I'm ready to sell an old XP desktop, what's the best way to wipe all personal data, boot the OS install and start again?

TIA:badpc:

Reinstall xp, not forgetting to reinstall all motherboard and hardware drivers,
alternately just remove all data from personal folders (my docs/pics/music etc), or go into user accounts, make a new user/administrator and delete the original one (not sure if that'll work tho :))

May wanna look into a wiping software. They can be recoverable if you do a simple delete.

Use dban, a disk wiping utility to clear your hard drive before reinstalling Windows.

recovering data after a format isn't cheap and easy, so i doubt anyone would bother :p

just reinstall windows and drivers as per above.

If you want to be sure take the advice from FoxyMX.

Best way is as per what foxy suggested - there are many free programs these days that take very little skill to recover data even from a formatted drive.

Dban looks the business, I will investigate further.

Thanks for the replies!

I feel you have over estimated the cost/ease of data recovery.


I have done a security project on this, I have recovered about 1TB of data from old hard drives off trademe, using free tools, only an hour per drive.
many drives purchased at $5 or $10 each.

found emails, photos, web history, legal documents. passwords.
I even found a chain of emails relating to costs of running one of NZ's most well known companies....


a format wont stop even basic data recovery.

the re-install of windows will trash a good chunck of the drive.
but the other chunk will still have data that can be recovered.

DBAN and then a re-install is the best answer.

The specific US Military standard which I cant find at the moment used to specify:

7 times, delete all partitions, recreate partition, and write full with multiple random caracters.

before allowing usage of drive in another Millitary Dept.

all drives are destroyed when computers are disposed off by the US Military.

http://www.sharewareconnection.com/flobo-wipethedisk.htm

are free or limited free and claim to conform to us military std.

If you use them in the 7 x 7 metheod there should be no problem

If your really concerned take the paranoid us example and destroy it.

This is why you see so many laptops today 4 sale with NO Hdd.

Most of the dell and hp "Refurbished" Laptops are X US Govt, refurbished by adding a NEW hard drive and testing them.

Luckily no state secrets or cc numbers on this pc, only idle ramblings to family and friends by email etc.

But better to be safe than sorry! No telling how much grief someone could cause with my PCworld forum password!:eek:

I use Ccleane rand have it set to DOD 3 passes, not sure how well it performs but is OK by me as my HDD's get reused all the time at home for ongoing projects

DOD 3 pass is what we use to wipe our corporate customers HDD's (WipeDrive Pro these days).
The average man in the street will struggle to recover data after 3 passes.

I did read that.

At the end you say economably viable and I would not bother but others do just because they can.

Not to mention most people aren't interested in your family snaps and boring files.

i think you read it wrong...

it's just a warning that you should be very sure before you do a secure wipe, because it is very near imposable to get data back after you push the button.

I do an Fdisk,[& kill everything] and subsequently reformat with FAT32 /unconditional/system.
The system allows a clean new install subsequentally.

Which does not mean data can't be recovered.

and this is fine if you are just re-using the disk for yourself.

but if you are giving / selling the disk to some else, then I would look at doing a secure wipe first.

Agreed.

Makes sure all the porn downloaded by accident can't be recovered.
