Deleting files for good

Eraser v5.6 says
"Deleting files doesn't actually destroy all the data--it just makes it harder to find. To make sure those files are good and gone, you need to overwrite them with a tool like this one."

What about re-formatting a PC? Does this completley remove files for ever?

no re-formatting does not remove files forever they can still be accessed.You need a tool that will overwrite them many times

As far as you are concerned, yes. As far as a determined snooper is convcerned then, no.

Have a look on your drive manufacturer's website for a zero write program.

Even then...

just as I thought.

I have read about a program in PC Advisor that writes over the disk about 40 times but I can't remember what it's called. Does anyone know what it's called. And is it free?

hypothetically speaking, (and I realise that this may be impractical with a HDD that may be larger than, say, 40 gig,) filling the HDD up with audio files?

I understand that if there is data on a HDD and that data is "deleted" the data is still there... However, lets suppose we have a 10gig HDD, that has 6gig of files on it. If those files are "deleted" they may still be accessed, (in the correct hands, with the correct software), until the data has actually been overwritten. If you were to copy some audio cd's, (it would probably take about a dozen), onto the HDD, this would have the effect of overwriting the previously "deleted" data, making it unrecoverable.

You could then "delete" the audio files, and reformat the HDD. In theory the audio files would still be recoverable, but the previous data wuld not. I presume this achieves what is required?

(Note that I only suggest Audio CDs as a means of taking up the HDD space quickly and easily. The pertinent point is to fill up the HDD space so that the space taken up by the original "deleted" files is overwritten. Any type of file would do.)

As usual, I'm open to correction. In fct I'd welcome a rebuttal, with explanation, if I've got it wrong!

Interesting theory but I think that the small company that I'm doing this for would prefer a simpler approach.

There's a program on Norton Utilities called "wipe info" that claims to do the trick..

'Spybot' in its tools section has a program that will over write as many times as you want chosen files.

Have a look in the advanced settings in SpybotSearch and Destroy. It has a secure file shredder tool which is free.

The only sure way to clean a disc is to deguase and the cost for most would be unaccepable

thanks for the feedback.

I have got sypbot - i'll check the advanced settings
