Different availability in toolstar®shredderLX and shredderWIN
The program toolstar®shredderWIN does not support all methods of toolstar®shredderLX - especially in the areas of firmware commands. This limitation arises from running under Windows, which does not allow unlocking hard drives. However, classic overwriting is also possible with toolstar®shredderWIN. With toolstar®shredderLX you always have access to all methods and a complete one Automation of all processes.
Firmware-based sanitization methods
Firmware-based methods run internally in the hard drive and can therefore also delete areas that lie outside the actual data area. Depending on the method and hardware, this includes, for example, cache memory as well as swapped blocks or security keys. When the erase process starts, the disk controller sends a direct erase command to all NAND blocks within the disk. The hard drive then deletes as many NAND blocks at once as possible. During the process, the hard drive uses the maximum allowed energy to delete as many blocks as possible at the same time. Due to this parallelization, these operations are performed extremely much faster than classic overwriting and are just as secure, if not more so. In contrast to classic overwriting, this process can no longer be canceled. Even if the hard drive is simply unplugged, the process will continue the next time it is turned on until it is terminated. The hard drive is also not fully usable during this phase.
Combined erasure for maximum security
Even if the firmware-based deletion methods basically delete all data and more and are even faster, you should always use a combination of classic overwriting (international standards) and one or more firmware-based methods. This combination means you are fully protected technically (combination) and legally (international standard method). All methods carried out are always listed in the deletion certificate. For example, if you run the Santitize: Block Erase and BSI 3x method on an ATA SSD, you will receive the output: Delete method: Sanitize: Block Erase, BSI 3x.
Verification after sanitation
Verification after deletion performs a check of the data on the hard drive after deletion, depending on the setting or default. What is written is compared with the data actually on the hard drive. If there is a discrepancy between the written data and the data actually on the hard drive, you will receive an error.
We recommend that you always carry out a sample check at the beginning and at the end with a percentage of 1% or more. This optional implementation is also mentioned in the deletion certificates.
