Removing HD data permenantly.

I wish to pass on an old Dell laptop using Windows 7 to a family member. Is it possible to remove safely all data and passwords whilst leaving the operating system and some of the programs installed in a workable state? I am a little wary because of instances where supposedly scrapped computers have had supposedly 'deleted' info reread from the HD. Any suggestions/help would be appreciated.

When you delete a file it only takes the name away. The file is still there, until it is overwritten, but without a name so you can't see it.

If you download and run Eraser from click here you can overwrite all the unused space so any deleted files cannot be recovered. The options tab in the programme will let you choose how many times you want to overwrite the space although, depending on what you choose, this will take a little time.

Setting it Back to factory settings maybe do the trick.

No it wont. Doing that first is sensible and then run Eraser..

If the OP does a factory restore he will lose any installed programmes.

Eraser is secure. I have tested a disk by recovering deleted files . After running Eraser the same programme could not find any deleted files to recover.

Thanks very much for your input - I will follow the Eraser route which I think will give me the best outcome. Whilst I have the original system discs, I'm not sure of the outcome of a factory reset since the original HD has been replaced.

If you have CCleaner there Is a similar overwrite tool in that. Takes a long time for the 3 or 5 pass option.(After you have deleted the data etc you want)
