Re: EWF disk overlay on a different hard disk.

Thank you for your answer.
Is that possible to upgrade the CF card without changing anything on
the disk?
One of the reason why we use the CF card plus hard disk is to upgrade
the system easily just replacing the CF card.

My concern is that the overlay partition exists on the disk and there
may be a mismatch between the upgraded software on the CF card and
overlay on the disk.

Best regards,

Jeong

and enough free space (8MB) for EWF to create the EWF Volume during FBA.
During FBA, EWFDLL.DLL will hunt for free space to create the EWF Volume.
Windows XP Embedded Advanced - Chapter 19 - 19.3.4 and 19.3.5 describe this
scenario.

Hi,

We have designed a hardware appliance which has a CF card and hard disk
drive.
The CF will store the operating systems and the hdd will be used to log
history.

We want to make the one of the hard disk partition as the overlay for
the CF. Is this possible? If so, how can we choose the overlay
partition on the disk?

Thank you.

Jeong
