It could be a problem so I would suggest that you back up any important data as soon as possible. I just a SATA drive start making a clunk-whir noise when playing games so I have RMA's it.

It passed all the hard drive tests I could through at it, but it still froze up occasionly when playing a game. Removed it and now the system doesn't freeze in the same games.

Best not to take chances with you data
