That's usually the sign of a dying drive. When the drive fails to read
a part of the drive, it will recalibrate itself and attempt to re-read
the data.
As I said, I've put together systems for ten years, and I know what a dying
drive sounds like. This sound is not that kind of sound. This is the heads
parking and then restarting. I can see it, for example, if I load a large
sound file into Sound Forge. The progress bar is smooth until the
CLUNK-DINK, then it stops, then quickly continues. No errors.
I've heard that happen with Maxtor drives, as that's the only brand
drive I've had fail when in service. Try running a diagnostic test to
search for bad sectors, such as Hitachi DFT or Maxtor Powermax. Though
the latter is more likely to say that the drive is fine, if you want to
get a replacement drive from Maxtor you will need an error code from
Powermax.
Yeah, Powermax had no errors on several different machines---Asus A7V333s,
Asus A7N8Xs, and two Tyan Tiger 200T (S2505) server boards with DM9 6Y060P0s
running in mirror. Same CLUNK-DINK noise, but only occassionally, and only
when opening a large program or file.
I've avoided Western Digital in the past year or so because of bearing
problems, and I've avoided Seagate because of head problems. So leave it to
Maxtor to have the best bearings in their recent drives, but not to allow me
to use the acoustic management utility they had a year ago. I'd rather give
up some performance than listen to hard drive noise that should be
*diminishing* with denser platters.
Oh, also if you're running an NT-based OS you can check the event viewer
for error messages regarding the drive. If the drive has bad sectors,
there will be error events indicating that.
Of course, the event logs show no errors---not even warnings.
Maxtor has offered me an RMA on any drive less than one year old, so I'll
probably take them up on that for a few drives.
My own A7N8X-based board is the one I'm wondering about. I may now go with
either an 80GB SATA WD or Seagate drive. I've been reading that the latest
WD drives have LOUD bearings, which still makes me wonder about their
longevity. On the other hand, Seagate SATA drives need those stupid power
cable converters (why???), and I'm still not convinced of their
reliability...
Decisions, decisions...
