    External Disk Corrupted or Unreadable


    Sounds pretty serious and I hope I have not missed this problem posted before.
    I have a Toshiba 2TB External HD that came with NTI Backup software. Seemed to work fine until Win 8.1 installed and now I get the 'Corrupted' message, although the Drive shows up in This PC. Driver appears okay and as far as I can see the USB 3 hub the Drive is connected to is working. Have tried in USB 2 but with same result. I have been advised not to Format the drive.
    Any ideas please?

    Try to run scandisk from a elevated cmd prompt.
    Try a different cable, USB 3.0 can be very fussy about cables

    No change.


    Many thanks for your suggestion. I have tried a different cable and, after searching how to do it, I tried CHKDSK for the drive but got a similar message, as before suggesting drive corrupt or unreadable.
    I have also just tried a brand new drive and getting same message so something a bit deeper I fear.
