Data cyclic redundancy

i have bought my passport lasy year. due to some files that i have deleted from my hard disk, my hard disk is recognised but unaccessible , asking me to format it, and i choose to cancel it, it shows the error due to data cyclic redundancy. what can i do so that i won’t lose all the important data inside the hard disk?

If you search online you might find certain tools to fix this type of issues.

We do not recommend any specific software and always suggest to keep backup in order to avoid issues like this.

This is most unhelpful

Kindly provide me link to fix data cyclic redundancy error.

Or otherwise help me to replace my WD hard disk as it is under warranty.
