6.2 Automatic troubleshooting
rors, which occur during the verification run, are also counted as verification errors. Therefore,
the number of verification errors gives you absolute information on the amount of sectors
where secure deletion could not be confirmed. In case of an error-free deletioning process,
HDShredder should not report any verification errors and signalize a 100% conformity with the
deletion patterns written.
6.3 Deleting a sector area
In case of an area deletion, the medium is not used as a whole. Only a partial area of the selec-
ted medium (drive or partition) is used for the deletion.
6.3.1 Usage
The dialog page Options provides the possibility to specify an exactly definable sector area
(5.9.3 Options for the medium). To specify a sector area, activate the check box Sector area
and enter the starting (from) and the ending (to) sector of the area to define. These sectors
are interpreted as the first and the last sector of the are, i.e. they are included with the area.
Note: The sector counting starts with with ‘0’ (= 1
st
sector of the medium). Accordingly, all fur-
ther sector numbers have to be decreased by 1, too (e.g. from = 0, to = 99999 defines the
first 100000 sectors on the medium as an area).
Warning: You should not conduct an area deletion unless you are completely aware of its
functioning and possible consequences. A sector area, which has not been defined with ex-
pertise may lead to undeleted data remaining on the medium.
6.3.2 Functioning
The sector area is always subordinated to the selected medium (drive or partition) and is inter-
preted relatively to the starting position of the medium. Instead of using the whole medium for
the subsequent deletion process, only the defined sector area will be used. Compared to a
normal deletion, the only difference is that instead of deleting the whole drive or partition only
the defined partial area is being deleted.
Example: The values from = 0, to = 31 define an are of 32 sectors. In case of the type of the
medium is a drive, the declaration refers to the first 32 sectors on the drive. In case the type
of the medium is a partition, the declaration refers to the first 32 sectors of the partition and
may be located at an arbitrary position of the drive (depending on the partition table).
6.4 Mass deletion (MultiDelete mode)
In case of a mass deletion, multiple target media are being deleted at the same time. As a res-
ult there is a huge benefit regarding time and performance, since multiple media can be de-
leted at the same time.
