Noisy when reading CD/dvd's [solved]

Hi all,

I wonder if there's any simply solution to a dvd-burner that's very noisy when it's reading cd/dvd's? It seems the drive spins at its maximum (reading speed: 48x (CD) / 16x (DVD) and it's so noisy I can't focus on anything else. When burning, the noise isn't that obtrusive...

Hardware is Sony NEC Optiarc DVD±RW burner AD-5200A.

Is drive properly mounted in the case (all screws in place, nothing that could transfer the vibrations touches the drive)? Is your box touching some furniture (specifically big empty boxes)? Is it noisy with all cds/dvds or only particular kind?

Try eject -x 16 /dev/cdrom, or whatever speed you want. 0 is normal.

@ TheBodziO - Yes, the drive is properly mounted. It's not a vibration noise I'm hearing, at least I don't think so. It's rather the high speed noise.

@ FALK -  The eject command didn't help.
The available speed seems to be a single one:

eject -X /dev/dvd

48

It is a vibration noise but I wanted to check where it is (there was a chance that it was external). If there wouldn't be vibrations there woudn't be a noise. I would attribute this noise to some glitch in drive motor or bearings that manifest itself on higher rotation speeds (since writing is OK and reading not). I presume that it appears regardless of used media so this should be it… I think that there are two solutions: speed drive down (see hdparm's -E option for this) or get a new drive. Speeding down has an apparent drawback but at least your nerves will hold a bit longer .

Ah, 'hdparm -E 2' did the trick! Thanks!
The settings disappear after a reboot but I can live with that.

Happy to hear that!

You can add your hdparm command to /etc/rc.local to make it run each time you're booting to multiuser (basically every time )

Thanks again. I totallly forgot about rc.local (I checked and it's where I have the configuration for minimizing the load cycle counts for my harddrive).  ^^

Hm...

It seems suddenly the hdparm setting is lost or not executed properly.
My /etc/rc.local looks like this:

/sbin/hdparm -E 2 /dev/dvd >> /dev/null

Worked flawlessly until recently when I wanted to check out a dvd movie.
It spins crazily fast, 48 x.

Setting the speed manually, hdparm -E 2 /dev/dvd, confirms the new speed has been activated :

[root@myhost ~]# hdparm -E 2 /dev/dvd
/dev/dvd:
setting cd/dvd speed to 2

But $ eject -X /dev/dvd reveals:

48

Downgrading hdparm package to 9.21 version and using the manual command helps, but doesn't survive a reboot.

Funny. Any ideas?

Thanks.
