5.7 Selecting the medium

Note: The MultiDelete option can be activated in all editions of HDShredder, even in the

Free Edition. This can be used to check in advance which speed can be achieved on a cer-

tain system by using the Enterprise Edition. Please keep in mind that the achievable speed in

this case strongly depends on the interfaces used (most suitable: IDE, SATA, and SCSI) and the

drive combinations (only use master drives with IDE).

5.8 Selecting the deletion method

The dialog page ‘Deletion method’ provides different deletion methods to be used for different

areas of application. These procedures are grouped into three categories. The category Auto-

matic allows you to perform a simple and secure deletion fast and easily without needing any

further detailed technical knowledge except of the criteria of time and security. The category

Standards is designed for users required or wanting to fulfill certain deletion standards for

themselves or for their client. In the category Custom, you can define all details of the deletion

method by yourself. Further information concerning the functions of the different deletion

methods can be found in 6.5 Deletion methods.

5.8.1 Automatic

Select the desired option:

• Fast: One run within the shortest time possible gives you the security that no one can view

or recover your data with the help of normal means.

• Medium: The best possible combination of security and time.

• High security: Deletes data using an internationally recognized method which is also con-

sidered to be secure against the data recovery in the laboratory.

By clicking [Next] at the right bottom of the dialog box, you confirm your selection and come

to the next step.

Note: If you want to have the highest security possible but you are not sure whether the

available time is sufficient, you can simply use the deletion method High security. In case of a

lack of time, you can abort the process at any time. This will not affect the deletion progress

attained up to that point of time negatively and you may achieve a higher level of security.

Example: You achieve a higher security aborting a High security (7 runs) process after 4 runs

than only using method Medium (3 runs), but letting it run till the end.

5.8.2 Standards

Simply select the desired standard from the list displayed. By clicking [Next] at the right bottom

of the dialog box, you confirm your selection and come to the next step.

5.8.3 Custom

This category offers you a mask where you can define your specific deletion method fast and

easily. A specific deletion method is based on three parameters and a repetition counter.
