whats the difference between quick and full format (formatting a hard drive)?

Question

Technical answers would be good

Answer 1

"A full format also performs a chkdsk along with removing the table, a quick format just removes the table."

"full scans for bad sectors. i always do a full format. it doesn't take too long on my small windows partition"

"another difference between quick format and full format is that full format removes everything, while quick format only deletes the root folder and FAT (file allocation table). deleting the fat has the effect that your pc doesn't find the files on your hard disk any more, but they are still there. but because your pc doesn't find them any more, it just writes over them... :)"

Answer 3

Quick format erases the first 25 sectors and the last 25 sectors of the hard drive so that you can install the os quicker shorter format waiting time.
Full format erases all sectors on the drive so longer formatting time.
Quick format is the better option because at the instalation the sectors on the disk are over writen any way so your install is twice as quick than using the full format which takes longer.

Answer 4

A full format will help to weed out any bugs or problems on the hard drive. Better to do full format to NTFS as it's more secure. Formatting turns the 1's in the binary code of the data into 0's so that they can't be seen.

Answer 5

Hi Ben

Quick format blanks out the index of the hard drive and lays out some minimum structure on the rest of the disk. That's why it's fast, it's only actually changing about 1-5% of the contents of the disk.

Full format writes out a new index, then tests the surface of the entire drive to see if it's reliable enough. This takes much longer but you can be sure that you've got a good drive. If it finds any bad space, it keeps a record of it in the bad space table.

Quick format is bad news on a new drive - some drives have entire surfaces that are unusable, so the last 25% of your hard drive might be totally useless. If you only quick format, you might not find out for a long time. Any time you saved during format you'll waste later on reinstalling everything again.

Of course, if you've been using the drive for ages and you know the whole thing is fine, quick format is great.

Hope that helps,

Answer 6

A quick Format will simply allow the Hard drive to be written over and before the harddrive is written over, the data (with the correct software) can be recovered. With a full format the data is much more difficult to recover as the hard drive has been returned to almost factory settings. Beware when formatting drives, you will lose your operating system and all installed software!!

Answer 7

FAT32 is a common file system format used on computers of all types. FAT32 has several benefits over other common file systems; it can be read and written to from nearly any operating system and it has no built-in security, which makes it easier to work with. While FAT32 is widely supported, it is not often implemented as the default format on most machines. Windows machines generally default to the NTFS system, Linux systems generally use the Ext4 system, and Apple machines use the HFS Plus system. When sharing external drives between different computers, it can be advantageous to format the drive using the FAT32 file system. Learning how to format FAT32 drives is a fairly straightforward process. However if you buy an external hard drive its format will originally be NTFS but it is easy to change

Answer 8

a full format scans every sector on the disk to make sure there is nothing wrong with the disk, while a quick format does not.

Answer 9

Quick format is "none distructive" it doesnt take everything off
Full Format is "distructive" it wipes the hard drive completly and puts on a new fresh installation of Windows or what ever it is you use

If you make informed decisions and approach your penny stock investments with the same thoroughness that you’d use in your other investments, you too can unlock a whole lot of profit potential. Learn here https://tr.im/wvQ37

It’s absolutely true that penny stock investors can make very quick gains. Synutra International, Inc. (NASDAQ: SYUT) is a great example of a penny stock. This dairy-based, nutritional-products company has jumped from a little Bulletin Board operation to a billion dollar corporation. The company finally graduated from Over-the-Counter status to the NASDAQ Stock Market bringing with it 113% gains in less than two months.

This happens all the time and it’s how some of the best investors in the world became the richest investors in the world. Buying some shares for pennies on the dollar and selling at $10 or $20 is possibly the fastest way from being a hobby investor to a super investor

Answer 11

A common misconception is that you will have to be a financial and business expert in order to successfully trade binary options. However, this is not true at all. Learn here https://tr.im/Hl2xm

Perhaps it’s true when it comes to traditional stocks trading but definitely not true in the case of binaries. You don’t have to be an expert to predict the movement of certain assets.
