I have a fairly new Toshiba laptop that I no longer need and am going to give away.Before I do so I want to scrub the harddrive clean. Does anyone have any experience with programs such as Drive Scrubber from Iolo?
Or can you recommend one?

Thanks!!:)

Formatting does not eliminate all the data on your harddrive.

Does that Drive Scrubber leave the OS on there? I looked at the site and still can't tell. Not much of a product if you're left with a brick. To do nearly the same thing you could just run a destructive drive test on the BIOS or a seagate/wd utility floppy.

If it leaves the OS on there and scrubs everything else, that'd be cool. A laptop without an OS would be expensive and troublesome to deal with.

I've used the Norton "Wipe Info" from the Norton utilities and chose the governement wipe when I gave my old pc away. I wiped the whole hard drive. It is supposed to make it impossible to read what was written. I'm no computer guru though, maybe ask in the computer forum.

Do you have any data that you would not want the new owner to have on the PC? 99.99999999999999% of people would not know how to restore data even after a plain jane shift delete, let alone after a format. I would first see if there was ever that confidential of information on the system.

If there was just have the new owner buy a new laptop HD for ~50 to 100 bucks from newegg.com and dispose of the old drive yourself.

Option 1
Use the install CD to do a reinstall
Defrag the hard drive
Give to friend,
This will keep the average person from restoring your data.

Option 2
Take drive out,
Smash drive, toss parts in the ocean
buy new drive
This keeps the NSA from restoring your data

Yes I have confidential information on the laptop, hence the need to scrub it.

I have done many system reinstalls, so they're no big deal.

The computer I am giving away is a 4 month old Toshiba that I paid around $2400.00 for, so I think it's probably worth salvaging!

Thanks though!!

Heard a data-recovery specialist on an open line show state with 100% certainty that with enough time and the tools in his electronics lab, he could gather the data on an HD that was "wiped" by commercial methods. He said the governments have programs to erase data, but not available to the common man.

His advice was to buy a replacement HD and swap them out.

The bottom line is: if someone wants it badly enough, they can do it if you give it to them. Swap the drive out, destroy (by fire) the one with the sensitive data and you're in the clear.

NOOOOO!!!!!!!!!! Unless you have to original install disk for the OS and software. There are two area's of concern. Data such as your files you've created ( you probably removed these already ) and deleted data which can be recovered. Commercial data-recovery and data-wiping programs are very weak. If you are not computer savvy, talk first to someone who is. I recovery data every week for people that didn't think it could be obtained, passwords, deleted files etc... But these are high-end forsensic tools not available to the general public. How much computer knowledge do you have?

You are more thoughtful than I. I took my last two notebooks out back and used them for target practice. It was hella-fun! A buddy of mine asked two days later though if I knew of anyone with a notebook for sale as he needed one for his new business. Felt guilty for not having them cleaned and giving them away. They had patient info on them however and I was nervous about the info surfacing.

Second vote for dban. It wipes the drive then gives you the option of writing null data over the entire drive. You can chose from several algorithms which write random characters to the entire surface for multiple passes, depending on the standard you choose. Depending on the size of the drive this can take a couple of hours, so let it run and grab a frosty adult beverage or something.

This checklist applies to DBAN version 1.

Free.
Fast. Rapid deployment in emergency situations.
Easy. Start the computer with DBAN and press the ENTER key.
Safe. Irrecoverable data destruction. Prevents most forensic data recovery techniques.

Wipe Methods

Quick Erase
Canadian RCMP TSSIT OPS-II Standard Wipe
American DoD 5220-22.M Standard Wipe
Gutmann Wipe
PRNG Stream Wipe

DBAN supports all Microsoft platforms and securely destroys FAT, VFAT, and NTFS filesytems.

