    checking the status of the HDD

    Recently my HDD starting making loud noises. I blow the internals out quite often to clean it from dust, and the noise is surely coming from the HDD. Its not clicking noises, but sounds like writing/reading, but just more loud than normal. Loud enough where if people are in the room, they ask what that noise is.

    The HDD is the internal default that came with the computer. It's about 2 years old. The Desktop however is always on. I have it hooked up to my TV via HDMI, but i use the TV data from my 3TB external HDD, not the internal for reading data constantly.

    I have had an external Seagate before and it died quite early, so i am not fond of Seagates anymore. My external is Western Digital, and i have never had a problem with those. It's weird that Seagate are more expensive but seem to last far less than WD. So i am trying to find out whether i need to cough up the money to buy a new HDD. I am not too concerned about saving data, as i would just re-install Ubuntu on a new HDD if this one fails and i didn't have a backup. Plus most important data is saved at numerous places. So it could die tonight and i would be like whatever, for the exception of me having to buy a new one. But i was trying to avoid having to buy a new one if i didnt have to.

    I am not sure what smartctl is or does, or if its the best method, but i came across:
    I am not sure what these results even mean?

    Re: checking the status of the HDD

    I've had a lot of Seagate drives and have had very little trouble with them ... but I guess that's just the luck of the draw.

    Another - friendlier - way of getting info about a disk status is to use "Disk Utility" which you should be able to find on your system, it has a GUI.

    As for what all the numbers mean - well, some of them are worryingly high but, then again, some of them are stupidly (implausibly) high and I'm never entirely confident about trusting the numbers I see in these reports. For example, your disk appears to have been running for longer than the known age of the universe ...

    At the end of the day, if the disk is making graunching noises then it is about to die, no question. I'd trust my ear if I were you!
