    Re: 9.10 upgrade says I have failing hard drive

    I have the same problem with a Seagate SATA 500GB drive. Just upgraded to 9.10, drive only 3 months old.

    What tests are recommended to determine if this is real or not?

    Please be explicit.

    Re: 9.10 upgrade says I have failing hard drive

    OK I will take a crack at this... The disk utility seems to be causing some panic and may or may not be incorrect depending on your specific hard drive. In reality the SMART implementation of the hard drive matters.

    BASIC TEST:
    1) In disk utility note what the drive path is: as an example /dev/sda
    2) install the smartmontools if they are not already installed
    Code:
    sudo apt-get install smartmontools
    smartctl has a dependency on postfix so it will prompt you on how you want to configure mail. Unless you really want to configure mail properly I would choose none or local. (I have the smart tools email me notifications, but that is not something most people will need.)

    3) from a command prompt and type
    Code:
    sudo smartctl -A <path to drive>|grep Reallocated_Sector
    so in the example of the firdst drive (dev/sda)
    Code:
    sudo smartctl -A /dev/sda |grep Reallocated_Sector
    Note: smartctl -A puts out a lot more information and you can look at it in its entirety by removing the grep. Since this is the particular attribute that is causing a stir I wanted to narrow the focus.

    Now you should get output something like this
    Code:
     5 Reallocated_Sector_Ct   0x0033   100   100   036  Pre-fail  Always  -  6
    The only numbers to concern yourself with at the moment are the last one, the raw value, and the one immediately before "Pre-Fail", the threshold. The threshold will vary depending on the type of disk and manufacturer. Generally 36 seems to be a common number for desktop hardrives. For 2.5" (laptop) hard drives it varies more. An unscientific survey of the dirves in my laptops showed thresholds between 24 and 140.

    - if your raw value is a very high number (over 500) then it is likely not reporting SMART data correctly, get the disk utilities from the manufacturer (see below)
    - If your raw value is over your threshold then you very likely have a problem and the drive should be replaced. run "sudo smartctl -A /dev/sda" and look at the output in its entirety. Additionally you should run the manufacturers disk utilities (see below). This will speed up the RMA process if it is still under warranty.
    - If your raw value is over half of your threshold I would suggest keeping an eye on the drive at least. you might consider trying to RMA it but depending on the manufacturer it may not be "bad" yet.
    - If your raw value is under half of your threshold then the drive is very likely fine.

    Again this is personal experience, not concrete fact, but I have noticed a tendency for Seagate and Samsung Drives to report a few bad sectors on a regular basis. Western Digital however rarely reports bad sectors until the drive is starting to have problems. This may be just the luck of the draw for me or it may be a variation in the way the different manufacturers report SMART data.

    MANUFACTURER SPECIFIC TESTS:
    If you want additional assurance on the status of your drive I would suggest going to the manufacturers site and downloading their disk testing utility. Most will require you to boot into windows but some will have a bootable CD. In reality for the most part these disk utilities will basically be reading the SMART data, but since it is a program from the manufacturer I would argue that they are better equipped to determine the appropriate values for the data.

    Here is a link to the disk diagnostic tool for Seagate:
    http://www.seagate.com/www/en-us/sup...loads/seatools

    This site (once you pick your specific drive) is for Western Digital
    http://support.wdc.com/product/download.asp?lang=en

    To put this in perspective I have multiple fairly large RAID5 arrays. Out of 5 1.5TB Seagate drives I have 3 with bad sectors(1, 3, and 6 bad sectors). Out of 5 1.5 TB Western Digitals I have none currently reporting bad sectors. I do not attibute the difference to WD being more reliable than Seagate but to a difference in the way the 2 manufacturers report SMART. Out of 12 other drives from various manufacturers and size only 2 are currently reporting bad sectors (14 and 9). None of these numbers are high enough to cause me alarm at this stage but I do have mail notification set to monitor the health of the drives so if/when one does approach PRE-FAIL I can replace it before it becomes a problem. Disk Utility is a great tool in that it puts SMART data in a visible element for the end user. But it has the unfortunate side effect of causing panic when the user is not used to seeing errors on their hard drives.

    EDIT: I wanted to add a small editorial on Windows "check disk" chkdsk and other (non manufacturer) Windows disk utilities are pretty much worthless for determining the health of the hardware. What the Micorsoft tools check is whether the file system is intact, not whether the hardware on which the file system resides is intact. In most cases by the time chkdsk would detect a problem caused by hardware failure it is too late. It is for this reason that SMART was created in the first place. It is not fool proof, not even close (check the paper written by Google on the subject), but it does help.

    Re: 9.10 upgrade says I have failing hard drive

    Here is my report:

    Keep in mind the drive only has Ubuntu installed. I have two other disk drives, one for win and the other for my data. If this drive dies, I lose nothing, except a separate disk for Ubuntu, and the MBR, which is easy to fix.

    Anyways, have a look and tell me if disaster as close as Palimpsest and smartmontools says it is. Again, this is for an ATA Maxtor 4D040H2 40GB drive after a zero-fill and clean 9.10 install:

    Re: 9.10 upgrade says I have failing hard drive

    I just upgraded my HP Laptop to 9.10 today and i'm getting the same Notification.
    it might be a bug, but its better to back up.

    Same problem here, with a Compaq Presario R3000. It's got a 60GB Hitachi Travelstar HD, showing:

    Normalized: 100
    Worst: 100
    Threshold: 5
    Value: 65551 (!)

    Everything's backed up just in case, but I'm going to ignore this warning.

    Re: 9.10 upgrade says I have failing hard drive

    Same problem on Dell XPS 1330 using Samsung HM250JI. Infact upgraded on two different mahcines which are way older without any errors. Strange that most of them who reported this problem are using Samgsung HD. Is this something to do with this brand of HD ??

    Same problems here. Palimpsest Disk Util says I have 445 bad sectors (it was 444 yesterday) on a 12 m/o 500GB Seagate Barracuda that gets little use. This is the third of three disks in my box.

    I have SMART software on my Windows partition and it says the disk is fine. I have never had read/write problems to/from the disk. With this conflicting information, which do I believe? My data is always backed up so I it appears to just be a waiting game now: either the disk fails soon, or it doesn't.

    Re: 9.10 upgrade says I have failing hard drive

    Ubuntu is reporting that my drive is failing, but I'm suspicious it's a program bug. The tool is reporting that my drive is 18.6 years old. So, either my drive is reporting false information, or the diagnostic program is buggy.

    Same here! hd samsung hm251jj on a dell studio.
    I did a bunch of diagnostics (they took a few hours) on hd and everything seems ok. I am ignoring the message (disc failing - disc has many bad sectors) at my own risk.
    I am not removing the warning, I hope it will disappear soon after an update .

    I ran your code in the terminal, and my raw value is in the billions... I have a Fujitsu ATA drive, and I can't find diagnostic tool for linux from the website of the manufacturer. Anyone advice on what to do now?
