no paging file when booting XPe from USB CF reader

I have a 4 GB compact flash with XPe which successfully boots when the CF is
on the motherboard. A small paging file requested in the XPe build is
successfully created.

When I put the same CF into a USB reader/writer and boot from that, the boot
works OK but I get a system message at boot time indicating that there is no
paging file. I checked the paging file size in the System parameters and it
shows zero instead of the normal size requested.

Any ideas why the paging file is not created when I boot from the USB
reader/writer?

Thanks,

No guarantee that this is the correct answer, but the first thing that
occurs to me is that USB disks will always be seen as "removable" by the
OS, and pagefiles can't reside on removable drives.


My question is, do you need, or even WANT it?

Today's CF's will stand more write cycles than some years ago, but I still
think it's a bad idea to boot from CF without using EWF, and I think EWF
and a pagefile on the same volume don't blend well ;)
 
Yes, I think you're right - you can't have a paging file on a removable. I do
have EWF and a paging file at the same time and haven't had any problems yet.
We are using the paging file to get some extra performance. Are you thinking
that the paging file will substantially reduce the wear life of the CF?
