Help set my friend straight.

This is ridiculous and i know you cant but heres what he thinks.

He thinks that anything that you've ever deleted from your recycle bin can be retrieved. His argument was that once you delete something where does it go? and he still maintains that it must still be in your computer somewhere.

The worst thing about this is that a lecturer told the class this in college.

It's true. When you delete the file it deletes references to it. It doesn't delete the data. The data blocks are freed up and will normally contain the information last used but will get overwritten.

Actually there is hardware out there that can retrieve a file that has been wiped from the disk or overwritten.

So your friend is right.

afaik, if it hasnt been written over by new data its still on your hard drive. Deleting data just removes the references to the data and tells your os that the segment of the drive is free to write on. There is software available that can read a deleted hard drive.

Hobbies, you just beat me to it.

if you have such a program called norton unerase or the likes, it can be done

yep what Hobbes said, but in addition there is a defined standard bit sequence for "deleted space" on hard drives.. e.g. space which does not hold any data at all except the information that it is deleted...
Recycle Bin in no way sets this bit sequence.

also its always easier to recover data from frequently defragmented drives due to the greater chance that all data blocks will still be intact, so if your into your dodgy porn then its best to keep it all messy

and sorry if im confusing. ive been trying to understand how quantum incoherence leads to conciousness, as found on some happiness thread

Oh F3ck.....

pah dont do that. just tell him he didnt explain himself properly and you thought he was refering to space rabbits.

Hobbes

After reading all these, go back to your friend and tell him he hasn't got a clue what he's talking about. That will make you manager material.

ahhh... good old "undelete" and "unformat" in DOS, eh?

Yes, utterly preposterous.
Bah, don't blame yourself, blame the spunk-monkey who told you - "when things are gone from the recycle bin, they're gone forever".

I've met people who still strongly believe that folders in Win9x are "indefinitely expandable", people who should know better at that.

What is the limit? I think DOS had a 256 character limit for all the character in all the directory path (I think including slashes). Hard drives just weren't as big back them.

I'm not sure of the exact limit, but it's there, even in Win98(FAT32) with my 30Gig harddrive... try it out if you want.

Stick these lines in a batch file (.bat)

cd \

:loopme
md test_dir
cd test_dir

goto loopme

(It's very basic, but it'll do the job)
Once you run the batch file, it'll make recursive folders until it can't make any more... give it a few seconds to run, then kill it... open up a file manager, and go to the very last folder... try to make a file or sub-folder.

You'll probably never need such a deep directory, but the limit is there.

Proving the data hasn't been overwritten since the references to the data were deleted.

Sorta off topic this.
But if ur working on a file say for example a .psd photoshop file,
its using a temperate file to make changes on right?
(this has happened me sooooo many times i've lost count ) lets say i've been working on the file for a half a hour without saving it and the putter crashes,
normally i go "**** SAUCK ****ING PEICE OF ****" and storm off for a smoke
come bak and redo the work, is there a way i could retrive the temp file photoshop was using to make the changes and open it?

would save me so many headaches

Megatron

points adn laughs at Havok !!!!!
sorry just the whole fe<king the system out of it... it brings back so many memories !!!



speaking of a smoke i think i will thank you
