Error <5737>, Error <16507> and cyclic redundancy check

Hello.

At my work we are have some trouble with our EMC Avamar Backup.

The backup is succesful, however there is some errors...

Below is the log files, errors:

2014-05-11 23:06:58 avtar Error <5737>: I/O error: Unable to BackupRead(3) "C:\Windows\assembly\NativeImages_v4.0.30319_32\System.Windows.Forms\635558b506364815e8348217e86fdf99\System.Windows.Forms.ni.dll" (code 23: Data error (cyclic redundancy check)).

We have tried to run a scandisk because of the code 23: Data error (cyclic redundancy check), but no error is found.

I have also tried to look at a error code book, for the errors 5737 and 16507, but I cann't get anything out of that and it doesn't tell much.

Anyone had similar error and maybe a solution?

Best regard
