A new WD5000BPVT was installed in a laptop three days ago. The drive uses advanced format technology. It is loaded with the Windows Vista SP1 OS. No separate formatting was done by me. OS was installed using the Vista DVD in the default way (which perhaps formatted the drive during installation).
The drive clicks regularly at 5 to 10 seconds interval whenever the computer is not accessing the data on the drive in a burst mode. By burst mode, I mean large data transers, for e.g. file copy, or WD Data Life Guard Diagnostic Tools extended test etc.
Sometimes it clicks more frequently at about 2-3 second interval and sometimes slowly at 1 min interval.
The S.M.A.R.T values reported by WD Data Life Guard Diagnostics Tool v 1.24 on third day of use are shown below. It can be seen that within three days of use the Load / Unload count value has dropped from 200 to 199.
I spoke to the WD Warranty and General information department about this. They say if the drive is faulty they will replace it. But since my drive is servicing the data correctly (without any flaws), I did not say that it is faulty. On being asked about specifics of S.M.A.R.T values they are not aware of the “internal details” and say that they would try to find it (but it does not look to me that they would be able to, since apparantly they do not have a direct contact with the engineering team).
The clicking looks like the head parking issue to me. See WD Green head parking issues. Though that post is about the Green drives, some other places suggest that the drives series ending with “PVT” are power concious drives and use intellipark head parking.
I request to provide me a tool to modify the behaviour to reduce the aggressive parking as soon as possible.
I purchased the drive after being happy with the performance of WD2500BEVT, which do not have these clicking noises - it ran for more than 5 years and its Load/Unload count value is still between 150-180. I would be happy if this drive also can also give that kind of life. At the current rate the Load/Unload Count will drop to zero in less than 2 years!
