Hey Guys,

Recently I've been noticing my superdrive making it's "hellooo, any disc there" call while i've been surfing the net and I haven't been able to figure it out.

I've been working the late shift at work - 3pm till 10pm so I get home at 11:30 and relax with my MBP.

Tonight I looked at the clock and it all makes sense, the time was precisely 12:00AM when the sound has been happening, anyone else having this? any explanations?
The only reason I can think of is some cron job that may be running, or some firmware function with purposes unknown.

Try looking into the optical drive in a dark room when it's reading from a disc (eg: an installation DVD) and it seriously looks like one of those Cylon thingys from Battlestar Galactica (the recent edition).

It is quite obviously related to the moment when a new day starts.
As a watchmaker I can inform that a malfunction of date change will always stop a watch.

This is probably some background process.. Do you have "set date and time automatically" switched on? .. in Date and Time prefs pane.

Yep, but I don't know why it'd make the os poll the drive at 12:00 on the dot.

My MacBook used to do it at midnight too, but it stopped happening after I wiped it to put leopard on last month.
I kind of miss it happening.
When I used to hear it, I had a Pavlovian response to check out what the new Item on the Zazz website was.

Could it be on the system scripts running?

My iMac starts chugging away at 12:00 midnight also.

We must have caught the same virus!

Next time I notice it, I will open Activity Monitor and see if I can detect the culprit.

Are you by any chance running Apple Mail at the same time??

It makes a strange noise when there arent any messages.. Sounds sorta like the disk eject sound in a way :)

My old MacBook did this as well, spot on 12:00, no idea why.

this happend to me while running tiger but has disappeared with the leopard upgrade. nothing to worry about. if you look at activity monitor at 12am youll notice teh build_hd_index takes up a little cpu load.

its a left over daemon from panther which indexed hard drives for searching before we had spotlight. theres a command you can use to disable it but it never worked on my macbook pro.

This wouldn't have worked because there were no releases of Panther for intel machines. :/

Probably a service relating to the commandline tool locate, which I actually use :P

sorry i forgot to provide the link for my reasoning and that command http://devnevyn.livejournal.com/3558.html. it was just left over when apple upgraded panther to tiger. apple doesnt rewrite OS X for incremental updates they just add to and refine. the daemon must of been left there but removed in leopard.

Did you update or clean wipe and install?

Updates can leave traces of the old operating system

It's a service in Apple Remote desktop, since all my machines have ARD installed for management it's running this for daily reports.

I've disabled it now.

:D Turning off Set Date and Time Automatically has resolved this problem on my MB. :thumbup:
Thank you!

System Preferences>Energy Saver>Schedule

You've obviously ticked one of the boxes.

LarryH,

If your reply was to pschargel, the problem with my MB doing nightly midnight ejects was resolved by unticking System Preferences>Date & Time>[x] Set Date & Time Automatically checkbox as suggested by AusMac. I have since looked at your suggestion, System Preferences>Energy Saver>Schedule, but found no ticked checkboxes. Thanks for your reply.

My macbook has been doing this as of recent (on the hour, different hours) , not sure if its the superdrive...

I'll try all the above options, (started with the automatic date / time update stuff)

That didnt work :(
