After the conversion the last 8Mb of disk space is reserved for the future conversion of the disk from basic to dynamic.
In some cases the possible unallocated space and the proposed maximum volume size might differ (e.g. when the size of one mirror establishes the size of the other mirror, or the last 8Mb of disk space are reserved for the future conversion of the disk from basic to dynamic).

Dynamic to basic conversion of the disk, comprising of system volumes, takes a certain amount of time, and any power loss, unintentional turning off of the machine or accidental pressing of the Reset button during the procedure could result in bootability loss.
In contrast to Windows Disk Manager the program ensures:
