Below are the two original error messages the client threw when the WHS backup failed. I ran chkdsk c: /r twice but still got the errors and no WHS backup.
I tried System File Checker (sfc /scannow), but the system constantly asked me to insert a system CD I simply to not have. I checked and re-checked all my registry entries to ensure SFC was looking to my HDD for the i386 directory, but I ran SFC over and over and it still kept asking for my system disk. Finally, I found out why from HP help files:
System File Checker scans and restore system files.

So it appears SFC works perfectly fine to confirm the status and replace system files where necessary *despite* the repeated SFC request for me to Insert your Windows XP Professional CD2 Now. Not one of the scores of tech help websites I visited offered this important piece of advice! I must have run sfc /scannow at least ten time before I came across this piece of information.
Once I realized sfc /scannow worked fine, I ran chkdsk c: /r two more times as the most obvious solution. Sure enough, it corrected more errors. I now have a happy green WHS tray icon and a completely backed up client.
