Question: We set the device fromat to be 'DRIVE' which means use the highest
format that it supports, does it mean it uses HW compress? Form the 'q vol'
output, it seems it uses as 40GB. How do we 'turn on' the HW compress if it
is not compressed? Thanks in advance for your help.
Best regards,
Phillip Guan
