whozurmommy Posted September 27, 2009 Share Posted September 27, 2009 Of course it's not doing it now that I'm writing this post, but I've heard the the last few nights. I often leave my machine on overnight, and last night I could hear it spinning up my CDROM drive for a second or two and then stopping. It does so about every 2-3 minutes.... AH HA! THERE IT GOES! Okay maybe it's every 5 minutes. Has anyone else seen this, or am I just crazy?

Ecco2 Posted September 27, 2009 Share Posted September 27, 2009 That's weird. I'd say that some application, for some reason, keeps polling your DVD. A good test would be to create another user (foobar for instance), logout, and login as foobar. Now tell us if the problem happens again… If not, then it's definitely an app your regular user is running that's the cause of your issue.

I tried your suggestion and it did not work. :-( If anyone else has a suggestion I'm all ears. Is there any sort of log file or process monitor that I can hook to see what process is attempting to access my drive? I haven't installed anything except Xcode.

Braddman Posted September 27, 2009 Share Posted September 27, 2009 Mine does the same thing from time to time. The only way to make it stop is to insert a DVD in the tray. Mine is USB. Right now it's not doing it, so I have no idea what causes it.

Right now it's not doing it, so I have no idea what causes it. I timed it, it was pinging/polling my CDROM every 47 seconds, causing my drive to go "Grr grr grr grr", then stop for another 47 seconds. Very annoying in a quiet room. Anyway you are right, putting a disk in the drive stopped it, but I'd prefer to have a real solution.
