Optical drive being accessed (makes noise) waking from sleep & on startup

On my Macbook Pro, the optical drive makes a noise as though being accessed whenever waking up from sleep mode or powering on. Is this normal behavior?

Optical drive being accessed during sleep

I close the lid, put it to sleep and my optical drive keeps being accessed. Its erratic; 1,2 or 3 times a minute - sometimes it doesn't start for 35 minutes, sometimes it stops after a while. No outside devices attached. Its annoying to say the least.
Anyone else have this problem? I talked to technical at applecare several times and they had no record of anyone else having this issue.

I've made some progress. I figured that was happening (and shouldn't be happening) was that something was momentarily waking the computer which does a optical disk access when it wakes.
I disabled wifi and that didn’t do it and then I disabled Bluetooth – I use a Logitech Bluetooth mouse – and that stopped the problem.
Further details if anyone is interested: when I close the computer case and put my mouse on top of the macbook there is no problem. No optical drive accesses. When I put the mouse on my wooden desktop the problem starts. I turned the mouse upside down (case closed – sleep state) and after a while a little red led started blinking in a small window. When I put my finger over the window the optical drive was accessed. The mouse is sending something to the computer and it wakes. It shouldn’t wake but it does.

Noise waking from sleep

is it normal for the dvd drive to make a noise when waking up from sleep?

Yes, in fact I have never had it wake from sleep without making a noise. I think it's something with the drive checking itself or something to that accord.

Workaround for the problem of ultrabay HDD ejecting when waking from sleep

After trying every possible "solutions" with no luck for the problem of the second hard drive always ejecting/disconnecting when waking from sleep in my T530, I've decided to create my own workaround.
This is by no means a definitive solution but a nice workaround that uses little resources on the machine.
The idea is to simply let a program runs constantly from the second hard drive. That way, when the HDD tries to disconnect, Windows is not allowing it and then it stays allways connected.
To make it more thansparent I decided to create a Windows service that starts when Windows boot and stops when Windows shutdown.
This Windows service is very lightweight : it does absolutely nothing and just waits indefinitively.
The trick is that it just have to be started from the second hard drive.
Here is a link to the Windows service, 32-bit and 64-bit, with the source code and scripts to install/uninstall.
Just install it anywhere on the second hard drive (D: in my case).

Works perfectly for me on my T530 with Windows 7 Pro x64.

Hmm, I have no problem with Ultrabay ejecting HDD when waking from sleep mode. At first, I went down the same
route as you did. For the first few days when I received my T530 I kept an .iso file from Ultrabay HDD always mounted.
But then I disabled all power saving options within Windows and Lenovo Power Manager and it seems to work fine.
Works both with Windows 8 (64-bit) and Windows XP Professional (32-bit).

MacBook optical drive has started making noises at wake and restart

This MacBook is about 5 months old and the optical drive has just started making noises at wake from sleep, or at restart. There is no disc loaded in the drive, but the noise is as though a disc has been inserted in the drive and it is attempting to read it. This goes on for about 5 to 10 seconds, then stops.
The optical drive seems to work fine, reads CDs and DVDs no problem. This isn't a glaring issue, I'm just trying to determine if it is the precursor to a mechanical problem, or is possibly some sort of software glitch. Thanks for help if this rings a bell with anyone.

I posted this to a different thread earlier today. I will add that most of the experience I've had with this issue is in Tiger or Leopard. I don't think I've seen it yet with Snow Leopard. My instincts tell me it is more of a hardware issue than a software/OS issue. (Just my $0.02.)
I have seen this many times. (I support 100+ Mac Laptops, most are 13" MacBooks.)
Just to clarify, MacBook optical drives do normally make some quiet noises when waking from sleep.
When there is a CD or DVD in the drive, there are some soft sounds, and then you hear the disc spin up. When there is not a disc in the drive you hear a different sound. I assume it is relating to checking for a disc in the drive. To me, it sounds exactly the same as the quiet sounds you hear right before the "Good Chime" when you power up.
BUT, sometimes MacBooks make a much louder noise, that is similar the sound you hear when you insert or eject a CD or DVD, only sort of "doubled". Usually you hear it when waking from sleep, but I have also experienced it happen intermittently when the MacBook is turned on, under normal use, or not being used (but not sleeping or waking from sleep).
In the past, I have sometime cured it with a reset of the SMC and PRAM. This has not always worked. I have also seen it disappear after inserting a disc into the drive. Most of the time, the sound has returned some time later. I have called Apple on this issue several times, and sent the MacBook in for repair. My memory is that they have replaced the optical drive under AppleCare.
I will add that I have recently seen this Knowledge Base Article (below), with instructions for "resetting" the optical drive on a MacBook Pro, but it did work for me on a MacBook 13". Insert a disc halfway, take it back out, then put it in all the way.
http://support.apple.com/kb/TS2839
Past experience tells me not to be surprised if the noise resurfaces. My advice is call Apple if you have AppleCare, or if the MacBook is under one year old.
Good Luck.

Drive sound when waking from sleep?

