Low-level formatting means to outline the placement of the tracks and sectors of a hard drive, it writes the
control structures that define where the tracks and sectors are. It is often called as “true formatting”, because
the low-level formatting really created the physical format.

High-level formatting is just a process of writing the file system structures on the disk, it only rewrites the
partition table, so it won’t physically damage or destroy the data stored on the hard drive. High-level formatting
usually includes two types: "quick format" and "full format".
Then you can see it is possible to undo format after you used high-level formatting.
Tips: If you want to undo the format of a hard drive, please ensure the hard drive is not re-used or overwritten
and no physically damaged.
Professional technicians must have the knowledge about how undo the format of high-level formatting, for example,
they can use undo format commands to recover their data. If you do not have much knowledge of the computer, what
will you do? For a fresh man of computer there are a few data recovery programs available, just like DiskGetor Data Recovery.
