    Bad sectors on HDD, should I expect it to brake in near future?

    Hi.
    I keep getting these errors every ~30min. Should I be worried about them or expect that it will brake soon. The disk doesn't contain any important data.
    Code:
    19:11Device: /dev/sdb [SAT], 1 Offline uncorrectable sectorssmartd
    19:11Device: /dev/sdb [SAT], 2 Currently unreadable (pending) sectorssmartd
    18:41Device: /dev/sdb [SAT], 1 Offline uncorrectable sectorssmartd
    18:41Device: /dev/sdb [SAT], 2 Currently unreadable (pending) sectorssmartd
    Disks says "Disk is OK, 2 bad sectors (35 C / 95 F)"
    I get one huge but short drop in read speed when benchmarking with Disks.

    I am presuming that the disk is one installed a laptop, as it is rare to have a bad sector occurring on a desktop drive. Usually caused by shock while disk was operating.

    Irrespective of disktype or cause, you need to run the utility to flag the bad sector(s) as unavailable and to relocate any data that was stored therein.

    If you start to see many other messages about bad sectors, then you can presume that the drive is failing

    Should I be more worried since it is a desktop drive.

    How old is the drive? 4 years then yes. You can get a new drive for around $40+ (1 terrabyte) from one of the internet vendors.

    Closer to 10 years I believe. Well I guess I will change it if I get any more errors.

    If you go the replacement route, see if your computer has SATA support. (It might not). If computer does not support sata, it may be time to buy a new / used computer.

    or a SATA to PATA adaptor, besides which the errors indicate it is a SATA drive.

    You should expect any drive to fail at any time, always make regular backups.

    I would backup up all data off of the drive as soon as possible. Then replace as soon as possible. Drives are cheap, so a suspected drive should be replaced immediately. Since most drives are rated for 2-5 years, you got good life out of the current one.

    Many would say your drive has already failed. This is the equivalent of the "check engine" light on your car.
    Best to take action now rather than wait for total failure.

    Tower: GigaByte (970A) / AMD FX 8320 3.5Ghz x8/ 16GB/ 9TB Sata III/ AMD 6770HD/ fc29.x86_64
    Bookshelf: Shuttle DS61 (H61)/ i3-3225 3.3Ghz x2/ 16GB/ 320GB Sata II/ Intel HD 4000/ fc27.x86_64

    Thanks for answers, I tried to do some googling and I believe that it's safe for me to keep using it, if there doesn't show up any more bad sectors.
    That drive is in very low use, mainly for dumping some not important semi temporary files. (My "main drive" 256GB SSD can sometimes get bit small)

    safe is a relative term but it's your choice to risk an already failing drive. SATA form factor SSD around 500GB are now much more reasonably priced and the current generation 3D NAND ones carry much higher total read/write values and 5 year warranties from Samsung and Crucial for example.
