What is low level format? & What is high level format? give me details and how to do this?

Answer 1

Low level format is done through the manufactures DOS (Disk Operating System) each hard drive manufactures low level format is different .... High level format no such thing.... Normal format is also done through DOS, or windows system disk when installing windows One would need to know DOS system before using it

Answer 2

A low-level format is when you go through your hard drive and set every single bit to a zero, effectively restoring the drive to nothing. To do this, you can use the Format command in Windows (right click on a drive in My Computer) or the Windows install program (NOT using the Quick option) and it will write your entire hard drive to 0's + the necessary basics to store files.

A high-level format is when you simply delete all of the files from your drive using Windows Explorer or some kind of quick format software. Typically this leaves the files where they are and tells the operating system that part of the drive can now be written over.

It should go without saying that both of these procedures will cause a lot of data loss.

Answer 3

High-level format
Method of formatting a hard disk drive that initializes portions of the hard disk drive and creates important file system areas on the disk. A good example of a high-level format is using the format command in MS-DOS.

A high-level format is commonly done if a user wishes to erase the hard disk drive and reinstall the operating system back onto the hard disk drive. If errors are present on the hard disk drive, or a high-level format is unable to be completed, a low-level format may need to be done first.

* Additional information about erasing your hard disk drive and starting over can also be found on document CH000186.


Low-level format
An initial formatting of a hard drive that initializes the physical tracks on the surface or the internal disks. The drive manufacturer usually performs a low-level format on the hard disk drive before it is released and is not something a user needs to do once they've purchased the drive.

If a high-level format (i.e. running the MS-DOS format command) is unable to be completed on a hard disk drive and/or you're looking for information about how to do a low-level format because of a MBR virus or being unable to delete partitions, a debug routine can be performed on the computer that is often referred to as a low-level format. This debug routine can be found on our debug routine page.

Answer 4

low level format is overwriting the entire harddisk with zeros. every piece of logical info including partition and boot record is gone so the OS cannot read it. usually the maker of your harddrive will have a utility for low level format in their web site. to use the disk again you will have to do a high level format, use FDISK to create partition (then set it active for system use) and logical drives. then formating using FORMAT. of couse you'll need a DOS bootable disk with those utilities.
