"DISK STRUCTURE IS CORRUPTED OR UNREADABLE"?

You'll get this error message rarely when you're working on Windows Platform.

Let us see how to solve it.

Go to Start->Accessories->Command Prompt->Right click and Run as administrator.

type 'chkdsk /r'

You'll get a warning and you will be asked to Y/N that the check will be done on next startup. Say Yes.

Restart your PC.

Disk checking will be done on the startup.

Problem solved.

Thanks.
