I just got a new laptop and I've noticed that every 10 to 20 minutes, the BD-RE drive emits sounds. The sounds are similar to sounds made by movement of the optical head inside the drive. If there is a disk in the drive, the dive will spin it up in addition to moving the head.
NOTE: Sounds can be heard even when there is no disk in the drive. As I mentioned previously, the when there is a disk in the drive, in addition to emission of sounds, the disk will spin up.
This is the first time I've encountered something like this, so I don't know how to proceed.
I did read this question, but my case isn't as severe, because the optical drive seems to be working normally, except for the intermittent sound it makes.
The computer itself is Toshiba P50t-B-10T running OEM installation of Windows 8.1 64 bit and the drive itself is MATSHITA UJ272 (Panasonic UJ272 in non-OEM versions).
