I've got a laptop with a hard disk that I think is going bad and would like advise for options/tools which can help me do diagnostics and maybe repair or help me to salvage files.

Could you elaborate one what symptoms the hard disk is showing?

The best way to save the data would be simply to clone it with some kind of imaging software and then apply that image to a new hard drive. As far as repairing any potential logical failures on the disc, you could search for a boot CD that has hard disk repair tools on it. Before you attempt any repairs, backup the files first. In fact, once a disk shows signs of failure, treat it like the plague. Transfer all files from it and toss it in the dumpster.

I can't boot to the OS in anyway. So I've been trying to find a boot disk of some kind that would allow me to in some way to transfer the data off or patch bad sectors.

You could simply use a Knoppix CD or maybe try this tool out. I've used Knoppix for things like that before but not the second link. There are also forensic Linux based live CDs out there, but you'll need some familiarity with Linux to work with them.

If you can copy the files off of the hard drive, and you still want to attempt a repair, you could try some of the tools on the Ultimate Boot CD.

What if I can't access the drive? Is there a way I could try and patch bad sectors and see if I can make the drive readable?

If you can't even see the drive there's a lot more than bad sectors going on. That could mean bad power, fried HD logic board or hopefully something as simple as a bad cable. Can you extract the hard drive and plug it into a different computer or some kind of SATA to USB adapter? Really, if you cna't even see the drive then it's probably time to contact some kind of data recovery service... however those can be quite pricey. Sad

if i shut the system down for like 30 mins, i can access the drive when i boot it up. however, after awhile the system will just lock up and the drive will go into this humming/spin phase and then you pretty much have to shut the system down.

so this obviously would mean a bad drive due to bad sectors? is there anyway to attempt to patch/block the bad sectors?

Go into your BIOS and identify the manufacturer of your drive. Then get access to that manufacturer's Drive Utility CD either by downloading it or ordering it.

LOW LEVEL format the drive after booting from the CD.

This mightfix the problem. If not, then I'd suggest taking the laptop into a shop.

Actually, that suggests even more strongly that it is a mechanical / physical failure of some kind with the drive. Bad sectors would not cause that kind of behavior. It would cause file system corruption.

Just so you know, if you follow Tom Bair's advice, that would completely destroy all data on the drive. If you want to recover the information you may want to put the hard drive in a plastic, air-tight bag and place it in the refrigerator for a few hours and then plug it back into the computer. From there, boot into a recovered CD of some kind and begin transferring all the files off of it that you can. That drive is a goner and will completely fail in the very near future.

Shame on me for forgetting to mention about all data being erased. I should know better than to leave something like that out.

Actually, Nonapeptide's solution above is the best advice to date, IMO.
