Hello,
For my understanding: You made disks dynamic and THEN, AFTERWARDS you created volumes, correct?
6 Pulled drives - they show as dynamic but unreadable on XP, W2K and W2003
.. while you should be able to import them normally ... it maybe wothwhile to talk to MS support ... and What's the size of the disks + are the OSes you try capable of dealing with those sizes. I am asking because it's not the first time Windows can't access the LDM at the end of a larger than 128 Gb disk ... all OSes need the latest SP + in case of W2k you need to edit registry, not sure about W2K3.
Anyway, if DiskPatch does not pick up that 2nd volume then it can not recover it either - it is strange though; normally that second volume will start right behind the first and DiskPatch should be able to detect it (during the quick scan). Alternatively, if it comes to pulling the data off being the only solution, see if iRecover can still handle the LDM. If so, recovering the data from the disk should be pretty straight forward.
