CRC error while copying

[ruhulamineee]

I am going to copy some documents one drive to another drive but it shows CRC error and data unreadable.

Am I going to lose all data?

what would be the solution?

CRC is cyclic redundancy check, which is a error detecting code. On you hard drive, there are a defined blocks of data. When the check fails, that means the checksum of the number of blocks of data does not equal the sum of data as computed from within the data algorithm.

Most of the cases you would possibly lose part of the data stored, you can use scandisk to mark that block bad so it will not be used again.
