More about formatting external hard drive

So-called format is what meaning, as you all know more or less a bit, once the disk is formatted, the disk file will be emptied. This is because format refers to an operation to initialize the disk or partition in the disk. This operation usually leads to the deletion of all files in the existing disk or partition.

Let's give you another popular science. Format is also divided into low-level format and high-level format. How to distinguish between low-level and high-level? It depends on their definition.

The so-called low-level format is also called physical format. Low-level format is to re empty the contents of the disk, return the disk to the factory state, divide the cylinder and track, and then divide the track into several sectors. Each sector is divided into ID, GAP and Data. At the same time, low-level format is a work before high-level format. Each hard disk is low-level formatted before leaving the factory. Low level format is a lossy operation, which has a certain negative impact on the life of the hard disk. Low level format can only be used for one hard disk and cannot support a separate partition.

What about high-level format? Since it is high-level, of course, the advantages outweigh the disadvantages. high-level format only clears the data on the hard disk, generates boot information, initializes the FAT table, marks logical bad tracks, etc., and will not have a negative impact on the service life of the hard disk. Therefore, it is recommended to use high-level format when formatting the hard disk.
