Personal PC on the Fritz? Unknown Errors.

[TekkieFreak]

Please help!

The other day, during a scheduled virus scan, my system showed a very odd (to me) error message.

The file or directory \System Volume Information\_restore{7EE62D59-3EA5-41E3-91E9-1406CAAD35AA}\RP242\change.log is corrupt and unreadable. Please run chkdsk.

Is this a registry key, or a file?

This is when accessing my secondary (D: 15 gig Maxtor) hard drive.

When I run chkdsk, I get no problems. However, if I tack on a /f, then it stops half way through with "An unspecified error has occurred." This is regardless of weather or not I run it in XP or schedule it to run before bootup.

If I delete some files from the hard drive, and reboot, they reappear. (These are files that are legit. I downloaded them on purpose (not virii). Utilities, and mpg trailers, mostly.

Another wierd one. I run Sygate Personal Firewall. I downloaded the latest version, but when I tried to run the executable install (from the same drive) I got "Only part of a ReadProcessMemory or WriteProcessMemory request was completed."

I have downloaded and run a detailed scan with the Maxtor diagnostic floppy.
It turned up nothing. Everything came back looking good.

Is there something pooched with the drive, or is something amis in my registry.
(that would be bad. I know very little about the registry.)

Any help is appreciated. Thanks.
