formating a PC hard drive, doest it erase the DOS command too ?

Answer 1

A Format will erase the Drive, volume, or partition entirely. You cannot format a partition/drive you are currently booted on, so you need to boot off something else.... a startdisk or utility CD for example. When you do this, you are running DOS of the bootdisk.

Answer 2

Yes, formatting the disk erases EVERYTHING. Windows, DOS, Unix, Mac, whatever operating system you are using. You will not be able to boot from that drive again.

Your system will still be running, from the OS that is stored in memory. If you turn the system off, you are sunk, unless you have a boot disk in another drive. Make SURE you have a boot disk before you do this. Of course, there is a protection factor here -- you cannot format the active hard drive from Windows, you have to exit it first.

Unfortunately, there are some viruses that may stick in the boot sector, and you did not fix it. For that, you would need to do an fdisk, which will wipe the last, basic boot information from your drive.

Answer 3

once you format a confusing stress, there are 3 approaches, finished format, speedy format, or Low factor format. an total format runs trough each and each and every of the archives and receives rid of the first letter of each and every report on the disk and scans all empty sectors besides independant of what the MFT (carry close report table says). That takes a even as. a speedy format tests the MFT and purely is going to each and each and every report and receives rid of the first letter, so archives aren't any further readable anymore, the picture of on finished format. A Low factor format is going to each and each and every cluster and writes a nil on it. it really is why some call the LLF, zerofill and also you pick a particular software for that like HDGURU LLF tender you'll detect on-line for loose. observe that a LLF also recovers written undesirable sectors. In speedy or finished format all of your archives are there and could be study through fix softwares and restored except they have been overwritten through recent archives. So, what ever you do, finished or speedy is an similar, that is only a question of ingesting a espresso now or no longer. On a Low factor format you've time for a lunch besides and CIA and FBI can bypass to hell after that. So, make up your concepts and choose..

Answer 4

Formatting a PC hard drive will erase every thing( your saved files, software programs like word, your operating system, etc)

If you format a harddisk, then you will need to install the operating system again!

IMPORTANT NOTE: if you are formatting, be sure you backed up very important files on a cd or floppy, or flash dirve or save it on a different computer!

Answer 5

DOS is so simple it's a part of the BIOS (built in operating system). When you format your computer, you'll turn it back on with the C:\ prompt and a "dir" won't give you anything. Boot up from the window's CD to reinstall it.

Answer 6

yes, it does remove the DOS, so you should format your drive with system transfer option like format /s, this will bring basic DOS utilities required for booting you PC to command prompt

Answer 7

Formatting a PC clears Windows and everything Windows supports, it does not delete DOS, which is a seperate operating system.
