Subdisk Properties
Name
Subdisks on a disk are assigned numbers in a sequence, such as 1-01,
1-02, 1-03 or 12-01, 12-02, 12-03. The subdisk number is an internal
number generated by the program. There is no particular significance to
the one or two digits before the dash except that, for any one disk, the
first one or two numbers identifying its subdisks must be the same. The
numbers after the dash represent a number for the subdisk within the
disk. Thus, if the subdisk was the first one created for a particular disk,
it would have 01 after the dash, the second disk created would have 02
after the dash, and so on.
Size
This field displays the size of the subdisk.
Column
Column displays the column that the subdisk occupies in the volume.
Striped and RAID-5 volumes have multiple columns.
Disk Offset
This is the offset where the subdisk starts on the disk. The reason this is
included in the Properties window is because for a subdisk to be split, it
must be a contiguous to the subdisk next to it. By looking at the offsets,
you can determine which subdisks are contiguous.
Plex Offset
This is the offset of a subdisk within a plex. It shows the distance from
the start of a plex to the start of a specific subdisk. The first subdisk
within a plex will have an offset of "0." The second subdisk will be offset
by the size of the first subdisk.
