HDD LLF: how to low level format the Hard Disk

HDD Low Level Format is a free software tool ( for personal / home use only ) that allows the Low-Level Format (LLF) of hard disks (and mass storage devices in general).
What is LLF
"Typically this involved subdividing each track on the disk into one or more blocks which would contain the user data and associated control information. Different computers used different block sizes and IBM notably used variable block sizes but the popularity of the IBM PC caused the industry to adopt a standard of 512 user data bytes per block by the middle 1980s. " Source Wikipedia English

PERSONAL EXPERIENCE :
I used HDD- LLF for low-level format an external drive connected with USB no longer wanted to learn to operate and above who do not " want to be" formatted by Windows. With both Windows XP and Seven, the format utility (which try to format only high-level) returned an error message and did not proceed . With HDD- LLF I managed to break the deadlock and then, through the utility of Windows XP " DISK MANAGEMENT " , I was able to format ( high-level) disk with the NTFS file system and now it works !
