Data Error (cyclic Redundancy Check)


  • I Have an Iomega HDD external Hard drive I've had a year now and it worked perfectly till about a week ago. Suddenly It started asking me to format it and when I click cancel it would give an error saying "Data Error (cyclic redundancy check)" I tried doing all i could find on the wed with chkdsk etc.

    it still doesn't work it's needless to say that I have extremely important files and pictures on this drive and the last thing I want is to format it and lose everything I have. 

    I have tried using recovery software in order to transfer all the data to another location but they can't access the drive due to the same error.

    I'm using Windows 7 if it helps in any way thank you.

    Please Help Me.

  • Use diagnostic tools from hdd vendor support page to check if hdd is OK.

    Check the teperature with CrystalDiskInfo or similar. Make sure that HDD works under limit temperature.

  • Hi,

    Please visit your external hard drive manufacturer’s website and look for data recovery tool or disk checker tool for your model to check your drive.

    It is also recommended to contact the manufacturer support for help.

    Hope this helps.
