Hi,
so it happens I have to work with one of those shitty "green" devices
again that think their power management is smarter than me.
Unfortunately, hdparm just does not fly with USB devices, so what is the
preferred tool here?
# hdparm -B 254 /dev/sdb
/dev/sdb:
setting Advanced Power Management level to 0xfe (254)
HDIO_DRIVE_CMD failed: Input/output error
A SAT layer that supports the SCSI ATA PASS-THROUGH command
is required in the device. Some USB external drives (often
from major disk manufacturers) now support that.
A version of hdparm that knows about SAT is also required.
From memory that is from around hdparm version 7.0 onwards.
