I have a WD Caviar Green 1Tb HDD, around 2 years ago. It was the data drive in my desktop computer, when I upgraded I took out and put into an external rack and I'm using to carry data.
After several weeks, the HDD started to work "alone". I mean, it can be heard clearly that it's writing or reading, at least the head is moving and makes periodically a series of movements. Around 2 movement groups in a second. After doing this 5-10 minutes, it goes silent. If it's used (I read or write something), it does without delays.
It's definitely not software. If I safely remove from the system, the HDD continues to work alone. Even if I unplug the USB cable and I leave only the power supply cord.
First I thought it's caused by bad sectors so I wiped the drive by writing zeroes (a diagnostic tool from WD site). The same.
This wouldn't be a big problem if I don't hear my second HDD doing the same.
In the desktop computer now I have a WD Caviar Black, 1Tb and the other day I copied some more data by accessing randomly a lot of files so the HDD head moved a lot. When finished, this also started to work alone. (Note that when I analyzed the disk activity with the Resource Monitor (Win7 x64), there was absolute no usage of the HDD). After doing his job, the HDD went silent. Nothing after that.
It is possible that WD has some king of 'self-maintenance' or 'bad sector discovery' or 'built-in defragmenting' system? Or simply the HDD is just too tired? Or it's going to break down?