Hi, I am getting a short 2-3 second drive sound when I wake my MBP from sleep. It sounds like it is checking to see if there is a disc in the drive or something. Also might be described as the sound when your first put a disc into the drive(but maybe shorter). Is this normal? And also if it is normal is there a way to stop it from making the noise because I actually find it annoying me, I wake my computer from sleep a lot throughout the day. My friends MBP who bought his just a few months before mine does not make a sound when waking from sleep. Thanks.

They all do. All of them. Yours. Mine. Your friend's. Old PowerBooks. Brand new MBPs. Everything in between.

Maybe his optical drive is broken?
Or, more likely, it's not waking up from sleep at all - Energy Saver settings can be used to set the display to sleep before the MBP sleeps - a key press will "wake" the display, but the MBP itself was not asleep, thus no noise from the drive when it the display is reactivated.

Since updating to Lion the iMac won't recognise the external hard drive (maxtor) when waking from sleep mode,

Hi All, Since updating to Lion, my imac won't recognise the ext HDD (Maxtor) when waking from sleep mode, I have tried another port, diisc utility (Ext HDD not listed in here) but nothing works. I now find that I have to restart the imac to get the drive recognised..which is fine until the imac goes into sleep mode then I lose the drive and have to restart etc etc.....anyone suffering same issue. The Ext Drive worked perfectly until the upgrade..

Thanks for this, and apologies for delay in replying...in between seeing your post I backed up the ext hdd to another mac and used the disc utility to erase and repair and then re mounted the ext hdd. OK. I have then tested the ext hdd being recognised when waking from sleep mode a few times and everything appears to be fine. If this doesn't work (long term) I will follow the instructions as you have suggested....
I now have a new problem with my HP printer (Photosmart Plus) which is not being recognised by a new wireless router..Ok whilst the router is switch on and I have reconfigured the printer..but when the router is switched off overnight and then switched back on...I get a 'printer is not connected' message and have to go through the re configure routine all over. I am minded to think this is a router problem as the same issue is happening to my wifes Mac Book Pro (which is only a few weeks old)...any suggestions..

External Hard Drive Fail After Waking from Sleep

Hi,
I've been having this issue for over a year (since upgrading to Lion, and now still persists after upgrading to Mountain Lion), and I haven't been able to find the exact answer I need after searching through the posts here, and on the internet.
I have a 2011 MBP, and after upgrading to Lion last year, I've noticed that my WD external hard drive for the Mac has issues to be recognized after the laptop wakes from sleep. The drive icons are still there on the desktop, and all the files are listed. However, I cannot open any of the files, and Time Machine backup automatically fails.I am able to eject the drives by dragging the icons into the trash can. However, nothing happens if I simply unplug the fire wire 800 cable and re-plug it into the computer after ejecting the drives. I need to reset the external drive by unplugging both the fire wire cable and the power supply, and replug everything.
Aside from being a hampering process after waking from sleep, this is also very stressful on the drive itself, so I would like to fix this. Does anyone know the issue behind this or have a solution? Thanks in advance!

I own PSE 7 on disc. The laptop it was loaded on died. My new laptop doesn't have an optical drive so I downloaded PSE 7 from the Adobe site. It downloaded fine but I cannot start using it until I enter a S/N. The S/N on the disc box doesn't work.

Those links weren't particularly helpful to me. They convinced me to install the drivers for my USB 2.0 card, but that didn't make a difference. Still no OS X without a PRAM reset if I've dared to venture into OS 9.
It's always been my understanding that an unblessed System Folder will not be selectable in OS 9's Startup Disk control panel. My folders are blessed and healthy. Of course I'm running 9.2.2, as stated in my first message. I also frequently verify and repair my disks and permissions.
I did a verbose startup of OS X, and noticed something funny about "ATY...too old." Perhaps this problem is related? I ventured into my system.log file and there it was, repeated over and over, everytime I've booted this computer:
Aug 8 18:30:24 localhost kernel: From path: "/pci/@d/pci-ata@1/ata-4@0/disk@0:10,\mach_kernel", Waiting on <dict ID="0"><key>IOPathMatch</key><string ID="1">IODeviceTree:/pci/@d/pci-ata@1/ata-4@0/@0:10</string></dict>
Aug 8 18:30:35 localhost kernel: ROM ndrv for ATY,Rage128y is too old (0xb3383430)
Aug 8 18:30:41 localhost init: kernel security level changed from 0 to 1
Anyone know how to interpret that? Is it related to my problem? I googled it, and all I found was a web board of people arguing over whether the Apple installed stock ATI Rage video card that came in the G3's is appropriate for Panther. The Ye's have it as far as I'm concerned...as long as I leave OS 9 alone, my video is fine on this computer!

URGENT!Can I user a THIN jdbc driver to access a CLOB field from oracle 8.0.5 DB?

I think you'd need to contact Oracle support to get access to older versions of the driver.
Since 8.0.5 isn't supported any longer, however, is it possible for you to update your Oracle client to one of the supported releases-- 8.1.7 or 9i?

