High level format(HLF) is a process of initializing portions of a hard drive, SSD, SD card, USB flash drive. and reinstall the file system structures on the drive. But high level format does not erase all the data on the disk, it just erases the “path” to the data, and rebuilds the existing data structures, such as boot sector. So the data can be recovered after high level format.
High level format is a typical way to erase and recreate the data structure. It actually can't wipe existing data on a drive. So it is usually a preparation work before installing apps, software, or upgrading system. And if you want to completely and permanently clear the data on your hard drive, low-level format should be done. Let’s see what is the difference between high level format and low level format.
High level format vs low level format
Low level format (LLF) is another way of formatting. It is a “real” formatting method. All existing files and data on the disk will be erased with low level format. For instance, write zeros to hard drive is a common way of low level format.
You can see the difference between high level format and low level format as follows.
● HLF is recoverable, while low level format is almost impossible to be recovered. Low level format wipes entire hard disk, which prevents most of data recovery tools from restoring formatted data. ● High level format is much faster than low level format. ● Compared to HLF, LLF makes much bigger impact on disk. Because it would divide cylinders and track on hard disk again, and it can shorten the lifespan of hard drive.
Due to these differences between high level format and low level format, high level format is more widely used in many conditions, like removing write protection, restoring hard drive to full capacity, releasing disk space for new data, being unable to access to external storage device, etc.
Now, we are going to introduce 3 methods to perform high level format.
