I heard there is a way changing the Hex data by WinHex, and then you could back to basic disk. But depends on what volumes you have, you may need to adjust it before you convert the disk. like spanned, raid0, raid5 volumes. These volume could not be convert through this way. If you do not want data loss, you have to pay for some money changing the dynamic disk back to basic disk. here is a "dynamic disk converter" from Aomei Tech who possess Partition Assistant. It is just a converter, so it is much cheaper.
They may of actually not known what you had been talking about. Some users did not think DYNAMIC right away. That post also with notify that users of other posts so maybe for future reference, they would know what users are asking. Cut them a little slack please(they had help countless users with problems here).
Back on topic.
Did you get your self all fixed up? What did you end up using/doing?
