Options are Select All, Name, Serial (the disk serial number), Disk Size, Pool (where the disk is in use), Disk Type, Description, Model, Transfer Mode, Rotation Rate (RPM), HDD Standby, Adv.

Abort stops the disk wipe process. At the end of the disk wipe process, a success dialog displays. Close closes the dialog and returns you to the Disks screen.
