Hallo everyone!
I have created a bootable system using the target designer
(includes correct hardware and software). Next I used
diskpart to make a partition (500MB) on flash drive (1GB).
Previously an embedded system was operating on this disk.
After transferring the boot and embedded files and
rebooting the system by itself, the booting process stops
with: 'Verifying DMI pool data ......'. Nothing further
happens. I suspect that there is an ewf partition left on
the disk. However, how can I be sure? I have tried to
delete it with etprep, but this returns the following
error: 'Deleted EWF partitions = 0; Failed to swap El
Torito Disk Drive letter; Error 0x2'. Which tools can I
use to see and to remove this partition if it is indeed
there?
Thanks in advance!

Helmuth,

Microsoft does not recommend using diskpart tool on a Compact Flash because of the way Windows XP reports disk geometry on compact
flash devices, repartitioning your compact flash device may render it inoperable. They recommend contacting your compact flash
manufacturer for assistance repartitioning the device.

Anyway.. you may try to
1. Remove all the partitions on the flash (fdisk)
2. Reset MBR (fdisk /mbr)

Also, if you have a Compact-to-IDE adapter you may use XP Disk Manager to repartition or etc. your flash.
Also, there are better third party solutions out there (e.g., famous Partition Magic, Paragon Partition Manager, etc.). You may use
them to do low level tweaks on your compact flash with IDE adapter.
 
You should be able to see the EWF partition with diskpart. To delete it use:
delete partition override

Thank you very much for your answer. I was not aware of
the fact that I will need a different partitioning tool.

Thank you very much. I managed to find it with diskpart
and also managed to delete it.
