7Gb of PC hard drive??! Really, once you start using PCTask, you'll find 7Mb adequate for the amount it'll get used, unless you have loads of really really old and really really slow stuff you want to run!!!
In any case... PCTask at least will support two drives (harddrive files) and each of these can be partitioned.
I've just fired up PCTask with DOS 3.3 ( :-) yes, it's the only one I have on 720Kb disks) and was able to create a primary partition, then an extended partition, then a logical drive within the extended partition, giving me C: and D: drives on the same PCTask harddrive file.
Similarly, I then created a second PCTask harddrive file and was able to create another primary partition on that, then an extended partition with two logical drives.
So it all works, but you're really just better off creating a single harddrive file and a single partition on it, especially due to DOS's stupid way of drive letter ordering, where primary partitions get higher drive letters than logical drives on extended partitions, so I've ended up with:
C: - primary partition on first PCTask harddrive file
D: - primary partition on second PCT file
E: - logical drive on extended partition on first PCT file
F: - logical drive on extended partition on second PCT file
G: - logical drive on extended partition on second PCT file
This brain-dead-ness is by design with DOS and isn't PCTask's fault!
