About 2 years ago I bought a G-tech drive, going for quality.
After a year and a half, it started clicking heavily.
I sent it to G-tech, and after six weeks I got the replacement.
Now, two weeks after I got it back, it starts again tick-tack, tick-tack, when transferring a DVD to it.
Then it goes silent, and you have to go close to the drive to hear some sound.
Then you can hear the tic-tac again. It's a very low noise.
