All of the sudden the raid controller was reporting an error on one of my raid 0 drives. I also keep experiencing random program hangups in windows. I took the drive out of raid and ran it through seatools on another machine. Seatools reported that the drive had bad sectors. I ran the built in repair tool, and ran the tests again. It passed every time. So do I trust the drive to put it back into raid, or will more bad sectors show up later?

Honestly you never know...
There's programs out there that will actually fix them. Then there's Chkdsk, it just flags them as bad, and tries to work around them.
 
Honestly anytime I ever get a bad sector, it is trashed. I don't risk it.

Agreed with EliteGeek91. Just RMA the drive back to the manufacturer and get the replacement provided it is under warranty. Best not to chance additional issues.

Also IF/when you can get everything copied to another drive, do so asap.
 
I recently fixed a ladies laptop with this issue. Once I could copy and paste her HDD contents onto mine, and I did. Guess what? Hers crashed for good 20 mins later, I was SO glad I did that, to save all her important info.
 
So please do that if possible asap.
 
Also contact me if you need a good sector repair tool. I have a friend that works with HDD's, and I know he uses a great program. But I forgot what it's called. I can ask him for you though.

I was able to do a backup before I deleted the raid. It was weird though, windows would not let me create a system image. The drive is an oem drive from an older dell computer, so no warranty unfortunately. I will just install windows on a single drive, and leave that one out. I wait till hd prices come back to normal and pick up a new drive. I'm done with raid, I recently got an ocz synapse drive and everything is so much faster. Thanks for the advice Elite.

hard drives dont go bad sector by sector....
 
you may want to make an imagige of the drive everyday and restore incase all efforts fail
 
 
run the chkdsk /f and let it run for the entire period of time it shoudl automaticly block those sectors
