What happens to files when they are deleted from te recycle bin and how does certain software recover them?

Answer 1

It's not easily done and it doesn't always work. I used a program called Stomp Soft Recover Lost data, it was nothing to install, it cost about 40 bucks, it took about 3-5 hours to scan my computer for files that have been totally deleted from the recycle bin or erased when the computer was reformatted and windows was installed.

I was able to recover a lot of photos and media type files, anything like document, either came back in pieces or didn't come back at all.

Answer 2

Imagine your video collection. Imagine that there was a particular tape you decided you no longer wanted to watch anymore. So you took the label off and replaced with a label which said "Blank".

That video is essentially blank. Okay, so it isn't really blank but for all intentional purposes it is. You can record onto it as if it was a blank cassette new out of the pack.

Now imagine that you realised that you wanted to see what was on that tape again. You could put it in the machine and see what was on it. If you wanted it back you could write a new label on it couldn't you?

When you delete a file - even from the recycle bin - all you are doing is telling the computer that that part of the hard drive is empty and it can put new stuff there.

Recovery software will go and look at that part of the hard drive to see if it really is empty or not. It will recover any files it finds by telling the FAT (the file allocation table - the list of where things are on your hard drive) that there actually is something there. If the computer has already used that space for something else, then the recovery software wont find it.

When you format your hard drive you tell each sector of the disk that its empty, where if you do a "quick format" you are telling the FAT that the rest of the hard drive is empty

when files are deleted the are simple removed from the file allocation table the table that keeps track of the file and where it starts and ends on the disk...when you delete the file is removed from the list but the actual data is still on the drive...

certain programs can get to them and recover them if the space the file was in has not been over written... this was done since 98 i beleive and then had the undelete command

the file is still there on the drive until data needs that space and it is over written...

Answer 4

You have to understand how the hard drive keeps track of file addresses by means of the File Allocation Table.

Think of your hard drive as a ware house full of boxes. No you save a file by putting it in one of those boxes, and making a record of it on a master table of contents. No you want to erase one of those files. Instead of going out to that box and removing the file, you just erase the record of the file ever being there on the table of contents. The file still exists, but you cant get to it easily unless you go search through every box.

In that short story, the boxes are the hard drive memory addresses, the table of contents is the File Allocation Table, and the search of every box for a file is a data recovery solution.

Answer 5

The files which are deleted are stored on the same physical partition and place but the road to which the computer has to go to read them is erased and if you don't write anything on the same place they are staying there!!! BUT if you write a new fail for example onto the same spot the previous fail is OVERWRITTEN and the content is erased!!! THAT'S the very basic because if you want to know more write again and will write you in details OK? Have a nice DAY!!!

Answer 6

They are still on your hard drive only they have been made invisible.
The software scans for these files and recovers them by making copies and placing them into a folder for your review.
If they have not been overwritten then no reconstruction is necessary and they remain in the same condition as when they were deleted.
If they have been overwritten then special algorithms in recovery software are used to replace the missing pieces so that they can be read.
The more times they are overwritten the less chance that they can be recovered.

Answer 7

Try Restoration, see below - this will recover your files and its quite quick. I think you can totally delete files as well. Big plus - its free.
If you really want to totally delete (overwrite the file with 1's and 0's) then get a utility like Evidence Eliminator.

Answer 8

the markers are deleted from the files ... the info is still there but the system is open to write over them ... so recovery software can find the information and remark it if it hasnt been written over yet ..

Answer 9

cause the file isnt actually gone, just the space on the hd that holds the info is free to be written over.
