One of my hard drives, a 3-year-old Maxtor 160gb SATA, is reporting through SMART a health rating of 73%. Is this bad yet or will it last longer? What percentage is considered dangerous?
 
personally I'd say anything less than 100% is not worthy of storing important information.
IMHO - Backup your files regularly or get a new drive.
 
I wouldn't worry too much about it, but you should always backup your data no matter what. What are you using to get the SMART status? I'm using a program called HD Inspector and it shows different percentages for Reliability, Performance and Error resistance. The power on time counts against the overall reliability of the drive as well as each spinup. Seeing as your drive is 3 years old and if you turn it on and off a lot that could count against it's reliability status, but doesn't mean the drive is going to fail.

I'm not sure I really trust the SMART reporting. I have a computer that has been running 24/7 for the past 3 years and SMART shows the drive at 82% reliability & performance, and 100% error error resistant. I can believe that considering the amount of power on time the drive has.

On two other computers SMART reported 100% on their drives for all values. I installed 2nd hard drives in those two computers and now SMART reports very low reliability, performance and error resistant numbers for the 2nd drives, which are brand new.

I'm no expert on how SMART works, but maybe the drive has to prove it's reliability over time to SMART because on both of those computers the numbers continue to increase (more reliable) as the days go by. On one system, the 2nd drive was at 34% on all values right out of the box, but is now up to 37% a week later. The other showed 54% on all values, but is now up to 56%.
 
What is a good drive diagnostic tool then? Recommendations? Preferably free, I have always used BelArc Advisor but I know that it uses SMART
 
Download the Ultimate Boot CD, plenty of disk diagnostic software on it.
 
From all the data ive gleaned, and if you can get your hands on the publicly released report was a study done by google on hard drive reliability and failure rates, some drives were reporting SMART errors and recommended replacement, and would still operate flawlessly and pass other diagnostic tests, and some drives never reported SMART errors, and failed. SMART is still a (*ahem* pardon my French) crap shoot.
