Chkdsk finding unfixable errors?

Whenever I run chkdsk in read only mode I get the following message thatis pasted below. First, I have ran the error-checking program in theTools tab when right-clicking drive C and select Properties. I havechecked both boxes that say "Automatically fix file system errors" and"Scan for and attempt recovery of bad sectors" It says it must reboot toscan which I do. It scans in 5 different stages and then reboots againand acts normally. I don't get any disk errors anywhere else and have noidea if I should try to fix the errors or not worry about them. Maybe afalse positive? Also it mentions towards the bottom that there is a 65MB log file that I cannot find. How do I access this log file? I haveWindows XP Home SP 2. The hard drive in question is a SATA from WesternDigital. It's model number is WDC WD800JD-75JNA0.
