There are two types of hard disk formatting possibilities, low and high level formating. High level formatting is the widely known formatting that erases data on the disks while low level formatting nowadays refers to the reinitialization to the factory settings. One of the major differences between both types is that data can successfully be restored after performing a high level formatting of a hard drive.
This is why experts suggest to either overwrite the hard drive with random data before formatting it or running tools like Eraser to erase all data on the hard drive.
The HDD Low Level Format Tool will low level format a hard drive erasing the whole disk surface in the process which has the result, that it is impossible to restore data afterwards. It supports SATA, IDE, SCSI, USB, FIREWIRE and Big drives (LBA-48) and the most popular manufacturers Maxtor, Hitachi, Seagate, Samsung, Toshiba, Fujitsu, IBM, Quantum and Western Digital.
I did not try that hard drive software yet because I do not have a spare hard drive lying around that I could use to test it with and I did not want to format one of my hard drives just for the sake of testing it. If any of you do test the software let me know about the results please. Running a recovery tool like Recuva after formatting the hard drive should show us if the data is really not recoverable.