Noise when waking from sleep

I have a G4 iBook 1Ghz, 512MB Ram, 60 g HD, running 10.3.9. When waking from sleep, it has a loud buzzing noise that comes from the speakers. I know it is the speakers as you can silence it with the volume. If you restart, it is silent. It is silent from startup. It only does this on waking from sleep. At times it won't wake up at all, only responding to a forced restart. I've zapped the PRAM, reset the PMU, and all of the sound preferences. Anybody got any other suggestions?
Thanks, Andy Ford

I have this problem too. Sounds like shaking a can with some sand in it. Soft, not really noticeable unless you are in a quiet room or using headphones. Have all sound effects turned off in system preferences.... Have tried muting the volume. That doesn't work.
I also notice that I get the same sound if I do something that would otherwise generate a system error noise (like searching for a term in Safari that is not present on the web page). But only on the first instance. So on my initial search for the term, I get the soft noise. If I do Cmd-G to search again, no noise.
It's strange and I wish it would go away but I have been able to ignore it so far.

On my new iMac, mail has no sound after waking from sleep. If I select do not wake for network access in general preferences, the problem does not occur. Anyone have an idea on how to fix this?

Same here on an older iMac since Lion. Thanks for the uncheck wake for network access tip though, it doesn't do it either in that case, I will leave it that way.

Disk drive thrashing after waking from sleep

Apple conundrum - iMac goes from sleepy to grumpy....
At times after waking from sleep mode, my disk drive thrashes for up to 3-5 minutes. The thrashing almost always includes an SSBOD. Then it stops and things seem fine. My iMac is not backing up as I check for the TIme Machine icon activity. I have also checked and disk permissions and keychain ae fine.
Any ideas on what is causing the disk thrashing.... and how to fix it.
Thanks
Bruce

To find out what the Mac is getting grumpy about, open your Activity and check to see what it's doing those first few minutes.

My macbook pro (lion 10.7.2) takes several minutes to connect to the internet after waking from sleep. Is there any way to make this instant?

Hi
My Macbook Pro 15 inch takes several minutes to be able to connect to the internet after waking from sleep. Does anyone else have this problem and is there a fix?

The message that comes up when I click on "TomTom Home Install" is "You cannot open Home Install because Power PC applications are no longer supported." Does this mean that the TomTom, which is absolutely vital to my life - well, not literally but you know what I mean - can no longer be used with my MacBook Pro?
What that means is that is can't be used with Lion 10.7. PowerPC was the chip Apple used up until 2006 when they switched to Intel. At that point, they created the Rosetta emulator to allow for PPC support for 5 years. They finally dropped the support with the release of Lion. It will only work with OS X 10.6 or earlier. The other option is to purchase a new GPS, which can be had for $100 for a decent one.

Can iMac not waking from sleep be caused be a corrupt file

I have had my 27" iMac from July of 2011 (running Montain Lion, 8 GB RAM, 2TB hardrive, 3.4 GHz,Intel i7) for over a year and a half and ever since I bought it, it has had a problem waking from sleep. I can hear the computer running, but when I click the mouse, keyboard, or power button, it stays asleep and I am forced to do a hard shut down. Apple has been trying to fix the issue, but to no success. They have replaced the hard drive, logic board, usb ports, RAM, mouse and keyboard, but it still happens. They finally threw in the towel and are replacing the machine. They offered to transfer all of our files (jpgs, mp3s, docs, videos, etc), but one thought occurred to me... what if the sleep issue is caused by a corrupt file? I highly doubt that is the case, but wonder if any of the experts out here would know better than I.
If we didin't have the data transfered, we would just keep it on an external hard drive instead. But, I would assume that it wouldn't matter if the files were on internal vs. external because either way, the computer would access the files. That being the case, if the sleep issue was caused by a corrupt file, the computer would still access it on the external and the sleep issue would resurface.
So, 2 questions:
Can a corrupt file cause the sleep issue?
If it is true that a corrupt file can cause the sleep issue, would it matter if the corrupt file was accessed from an external drive vs. internal drive?
Thanks so much!
Chris

Please read this whole message before doing anything.
This procedure is a diagnostic test. It’s unlikely to solve your problem. Don’t be disappointed when you find that nothing has changed after you complete it.
The purpose of the test is to determine whether your problem is caused by third-party system modifications that load automatically at startup or login.
Disconnect all wired peripherals except those needed for the test, and remove all aftermarket expansion cards. Boot in safe mode* and log in to the account with the problem. The instructions provided by Apple are as follows:
Shut down your computer, wait 30 seconds, and then hold down the shift key while pressing the power button.
When you see the gray Apple logo, release the shift key.
If you are prompted to log in, type your password, and then hold down the shift key again as you click Log in.
*Note: If FileVault is enabled under OS X 10.7 or later, or if a firmware password is set, or if the boot volume is a software RAID, you can’t boot in safe mode. Safe mode is much slower to boot and run than normal, and some things won’t work at all, including wireless networking on certain Macs. The next normal boot may also be somewhat slow.
The login screen appears even if you usually log in automatically. You must know your login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin. Test while in safe mode. Same problem? After testing, reboot as usual (i.e., not in safe mode) and verify that you still have the problem. Post the results of the test.
