_DISK_EXTENT structure

Description

The DISK_EXTENT structure contains information defining the location and length of a volume extent on a disk.

Members

DiskNumber

Specifies the number of the disk that contains this extent. This is the same disk number that is used to construct the name of the disk (for example, PhysicalDriveX or HarddiskX, where X is the disk number).

StartingOffset

Specifies the offset, in bytes, from the beginning of the disk.

ExtentLength

Specifies the number of bytes of this extent.
