This program is compatible with virtually all hard drives that we can find in the market. In this way, thanks to a very simple interface and a process without risks or complications, we will be able to leave our hard disk as close as possible to the being it has just left the factory. HDD low level format is a free program (although with limitations) that will allow us to clean all sectors of a hard drive and fill its information with "0" and other random data. But there are techniques equivalent to low level formatting that will allow us to fill all sectors of the hard drive with "0" and erase the data to leave the drive as new from the factory.Īnd the most popular program for this is HDD Low Level Format. A user cannot LLF a hard drive like that just because. However, this technique could only be performed by the most advanced manufacturers or technicians. This type of formatting, moreover, not only deletes data and makes recovery impossible (or very complicated), but it can also help us solve hard drive issues, for example, sectors that have been damaged or corrupted.Ī low-level format in the past was equivalent to leave the hard drive as new from the factory. In this way, the data that was saved on the hard drive cannot be recovered, since all sectors of the disk have been emptied during the process, filling all sectors of the disk with "0". Unlike a normal format, which only erases the file system, low-level formatting erases every sector on the hard drive surface. In this way, with the help of specific software, these data could be recovered relatively easily. As we already know, formatting a hard drive does not erase the data saved on the drive, but rather deletes the file system and marks all of its space as "available" while waiting for other data to take its place.
