HDD dying? Bad sectors? Can access files, but can't transfer or store files.

I got an HDD never gotten any issues but suddenly when I try to transfer some video files to another storage drive, it just froze up after several minutes with extremely slow transfer speed of 200kb/s and gave a message saying I/O error, drive not found. But I am able to access and open files just fine :S

RE: I decided to switch the sata port with my DVD drive and my transfer speed got back up to regular normal MB/s rates. I have no clue what happened and I want to ask could this be the beginning of a drive that is failing? Or a failing motherboard sata ports?

If its the latter issue, then it presents even a bigger future problem, since it shows excessive wear and tear on the motherboard that components are starting to give up.

  1. Well, it could either by a temporary Windows glitch, or signs of a dying drive.

    To test for the former, i'd disconnect & reconnect, and also restart the system. Swap the port of connection, cable, etc. If you have the option to, perhaps test on a different system.

    As for the latter, I'd recommend using a HDD test utility to check the drive. The software would be able to post details based on the S.M.A.R.T. monitoring. There are several free utilities for this:

    As for data safety, assuming its just a backup, then I guess its no biggie. Else get another drive and copy all your data just to be safe.

    It may well just be a windows glitch, since its windows OS. But i'm just concerned about if its actually the sata ports showing signs of defect, as it may be a near future indication of a mobo that is starting to fail on components.I had prior experience that if one thing on the mobo goes, other things will go with it very soon.

    Hi there meat_loaf,

    It would be nice if you just back up the important data stored on the drive until you sort this out. It is always a good idea to back up the data you can't afford to lose anyway.

    I/O(input/output) errors could be caused by the connections. This means that it could be caused by faulty cables and ports. After everything works just fine after you attach the drive to another port, then there is most probably something wrong with the SATA port, as you guessed.

    I would agree with virtualdanger and say that it will not hurt to test the drive with a tool that can provide a SMART report. Look for pending/reallocated/uncorrectable sectors.
