Windows and DP, the tape drive is out to the problem , the tape drive work fine, also I install right drive for HP usb tape drive (HPUSBSMC), the last vercion,
Maybe if I modify someting in regedit can make the trick.(but I don't know what!).

Regards.

What is the model on the tape drive? Does it support hardware compression, or is this something you are trying to enable in the software?

There isn't a C option in the drop down device selection box?

To enable software compression, see here, page 52. (Not recommended) http://h71028.www7.hp.com/ERC/downloads/4AA1-3836ENW.pdf

And for Hardware compression, select the tape devices in the pull down box in dataprotector manager and see if the C device is listed.

Hi Brian

No, doesn't show the C option

"And for Hardware compression, select the tape devices in the pull down box in dataprotector manager and see if the C device is listed".

Don't show the option, the problem is the tape drive should show it , but It dosn't.

only show the option \\.\tape0, for that reason I want to changed the HWpath with the C to the end.
Also , HP replace the complete tape drive and same problem.
If I add the C to the end , the DP active the compression option but when run backup DP doesn't find the path and discovery the new path o real path without C

Thanks
