Hello Everyone,
I said I would be back to this thread and here I am. After having this problem more than once, I am firmly convinced that the main cause of this error is hard drive defects (bad clusters)(with the exception of the error occuring over a network). If the hard drive is RELATIVELY new, I would run Norton disk doctor on win 95, 98, & me and make sure automatically correct errors is checked and scan the entire surface of the drive. The bigger the drive, the longer it is going to take. For Windows 2000 & xp, go into a dos window and type: [chkdsk c: /r] without the brackets. Type Y when it asks if you want it to run on reboot. You may have to run this up to three times. Also, this takes a long time because the /r makes chkdsk do a complete surface scan. If this does not work, or the drive is older than 3 years old or it is making any noise that you didn't hear before REPLACE THE HARD DRIVE IMMEDIATELY!!!!!!!!!!!!!!! Out of two computers, one was ok after running chkdsk /r three times (the error went away and hasn't been back since) the other one had many many errors (physical) and I had just enough time to copy the data and replace.
