Scan for missing volumesWhen a volume is deleted from the partition table, or the partition chain
gets
corrupt, it will be inaccessible but the corresponding boot sector may remain
intact. Partition scan procedure looks through the volume locating such an
"orphan" boot sectors. The parameters of the volume are then considered for each
of these boot sectors, and the volumes that look reasonably valid are added to
the partition view.
To perform a scan, right click anywhere in the partition list, then select
"Scan for missing volumes".
Be advised of the two limitations of the process
- Partition scan might bring up a number of "phantom" volumes. This is
because boot sectors are occasionally saved in the data area of the volume
(for example, AUTOCHK.EXE Windows NT file system checker contains several
boot sector templates in its code). ZAR can not determine if the
boot sector is genuine or represents a "phantom" volume, so everything gets
shown for your review.
- RAID or spanned volumes cannot be located this way (with the exception
of RAID1 "half-mirror" members), since volume boot sectors do not contain
any information about RAID array layout. First member of the RAID or spanned
volume (actually containing the boot sector) will typically be found and
listed, but attempting the analysis run against the volume defined in such a
way will fail.
