DAT 24 USB (C1537A) hardware compression

[Matthias Henze]

hi,

i've discovered that my DAT 24 USB does NO hardware compression with linux. how can i enable hardwarecompression? i've tried:

mt -f /dev/st1 compression 1

without any success.

TIA

your drive will do self compression. The expected ratio is 2:1, however, file types and other factors can prevent the drive from doing this ratio.
Compression should be unselected in back up software, this often confuses drives...

See doc if this setting applies to your drive:

Hi i have the same problem with windows 2003, i have checked my software and software compression is off. Where to find the dip switch on the usb model. I got only 12 gig and i backup word, excel, emails documents... Please help we talk about the usb model not the internal one.
