Low Level Format, a technique used by Hard Drive Manufacturer to recondition their HDD. There is myth saying LLF will bring old/damaged HDD back to life again but i can ensure you this is not true anymore for any new HDD.
Any HDD build nowadays (IDE/ATA/SATA/SCSI/SAS) have build in chipset protection that will ignore the LLF operation command sending out from the system. This is part of the safety measure of the HDD itself. The truth is, the LLF can now only be done in Factory with specific tool.
However, for those who concern about data security or wish to try their luck to read bad sector, there is a similar method like LLF for it.
We can zero-fill the HDD with a wipe Tool, the tool simply just write every sector with leading zero.
For this purpose, i would recommend Hard Disk Low Level Format Tool (also call Wipe Tool, both does same thing, just name different)
