[QUOTE="bobtomay, post: 598301, member: 24160"] Looking at the report from Smart Utility, it could very well be correct. Seems to be giving you a complete picture of the drive. And if you're not accustomed to reading such information, it can be alarming. Was use to using utilities like this on my Win systems. I can tell you that 20 bad sectors is nothing to worry about. Have had plenty of brand new drives with more bad sectors than that. One of the old 40GB back up drives on my XP machines was showing something like 500 bad sectors the last time it was checked (2-3 yrs ago) and is still running fine. These sectors get marked so they're not being written to. That being said, I would be somewhat concerned due to it being dropped. Mentioned you're doing daily back ups. That's a good thing. Personally, I don't recommend replacing a drive until it fails, or exhibits the typical symptoms; e.g. it starts a new clicking sound, problems booting, or over 15-20% bad sectors. If you're in a position where you can't afford for your system to go down for a few hours due to drive failure, (imho) a much better response is to have a bootable backup in place. This allows you to continue your work until you have the time to replace a failed drive. [/QUOTE]
