Query: Made grinding/clicking noises after two weeks of usage.

I just purchased this item a few weeks ago after reading that the firmware was updated & the model number changed, but I still found problems.After using it for about two weeks without any problems, I suddenly began hearing clicking noises and grinding when the drive was running and reading/writing data. I didnt experience any data loss, or errors, but the noises led me to believe that data loss/errors would begin occuring soon after.I returned it and purchased the Maxtor OneTouch II which received great reviews.