MS-DOS, Windows 3.1
Windows 95, Windows 98, Windows ME
Windows NT 3.0, Windows NT 3.1, Windows NT 3.5, Windows NT 4.0
Windows 2000, Windows XP

DBAN supports all unix platforms and securely destroys ReiserFS, EXT, and UFS filesystems.
FreeBSD, NetBSD, OpenBSD
Linux
BeOS
QNX

It is nice of you to give it away. I hope you can resolve your security issues.

If ANYONE has a notebook they don't need, I could really use one for my free-lance writing biz. I just don't have the cash for one right now and it's keeping me from doing some assignments for my local paper. (The pay on the assignments isn't enough to justify buying a laptop on credit). I can get an OS if neccessary.

Seriously, if anyone has an unneeded laptop, I'd give it a good home. The only thing I can promise is to "pay it forward" in the future.

There is a program called Autoclave that we always used for sensative data on machines at work.

i haven't heard aefdisk mentioned. anybody have experience with that? it's what i've always used. i don't know how secure it is.

if the info on there is so important that you're worried about somebody using a high end data retrieval program to get it back, you should physically destroy the drive. i don't know anybody that has ever used a program like that, and i'm pretty darn computer savvy. i think the only people you'd have to worry about would be the NSA, etc.

Dowload the PGP encryption program from the link below. There is a utility that comes with the program that allows you to wipe the disk to the degree with which you feel comfortable. Also, encrypting sensitive data isn't a bad idea. Encrypting particularly sensitive data and then wiping the drive would give an added layer of security.

I just want to have the information erased. I don't wear a tinfoil hat, so I don't have concerns that a government agency will be trying to obtain my information.

I purchased System Mechanic5 Professional (http://www.iolo.com/sm/5pro/indexsm.cfm) , which includes a drive scrubber and will see how it performs.

Thanks for the replies!

I think you are just being silly.

Simple solution: Don't give it to someone you can't trust. :)

Do a clean install anyways, your friend will thank you, since the system will run much quicker than one with lots of useless junk on it (granted, a restore CD sometimes puts junk on it anyways, but that's a different matter).

Steps:
-create a boot disk. Depends on your OS, but it really simple to do.
-reboot your computer, let it boot off of the disk.
-start without CD support (unless you want to wait an extra couple of minutes)
-run "fdisk"
-delete all partitions
-restart, and boot off of the disk
-run "fdisk" again
-create a partition, let it use up the entire drive, and let it set it to default (you could also separate it into multiple logical drives, but that is a bit more complicated, and I want to stay simple)
-restart and boot from disk again
-run "format c:"

If your system came up with a restore disk, go ahead and run it, tell it to do a clean install.

If you don't have a restore disk, and you are using Win9x, you can copy the "Win[ve]" directory from the CD to the HD, and run setup from the HD.

Thanks for the tutorial, but as I said before I've reinstalled many times - a walk in the park for me. BTW doing a restore does not scrub or erase the hard drive.

As for ignoring sensitive confidential information and giving the laptop away only to someone I "trust" - that's a ridiculous comment as you have no idea as to what information I may have had on the laptop, nor what it was primarily used for.

As for being silly, perhaps I am. But since you think ensuring personal or confidential information remains secure is silly, why don't you post your banking/investment information for everyone here. You're naive if you think it's not prudent to keep confidential information confidential.

In any event, the disk was scrubbed with the iolo product and should be sufficiently scrubbed to pass on to my friend.

Too bad I just gave away a Toshiba 320CT 3lb laptop with docking station to my billing clerk, but you can find something decent on ebay for as little as $200 - I actually replaced the 320CT with a Portege 3080CT for only $305 + S&H, which is a PIII 600 3.0lb ultrathin with 128mb/12gb and external DVDROM. Can't pass up deals like that when the thing was $2,400 new 4 years ago and still has enough power to run most business apps. It runs Win 2K Pro just fine. Last fall I bought my kids an iBook 600mhz G3 with DVD/CDRW for $399, as another example...

Go there and do some searching and you can find good deals.

That will not work.

Try it, it won't let you format a drive that is mounted..
