When i try to restore a DB from a database backup file i get the following error after 10% of the data has been restored

System.Data.SqlClient.SqlError: RESTORE detected an error on page (0:0) in database "dbName" as read from the backup set.(Microsoft.Sqlserver.Smo,

Does anybody have a fix for this or know what it means? Please help.

Verify the database to see if it is corrupted.

RESTORE verifyonly FROM DISK='C:\Backup\Mydatabasefullbackup.bak';

You may also want to ensure that the original database you backed up from is not corrupted.

DBCC CHECKDB ('XXX') WITH NO_INFOMSGS, ALL_ERRORMSGS;

on the original machine.

Here's some info on corrupt databases:
