Seagate Barracuda 1TB 7200.12 I/O error

I just bought a Seagate Barracuda 1TB hard drive to use as a secondary drive just for storage. Unfortunately when I'm copying files over to it after about 20 minutes i get "The request could not be performed because of an I/O device error." After that I can still go inside the drive with windows explorer but i can't go beyond 2 folders deep. I can only make the drive work again by restarting my computer and after that i can access all the data i was copying over to it.

The strange part for me is when I had copied over 100gb data over to it and it froze on me about 3 times before i gave up but when i copied all that data back to me it didn't freeze on me. After that I used a full format on it which took about 2 hours and it didn't freeze. Then i tried copying files to it again and it froze after a while. So my conclusion is the drive freezes only when i'm copying files to it i can copy files from it without it freezing. Basically I need to figure out what the problem is and if i can fix it or i need to return it back to the store.

I am running Windows 7 x64.

  1. Test the secondary hard drive with SeaTools for Windows, and the primary hard drive with SeaTools for DOS:
  2. Hello,
    I have tested it with
    Fix all fast
    SMART Check
    Short drive self test
    Drive information
    Short generic and they all pass. The other tests
    Fix all slow
    Long Generic take a very long time and i haven't finished it yet. I have a question the advanced tests say it could make the drive unusable for my system. Does this mean it carries a risk of permanently breaking the drive?
  3. souds like you are having issues because of the setting in BIOS...make sure you dissable AHCI function and see what happens, if you still get errors try updating your motherboard's drivers
  4. My motherboard is a very old Asus P5QL motherboard and both its firmware version and chipset drivers are the latest and I didn't have the Sata configured as AHCI. I have found out i can't disable write chaching on my secondary drive. I don't know if it helps or not. I'm still running SeaTools
  5. switch the cable out just in case

    hdtune pro can tell you about any 'pending sectors' -- if there are any, that will cause the issue, if so get warranty for the hdd

    otherwise, there are other issues (psu/sata ports/ram etc)
  6. I took it back to the store and got a replacement. This one works just fine now i'm certain it was a hardware issue
