Hi Bill. Thanks for the information. I've done a lot of searching
regarding this problem and have since seen that info. Unfortunately,
I have a Cavalry drive, and sdparm reports things like this:
# sdparm --clear STANDBY -6 /dev/sdd
/dev/sdd: Generic External 1.04
change_mode_page: page offset failed: given response length too small,
offset=4 given_len=4 bd_len=0
I assume my brand isn't known by sdparm or doesn't speak the right
protocol or something. So I've had to resort to workarounds like cron
jobs that fiddle with the disk.
I'm sure your post will help some poor Seagate user, though!
