Interesting. I had the same problem with sfc /scannow. I have a DELL
C521 with XP MCE, so I don't have MS CD's - just one CD from Dell.
When asked to insert the XP CD I put in the one from Dell and sfc
continued to run. After some minutes the program asked for XP CD #2 -
a thing I don't have.
Since my machine is under warranty, I called Dell. The techobabe that
took my call started guiding me thru various steps that I recognized
was going to reinstall all the software and reset my machine to the
condition it was in when delivered. I told her I did not want to do
that, I just wanted to run sfc. She told me that a complete
reinstallation was my only option.
There is no problem with my PC that I am aware of. Everything seems
to work okay except that I can not check my files with sfc.
I might try the registry change and set that pointer to c:\ instead of
the CD reader as described in the referenced article.
Anybody have thoughts on whether this is a good idea or not. I would
set a restore point first of course.
