Since the way of writing data on SSD is completely different from that on HDD, you cannot use the "zero fillings" method for low-level format.

The ways to low-level format SSD in Windows ►In order to protect personal privacy, you need to delete all data from it without recovery. ►If you want to reinstall the Windows system, you can also perform low format, because the conventional format cannot really clean the SSD, and it will actually damage the service life of the SSD. If you want to restore it to its original performance, you can perform low-level operations on it
►As the time of use of the SSD becomes longer, its performance will be greatly reduced. Generally, if you want to perform low-level format operations on SSD, it means that your SSD has the following conditions: Common SSD brands are Samsung, Kingston, Seagate, WD, Intel, SanDisk, etc. It is a smaller and faster running speed, but the price is higher than HDD Therefore, due to the excellent performance of SSD, more and more users want to use SSD and reformat SSD. It consists of a control unit (FLASH chip) and a storage unit (DRAM chip). It is a larger and slower running speed.Ĭompared with traditional HDD, SSD is made of a solid-state electronic memory chip array. The HDD is mainly composed of a disk, a head shaft and a control motor, a head controller, a data converter, an interface, and a cache. Hard disk drives (HDD) and solid-state drives (SSD) are both data storage devices, but there are differences between the two. Each SSD and HDD has been low-level formatted before leaving the factory. The low-level format is a necessary prerequisite for the high-level format. Each sector is divided into identification part ID, interval area, GAP, and data area DATA. The low-level format (LLF): refers to the hard disk is divided into cylinders and tracks, and then divides the tracks into several sectors. The format we usually talk about is the high-level format. Just clear the data on the partition, generate boot information, initialize the FAT table, mark logical bad sectors, etc. The high-level format(HLF): refers to reformat each partition after the hard disk is partitioned. Formatting is divided into the low-level format and high-level format. Formatting can delete all files in an existing disk or partition. ▐ What is low-level format?įormatting is actually the operation of initializing a disk or disk partition. Understanding the following two points will help you understand the low-level format of an SSD and let you operate more easily. Question from LINUS TECH TIPS Things you should know before SSD low-level format Does anyone know if it is possible for me to somehow do this to the same drive on which the OS is installed?” I would like to low-level format it several times (I heard it has to be at least 20 times on SSDs) to make the files unrecoverable.
