Subdisk properties
Note:
The Size, Disk offset, and Plex offset fields have pull-down lists that let you select the units you want the number to be displayed in (Sectors, KB, MB, GB, or TB).
The properties are as follows:
Name | In the screen captures showing subdisks in this chapter, you may have noticed that the 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 a 01 after the dash, the second disk created would have a 02 after the dash, and so on. |
Column | Column displays the column that the subdisk occupies in the volume. Striped and RAID-5 volumes have multiple columns. |
Size | This field displays the size of the subdisk. |
Disk offset | This is the offset where the subdisk starts on the disk. This is included in the Properties window because for a subdisk to be split, it must be 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 has an offset of 0. The second subdisk is offset by the size of the first subdisk. |
