Yesterday I was installing a hard drive (ST31500541AS - no speed is not important here) in a customers computer. I did a quick format and booted up the system and all was well. Delivered the computer to the customer, when it was booting up I could hear a terrible clicking sound. The system would click loudly and lag terribly. I assumed I had ruined the drive somehow. So I took back the computer, ran a full scan with SeaTools. 4+ hours later, it came back with no errors. So I did a full format, test drove the computer again and the clicking was gone.
It seems that all is well, but I'm a bit worried that this problem might popup again.
Is the problem just that I was lazy and did a quick format at the beginning when I should have done a full format, or is the drive a time bomb that I should return?
Thanks for looking,
