It probably is possible to read Windows' 'Dynamic Disks
', but I don't know that it'll be easy!
Basically, the old-school way of doing things (which works perfectly well) is to have the potential for 4 primary partitions, or 3 primary partitions, and the 4th an extended partition that holds logical ones. So, for example, my harddisk looks like:
hda1 = primary partition
hda4 = extended partition
hda5>14 = logical partitions held within hda4.
WDD completely screws with this idea, and even Windows sometimes can't read the things! There have been many, many, many reports of people wanting to dual-boot Win2k with WinXP, only to find that WinXP has changed the harddisk into Dynamic Disks, and completely screwed Win2k. Not happy people.
