I had one 120GB Spinpoint, which developed one single bad sector after maybe a year of use. The Samsung's disk checking utility is reporting it, but I've first noticed it first when one MP3 file wouldn't copy over when I tried to copy it. S.M.A.R.T. never reported any problems, btw. Disk is still working, but I'm going to get an exchange now, and I've switched to WD 160GB. I simply don't want to continue using disks that develop bad sectors even if it's so minor like in my case. I think you'll hear stories like mine for every manufacturer and every HDD ever made, it doesn't mean that Samsung's disks are bad, I still think they are quite good in fact.
