Hardware and performance

This might be a stupid question but do you know if any attempt has been made to access the disk/disks by putting it/them into another machine using the same operating system?

Wow, Melanie - that doesn't sound good.

To be honest, it's a little difficult for us to comment without knowing what "Moodle has crashed" actually means. Aside from hard disk failure (in the case of a single disk setup) and assuming that no backups exist, there are few things that can make a Moodle installation's data unrecoverable.
Do you know about the nature of the crash?

Hope there's some way we can help out.

Try to get them to be more specific. As mentioned, if the hard drive is not broken, but some other parts of the server, then it might just be a matter of moving the drive to a working computer.

If the hard drive is broken, some data could still be saved. You could ask if it was possible to have the broken drive to be sent to a company/lab that could salvage some/all of the data. It can be a bit costly, but you could ask. For example: http://www.harddriverecovery.org/ (They have a free recovery consultation service).
