Some stuff works in sg_ses, but most is ignored.

The fans are actually pretty quiet by themselves unless the disks get hot and then the fans ramp up and get very noisy.

sg_ses /dev/sg39 --index=coo --get=speed_act
530

sg_ses /dev/sg39 --index=coo --get=speed_code
7

sg_ses --index=coo /dev/sg39 --set=speed_code=3
should have lowered the speed but had no effect...

I was able to set a few values like stop the numbers on the back from flashing, but not change the numbers or turn them off, so just put black tape over them :D

sg_ses --index=dis /dev/sg39 --set=ident=0
stops the very bright numbers flashing

use -ee list the gettable and settable codes

sg_ses /dev/sg39 -ee
