I didn't had this problem before, recently I bought a SSD and installed Windows 7 x64 on it, and now the DVD sometimes spins without reason, it has no CD in it (this makes a bit of a lag).

EDIT:

it usually spins when I start windows explorer, or some other action that probably involves exploring windows folders (starting winamp also could spin it)

saving a file (in ms word ctrl+s) can also spin it

I cannot think of a time ever when my optical drive "spins" or makes any spinning noises without a disc in the drive, even when performing an operation that relies on the device. The drive itself (without OS interference) detects and spins up when there is a disc. Perhaps the drive's disc detection mechanism is malfunctioning. –  horatio Dec 30 '11 at 18:54

p.s. by way of expanding the comment, one can connect an optical drive to 12v power without any motherboard connection, insert a disc, and it will detect and spin up. I once did this as a joke with an old CD ROM drive and PSU, connecting the CDROM headphone out to speakers and used it as a CD player. Your drive may be erroneously signaling to the OS that there is media inserted, and then Explorer attempts to enumerate the volume info. –  horatio Dec 30 '11 at 19:05
    
I have the same problem with Windows 7 x64. I've disabled my CD/DVD drive via Device Manager but it still randomly becomes active for a few seconds. How can I permanently silence it (short of physically tampering or removing it) –  buffer Mar 24 at 7:18

Some likely causes:

Drives set to sleep

In the power settings for Windows, choose the option to not put hard drives to sleep. That has been reported to also effect the optical drives as well.

Anti-virus set to scan on certain events

Your A/V program might be set to perform scans on all drives, including the optical drive. Tinker with those settings and see if that's the culprit. Then determine if you want to continue to have the A/V program scan optical drives. You might want to put up with the random spinning if A/V is doing it.

It might also be set to perform some kind of pre-scan on any drive that is accessed. If a program needs to discover all filesystems connected to the PC, perhaps the A/V program is doing an activity scan of some kind.

Firmware update needed

Check the manufacturer website for your optical drive. It may be that there is an updated firmware for the device that will take care of this behavior.

It sounds like whenever it spins up, it is due to an action that you're performing. For example, if you go to My Computer and wanted to see what drives you had listed, the DVD drive would spin up. It does this for a few reasons. If it case a custom icon then it will need to spin up to display it as it has to read from the disc. Also, if you did happen to want to explore the contents of the Dvd drive then it would have to spin up. Windows is probably spinning up the drive in advance invade you do go to that drive. It is similar to hard drives that have a spindown mode. Usually it will take a few seconds in order to spin up the hdd to access your info. Same concept, but the rotation of the dvd drive is louder and more noticeable.

I don't have any cds inside it, and it sometimes spins when I enter some random folders (not "My Computer"), or when I start winamp –  Omu Dec 30 '11 at 17:00
    
WinAMP can play CDs and could be the same concept. With no disc in the drive, does your computer show that it's empty or does it look like there is a disc in the drive? –  kobaltz Dec 30 '11 at 17:43
    
it shows empty, btw saving a file (just ctrl+s ms word) can also make it spin –  Omu Dec 30 '11 at 20:18
    
I'm not too sure if your problem is related to the SSD. It could have been a Windows update or something that was not previously installed. Have you looked up your model of the drive to see if there is a firmware update available? –  kobaltz Dec 31 '11 at 5:41

Your computer randomly trying to access removable media sounds like malware trying to copy itself to a writable DVD.

Things you can try:

  1. Perform a malware check (e. g. with Malwarebytes Anti-Malware.

  2. Boot on safe mode and run HijackThis to search maually for unwanted start-up items.
