On my TS251+ I cannot use HDDParm -M to see what is the AAM setting for the HDD (which is TOSHIBA HDWQ140 FJ1M 4 TB). The drive is very loud and I have to do something about this - so I'm looking to use HDDParm to silence the thing a bit (go to 128 setting, to avoid spin down) - details: https://wiki.archlinux.org/index.php/hdparm.
So, currently I get this error (ssh'ed as admin to device):
Code: Select all
HDIO GET ACOUSTIC failed: inappropriate ioctl for device
Problem is, I don't know the current setting of AAM or how to change it, and I am a bit afraid to connect it to my desktop PC (so that my data does not go to **:)) just to check it and change it. I'm already using SSD as cache, however still the noise e.g. during backups is ** up (I don't get why QNAP couldnt add some rubber to collect the vibes, but nvm).
Does any one know how to get the hddparm to work or what can I use instead?
