Tuneup offers three file shredding methods: Secure deletion, DoD5220.22 and Gutmann method. These are overwriting techniques. Previous replies have talked about overwriting.
Secure deletion (which I think uses the 'Fast' algorithm). This technique gives you 1 pass shredding: your data is overwritten with zeroes.
DoD5220.22 gives you 3 pass shredding: 1st pass: your data is overwritten with zeroes, 2nd pass: overwritten with ones and  3rd pass: with random bytes.
Gutmann gives you 35 passes (which involves overwriting data 35 times, with 35 different types of new data)

If i format a system in order to installed a new window,can all d previous file/program dat ve been formated be retrieve by d file recovery software. 2ndly,is it posible to retrieve,delete or add file through MS dos.

If deleted files remain on the HD someway or the other, what then happens on a formatted Disk

the most educative post in recent times. But it seems a lot of you have got skeletons on your hard drives

Wallie:

You already got the answers. The address of the deleted files becomes available to be re-assigned. The file is still there but the OS does not know its location. There are tools to recover deleted files and also tools to completely delete files by writing on the same address a number of times.

For example, if your file occupied address 0x1 - 0x9 and you delete the file, that means that the OS can write new info to that location. If a new file is written to that location but you only used the first 2 adrresses, i.e., 0x1 and 0x2, then you can only retrieve part of the original file written to 0x3-0x9 fully intact.

I say fully intact because addresses are usually 32 or 64 bits and just because you write to a location do not mean that you're using all the bits available to you. For example, 1 is just going to occupy the first bit of address 0x1 while FFFF will occupy all the bits.

Highly educative

good.

If they don't completely go away then how do you get rid of them for good?

They would be sanitized/degaussed. Even at that, there are state-of-the-art recovery tools with corporations such as the fbi and cia to recover data from the disks. The best way to get rid and protect information on the hard disk is to totally destroy it by incineration.

Well, me pastor say that if it was a good file it would go to e-heaven where it is possible to retrieve them using special document-soul-retrieving software. But if it was a bad file, such as, well, you know those bad files, and those of you who view them shall follow your files to where they go!!
Sorry for the deviation.
Bad files would go to e-HELLFIRE!!! Nothing you do can retrieve them. Hahahahahahahahahahahahahahahhahahahhahahahahahahahahaaahahahah

nice piece of info from every contributor,
therez been a great deal of addition to my existing knowledge
THANKS

i'm learning

if u erase pencil writings.where does it go??

it joins the dust

During the good old days of MSDOS when a file is deleted; the first character of the filename is changed to hex E5; so what I usually do to recover such file was to transverse the FAT and as soon as a filename whose first character is HEX E5 is encountered with semblance to the deleted file, I prompt for new filename.

For example

accounts.db after deletion becomes ?ccounts.db

What happens on an NTFS (Windows 2000 – Windows XP) partition when you or the system deletes a file is totally different ball game.

Such deletion can be broken down into
[list]
[li]Moving To Recycle Bin - The MFT entry is modified i.e given a new filename and the file is moved to a special security directory created per user and its original filename stored in the special file INFO2 [/li]
[li]Empty Recycle BIN - INFO2 is emptied [/li]
[/list]

Vista no longer uses INFO2.

Hope this information helps,

house, i need a bulk sms, how can i get any good and cheep one, around Abuja, pls i need ur reply as urgent as possible, wanpele4good@yahoo.com

A common misconception is that the data is actually removed from the hard drive (erased) when you delete a file. Any time that a file is deleted on a hard drive, it is not erased. Instead, the tiny bit of information that points to the location of the file on the hard drive is erased. This pointer, along with other pointers for every folder and file on the hard drive, is saved in a section near the beginning of the hard drive and is used by the operating system to compile the directory tree structure. By erasing the pointer file, the actual file becomes invisible to the operating system. Eventually, the hard drive will write new data over the area where the old file is located.

There are several hard disk utilities that you can find on the Internet that allow you to recover "deleted" files. What these utilities do is search for data on the hard drive that does not have corresponding pointer information and present you with a list of these files. Your chances of fully recovering a file diminish the longer you wait after you deleted the file since the probability that the file has been overwritten increases. Sometimes you can recover portions of a file that has not been completely overwritten.

pls, peeps ! what now happens to the file when you eventually format the drive?

black hole

Your deleted files are still there. Unless you bring out your HDD and break them into pieces and burn them. There loads of programs that can fish out all datas that has existed in any PC or Mac.

What if you format your computer and install a fresh OS. would your files and folders still be recoverable? If yes, pls any free software i could use?

My toilet

trash, i guess
