General :: Cannot Create Logical Partitions Without Errors

I have run into a Gparted problem that I am not familiar with. I've never seen it before.

I cannot create logical partitions without errors or not at all. I have two choices:

1) not checking 'round to cylinders' - I will get an error* and it will not partition

2) check 'round to cylinders' - it will partition but I will also obtain 4MB of unallocated space (each time)

This applies to Primary partitions, too, I think. At least, #2 will happen.

Imho, this is ridiculous. Why would I retain 4MB of unallocated space? In other words, the two choices above are not choices.

The error message doesn't explain much if anything either. *"Unable to satisfy all constraints on the partition"
