I have a problem with Intel 320 80GB. Several times I have had system freezes (from 10sec to 30sec). I own drive from two months.

I'm using linux.

Controller

I tried with other SATA cable, didn't help.

 

Any help please.

    Drive looks to be in perfect health according to all of the SMART attributes.  Your issue is probably due to daemons running on Linux in the background which are doing I/O to your drive.  dmesg, smartctl, df, etc. aren't going to help diagnose this.  Things like sar or iostat or top -b in a while loop logging to a file might.  Furthermore, you should investigate TRIM support on Linux -- it is something you do have to turn on, if I remember right (I'm a FreeBSD guy, not Linux).

    There's your problem. There are compatibility issues between nvidias fake-AHCI and SSDs. The usual solution is to run the controller in IDE mode and make sure to disable Command Queueing in the driver. How you would do on Linux I have no idea.

    Thanks for replies.

     

    I'll check the TRIM.

     

    Two years ago I had a Kingston SNV125-S2/40GB with Intel's hardware inside but without TRIM support and that issue didn't occur... (the same controller and operating system). What do you think now ?

     

    Maybe it's elevator=noop ?

     

    cat /sys/block/sda/queue/scheduler
    [noop] deadline cfq

     

    I'll check it too.

     

    Beside I forgot to write about the scenerio this issue. It happens (rarely but...) when I unpacking kernel or installing compiled app/package.
