Hello,
I use virtualbox window of seven.
I have a question concerning the capacity of hard disk.
I create a dynamic disk 80GB, but when I look in the window exporateur, the capacity of dique is 6.60Go?

This is it normal?

Thanks for your help

The capacity of a partition is different than the capacity of a disk. So, assuming that you are looking at a 6GB partition, yes it is normal.

VirtualBox has no control over how a guest OS partitions the disk, or what filesystem it formats it with.

I suggest that you double check your numbers, and what exactly you are looking at. VirtualBox has no known bug in this area.
