Hi, this may also sort your problem:

"The hard disk's file system is corrupted and will be restored"??

Here's what to do - as instructed by Sony UK (Tel: 0844 736 0595):

If you've tried `restoring` and it continues to reset/repeat to the same message:
Turn the console off by holding/pressing the power button down until you hear three spaced out beeps (before powering down);
Then hold in the power button again until you eventually hear a first and second beep - followed by a quick double beep, then take your finger off the button;
This should bring up a six option menu, such as `System Restore` etc;
Select `System Restore` and follow the instructions;
If in the event it repeats your first problem, i.e. repeating the same message, then repeat the above process to get back to the six options, although this time select `System Reset` or similar;
This will sort your problem although you will probably lose saved game data (if not backed up on a memory stick or something prior to your problem).
If you play Modern Warfare 2 online, then your data will be saved on the Sony Server anyhow and won't be lost.

When carrying out the above actions, the loading bar can be a bit slow at times. This is due to repairing the corrupted data etc on your hard-drive.

This worked 100% for me and I've no doubts will also help you.

Any problems please ensure you contact Sony on the number above.

Good Luck!!
