Trying to back up my database for one of my xenForo forums, and no matter what I do I get these errors.
I've tried doing innodb force restores with 1, 2, 3 with similar errors (I might have been doing them wrong).
In any case, I feel like this seems to be the more appropriate forum to post it in.

Here is one instance of the errors that I get:

Code: 
InnoDB: Error: tried to read 16384 bytes at offset 0 819200.
InnoDB: Was only able to read 0.
141102 14:35:53 InnoDB: Operating system error number 5 in a file operation.
InnoDB: Error number 5 means 'Input/output error'.
InnoDB: Some operating system error numbers are described at
InnoDB: http://dev.mysql.com/doc/refman/5.5/en/operating-system-error-codes.html
InnoDB: File operation call: 'read'.
InnoDB: Cannot continue operation.
