    Getting an error “ Data error (cyclic redundancy check)” while trying to access the contents of an External Hard Disk

    I use an external Hard disk of capacity 1 TB but yesterday when I inserted it, an error message flashed “You need to format the disk in drive E: before you can use it”. Since it contains many important folders, I decided not to format it so I cancelled it but again on double clicking the hard disk drive, a different error message flashed “Drive E:\not accessible” and “Data error (cyclic redundancy check)”. What does this error mean and How one can solve this issue.

    try to use an anti malware or the hdd support files have been deleted this may b the main reason so recovering the hdd files is the only option test .... it may also cause due to virus .. use some anti malware first

    1. Check the cause. In the case the CRC error was thrown by the hard drive, the cause is likely data being incorrectly written to the hard drive. This can be caused by either the operating system being corrupt, or a power loss.

    2. To fix a hard disk CRC error, run the CHKDSK application. In the "My Computer" folder, right click the affected hard drive and click properties.

    3. (In most of the cases this doesn't work because from GUI It won't show all the properties of the disk; It will end-up without doing any disk check. The alternative to this step is execute commands from command prompt as below:

    1. Run CMD as an Administrator

    2. type chkdsk G: /f /r

    3. Run DiskPart utility from the same command prompt type DiskPart

    4. Once utility is loaded run "rescan" command. This command locates new disks that might have been added to the computer
    5.Hopefully problem would be resolved and you would be able to explore your disk

    4. You can trace the logs of chkdsk utility from Right click on
    5. My Computer' -> Manage -> Event Management -> Application logs.
    6. Enter the "Tools" tab and click the "Check Now" button. A small windows will appear, make sure the "Automatically check for filesystem errors" box and the "Find and repair bad sectors" box is checked. Then click start.
    7. Note when it can't be fixed. In the case that an optical disk (i.e., a DVD/BD/CD disk) is reporting a CRC error, there is no way to fix this. If you burned data to the disk yourself, try burning said data to another disk, this time at a lower speed. 4x is the recommended speed, especially when burning operating systems (i.e an Ubuntu LiveCD) to a disk. The higher the speed at which the data is burned, the higher the chances errors may be written to the disk.

    Re: Getting an error “ Data error (cyclic redundancy check)” while trying to access the contents of an External Hard Disk

    Dear friend,

    This problem is caused due to bad sectors on your hard drive.
    You can use hard disk utilities such as HD Tune, Acronis Disk Director Suite, CheckDisk etc. for checking the bad sectors.
    These utilities also prevent the data to be written on bad sectors.

    OR
    You can format the drive.
    To recover the lost data you can use any data recovery software such as EASEUS Data Recovery Wizard Professional and similar.
    Today it is possible to recover the data fully .
    You will need another drive which has size equal to the size of data to be recovered.

    Thanks!
