For some time now I’ve noticed that my WD has begun stuttering occationally. It’s these small interruptions that are very noticeable when streaming from the disk, say playing a game or watching a movie. I can’t describe it accurately, as I clearly don’t know what’s going on, but it seems to me like the the disk has to reposition the heads every now and then, and that leads to the occational stutters which I notice.
There are no errors showing up when testing the drive with WD’s diagnostic tool at all, not even the extended test. Neither when I’ve run other tests, like CrystalDiskMark or HD Tune Pro. The SMART data seems fine too, every disk diagnistic program reports OK next to the smart values.
Like I said, the occational stuttering is very real on this drive, and none of my other drives display this behavior. But if I’m supposed to RMA the disk, I’d like some hard evidence and I’d like to be able to see what’s going on when those stutters occur.
Any ideas on tests that might expose this perceived weakness? And possibly any fix for it?
I’ve noticed the disk operating at 55 C, which is near the 60 C that is specified as the max operating temperature. Could this technically be the reason for the rather occational phenomenon that I’m experiencing?
