I installed ewf on the ssd with nlited licensed xp pro sp2 . I issued the command "ewfmgr c: -enable" but I get error "Failed getting protected volume configuration with error 1"
I also have a sdhc configured as fixed drive D: and when I do "ewfmgr d:" I get "Failed getting protected volume configuration with error 50"

Incidentally I have dell inspiron dual booting vista and xp. I have ewf support on xp and there was npt problem there.
That was BTW a full xp rpo installation and ntfs partitions.
