That's interesting. Basically, if I'm reading you right, all you're doing
at this point is setting up a basic RAM overlay, and then going and making
the required modifications manually. That is, as I understand it, the old
process, and it requires that there be a blank, unpartitioned area on the
target hard drive where EWF can set up a partition.
The purpose of the MSDN article is to circumvent the need for a separate EWF
partition, and to have EWF configured for RAM Reg operation when it finishes
FBA. This should simplify the process.
I did identify a typo in our instructions that may have been causing some
problems, however - please see my new thread titled "Resolution for EWF RAM
REG 'Incorrect Function' issue" for more information.
In Step 8 of the instuctions, a reg key is called out that has a period at
the end:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\{71A27CDD-812A-11D0-BEC7-08002BE2092F}.
This key should not have a period at the end - this will cause the data
underneath it to be stored at the wrong location, and thus the system will
never pick up the EWF component. Simply remove the period when entering
this information into Target Designer, and this should resolve the problem.
We're taking steps to correct this error as well, and we apologize for the
confusion.
