Hi! I bumped my HDD (ST31500341AS) and now it's making exactly the same noise:

Is there any easy way to fix this or my data is gone on this disk?

Can't be so easy : professional recovery - maybe need only a phone call. But you have to pay (as it is a 1,5TB multi-platter and multi-head it could be expensive)

Note : some crashes are unrecoverable and cannot get data on badly damaged areas on the drive (there's a limit).

If you mean "is there an easy way withoust spending money that I can do at home to get data back", the answer is NO.
