whats the Chkdsk utility?

I have had this happen to me before, it was an ugly scene. I had a PS assigment that required about 30 hrs of work, and it corrupted on me. So I crammed 30 hours into 1 night. Needless to say, I didnt do so hot.

I never really found an answer to what caused it, but once I dedicated my scratch disks to a larger drive, it stopped all together. Although it happened to me again recently, and again, my preferences seemed to be reset.

If you dont have a back up then you might have a corrupted file written to your hd. You might want to run the defrag, then run scandisk to see if you have any bad sectors. in the future you also may want to designate a partition for scratch space (depends on what size of files you use and how much ram you have. If it's web work and you have over 512mb of ram, chances are you dont really use your scratch disk much.) Dont know if you did already. If you cant recover your file in anyway, dont keep it on your hd.

*edit.... one thing that I think people dont do, but if you get a crash, ie like if you experience a big red X pop up complaining about a fatal error or what ever. Shut down and wait a few seconds, then restart. Windows tends to lock that crash into memory, even though it thinks it is gone, and you have a piece of corrupt data sitting in your ram just waiting to get written to your hd. Shut down (dont hit reset) and let the ram clear out.
