Hi Herb,
there are some reason why you should consider to upgrade to a newer winpe:
- One thing is indeed drivers (There is already hardware where no xp drivers exist)
- it's preferable to use the same (or newer) PE-OS like the Windows version on the PC
(offline systemrestore-, SFC-check-, bitlocker-, VHD support, ...)
- As you mentioned Checkdisc will properly cause more trouble as it could solve
- also a comparable Win7 PE, will boot and operate fast then a BartPE
