data error cyclic redundancy check

Hi,

Cyclic redundancy check errors normally occur with damaged or faulty discs. This could have occurred during the burning process, in transit or could have just been duds fresh from the factory.

Method 1:

Try to use the external hard drive in a different computer and check whether you are able to access the data that is present on the external hard drive or you can try to connect it to a different port and check.

Method 2:

It might be that some data that is present on the external hard drive is corrupted. I would suggest you to check the drive for errors. Follow the steps mentioned in the article given below.

Once you have checked the drive then try to access files and if you are able to access then backup the files and then format the hard drive.

Method 3:
