I'm want to try setting the "quiet mode" of my SATA drive. When I execute "hdparm -I /dev/sda" part of the output states

Quote:

Recommended acoustic management value: 254, current value: 0

This means that acoustic management is turned off. However, when I try to only query the acoustic mode I get:

Quote:

hdparm -M /dev/sda

/dev/sda:
HDIO_GET_ACOUSTIC failed: Inappropriate ioctl for device

This does not leave me feeling confident that trying to set the value via hdparm is safe. Does anyone know if using hdparm to set values on a SATA drive is safe, or if there is a different utility for sata drives? I'm on R5D1. Thanks!

Marc

I don't know the answer to your question, but oddly enough I got the same error the other day when I tried to set 32-bit mode "on" for my drive. Mine is a PATA drive with one of those little SATA converter boards on it, so I wrote it off to weird hardware. Now I'm wondering if hdparm works on SATA drives in general.

I've read various things about the usability of hdparm w/ SATA drives, all of which leaves me feeling that the answer is "it depends". I'll keep digging.

I (thought) I saw a reply from TJC about trying out smartctl, but I don't see his post anymore. Not sure what happened there, but I tried out smartctl as it's already installed on R5D1. I am able to use smartctl to query the drive but I can't find a way to set the acoustic management setting with that utility. To get it to report back stuff I had to use the "-d ata" flag.

I killed my earlier post since it didn't contain any useful information. Seems that smartctl doesn't work on SATA drives (at least not on my WD5000KS-55MNB0) and searching didn't turn up any obvious alternatives.

Glad to hear that I wasn't hallucinating :-)

Actually, I think you were right the first time that smartctl will work with SATA drives. The issue I had was that I can't find a way to change the acustic parameter with it. FWIW -- here is what I get when I query the drive:
