A Cyclic Redundancy Check (CRC) is an error checking technique used by computers, specifically the hard drives or optical disks (i.e DVD/CD). A Cyclic Redundancy Check error is caused when data on the hard-drive or DVD becomes corrupt.

1) goto Run -> CMD

2) chkdsk [driveletter] /f /r   => [chkdsk f: /f /r

3) from the same drive (i.e f: drive)  type command  “diskpart”

4) which will goto DISKPART console and type command “rescan”

most the issue goes away.
