    Hard drive parking loudly? How to prevent?


    I'm running FC 7 and have a Western Digital Caviar hard drive. At various times when the HDD is used, it makes a loud 'clunk click' noise. The noise is definitely coming from the hard drive itself.

    I found some information on WD and parking the hard drive. Apparently their drives park a couple of different ways - when the OS tells them to, and when the drive's spindle slows down, like it would when experiencing a sudden acceleration. (Like being dropped.) I suspect the noise is the drive parking and unparking itself in a hurry. Here's my two questions:

    1. Is there a way to tell the drive to park, thus confirming the source of the sound?

    2. Is there a way to adjust the parameters used to park the drive, so it will park gracefully and quietly?

    Is the drive getting old?

    I'm guessing that it's getting ready to go out on you. Better make some backups.

    Not to dodge your questions, but these types of sounds from a hard drive frequently indicate that it is failing/dying.

    You might consider installing the SMART tools to run an analysis of the drive. (There is probably a package available in one of the Fedora repositories -- I'm not sure.)

    The drive is fully functional. I received the computer secondhand, and it has done this since I first plugged it in. The Fedora Core 7 installation went fine, and I have used it quite a bit since, with no problems.

    Is that the result of a long test (Extended Self Test)? If not, run that too.

    If so, I'll admit I am a little surprised. Keep us posted if/when that drive dies.

    (I don't have answers to your original questions though.)

    I ran the long test. Here are the results (first entry):

    SMART Self-test log structure revision number 1
    Num Test_Description Status Remaining LifeTime(hours) LBA_of_first_error
    # 1 Extended offline Completed without error 00% 196 -
    # 2 Extended offline Completed without error 00% 0 -
    # 3 Short offline Completed without error 00% 0 -


    No disk problems found, as I said. The sound isn't a disk-shredding-itself sound, it's a part-slamming-into-place kind of sound. I'm thinking it's the head arm hitting the case too hard, either because it is being told to park the heads in a hurry, or the self-protection mechanism is getting activated.

    What utility could I use to adjust drive parameters like this?

    Well, I've managed to answer part of my own question. I discovered that the hdparm command can be used to force a drive into standby or sleep mode. Sure enough, if I issue a -Y (sleep) or -y (standby) command, the drive goes 'clunk', and when it reactivates, it goes 'click'.

    So, back to my second original question:
    Is there a way to adjust the parameters for *how* the drive goes into sleep/standby mode? Such as adjusting the deceleration rate of the spindle, for example.
