Hello Jamie ,

The main reason for using this utility is when you suspect there may be a problem with a Windows XP system file.

Perhaps you get a dialog box appear informing you of a problem with a .dll file, or your program will just not load! It is therefore worth checking to see if there are any corrupt system files using scannow sfc.

There are heaps of other run commands here is a good website:

I Hope this answers your questions.

GtP is right - sfc /scannow checks the authenticity of the system files and replace the files that have been "fiddled" with.

chkdsk /r - checks the HDD and repairs errors, locates bad sectors, and recover readable information

The bad sectors will not be "repaired", but are marked so Windows avoid them in the future.

This is not a problem anymore Jen as in my post No.4 is states that its just a wondering.

I dont see the relivence of it being in the Hard Drive Support Forum as its no longer an issue.

Please tell me if i am incorrect.

Maybe it should be in the Microsoft support forum, but IMHO it's no big deal.

Jaymie - please learn how to take a joke. I wasn't trying to offend you.

The bad sectors are "dead" - you can't read from, or write to, them. I.e. they can't spread malware.

*edit* GtP - what spell checker are you using?
