It sounds like it's constantly seeking something. I can't tell from ps -ef what process is making the noise. I've read posts about performance issues with this hard drive. But still I don't know if the noise is a symptom of performance. I don't have much running except firefox. The noise just does not stop! Can someone please clarify? |
Run 'smartctl -A /dev/sda' or whatever the drive name is and post the output. You will need to use sudo.

Hmm, well it looks like SMART is not setup right or smartctl doesn't support this drive, so that won't help diagnose the noise.
What does the noise sound like ? Is it like a regular reading and writing noise ? or is it high pitched ? etc. In many cases a HDD makes a high pitched noise when it is getting old or will fail soon, so I would also run a standalone diagnostic utility like amani suggests, you can try: http://ubcd.sourceforge.net/ |
Try the tool...
WD seems to have a HDD utility that you can use to check the disk. Is your HDD one of these? http://support.wdc.com/product/downl...id=608&lang=en |

Well a few days of using this drive went by, and I finally got fed up! I bought a WD black 1TB, thinking that the higher RPM (7200 as opposed to 5400) would actually make it noisier. But this drive is so quiet by comparison! I won't go back. There's something really wrong with that drive. Maybe I can use the green drive in a backup enclosure when I get one. I learned a lot from this forum, since I never used hdparm before. Thanks everyone, I think I'll stick with black!

And, I believe the 'green' drives are 4k sector and the 'black' are not, which does strongly suggest that the 4k aspect is involved somehow. IIRC, there is a jumper on the 4k drives to use some kind of backward compatibility mode; that might (or might not) help, and you may, or may not, have to re-run the partitioning after changing the jumper state in order for it to work. See here or here for more technical info on dealing with slowness caused by 4k sectors, which may or may not help with noise (but I'm guessing that it will, and, if you still have the drive, would be interesting to try, but it is a guess). |
As you say, "There's something really wrong with that drive"!
I have a couple of WD Green drives (a 320 and 640 GB). They are almost inaudible and they have a rich S.M.A.R.T. feature set; you may simply be unlucky. WD have produced differently constructed Green drives under the same model number, even under the same revision number. They only way for an end-user to identify them is by visual inspection. Details in this silentpcreview thread. |
Hi,
I've not experienced a problem with a 'Green' drive. I've only used them on lower end systems but still not noisy. @OP: The vbcode tags # or quote would make your long lists & data outputs cleaner to read within your posts. It also makes things easier when we are moving between the posts to aid in diagnosis. You can use the WD diagnostics to aid in diagnosis. Along with the UBCD you can look at SystemRescueCD that contain diagnostic & recovery tools. :hattip: The above links and others can be found at 'Slackware-Links'. More than just SlackwareŽ links! |
