Fastest software to wipe HDD

Taking into consideration a "normal" user, that probably has more or less 500GB HDD SATA2, which would be the fastest way to wipe the HDD ?

* HDD Wipe Tool
* Boot and Nuke
* Secure Erase Utility (not updated anymore I think)
* Other suggestions ?

I've never wiped a 500gb HD, so in your professional opinion/experience, how much would it take to finish ?

Greetings,

The hardware will play a bigger role in speed than the software, and at some point you'll be IO bound by the disk.

If you really must wipe it very quickly, a hardware imaging/wiping solution will probably be your best route.

You will also need to decide if a single wipe is fine, or if you require 327 wipes +/- 2 depending the phase of tne moon

The software on an industrial chipper/shredder set on fine seems to work well.

Insert hard drive in kitchen oven.

Turn kitchen oven to self clean mode.

Return in 1 hour.

Drive size does not matter. As a matter of fact, this solution can do parallel processes, solely depending on space and sufficient ventilation within the oven.

Some 'blenders' depending on the drive casing, can do the same in a fraction of the time, but can only process 1 drive at a time.

. . . Oh . . . Did you actually wanted to use the drive after wiping?

My current software wiping solution will fill a 500GB Seagate 7200.12 drive with 0x00 in less than 90 minutes. That's on the lastest generation of drives of course, so for a slower drive your mileage will vary.

Ok, what IS your current software wiping solution?

Man I hate to think what YOUR oven smells like…..

Since I have now had more than one email on this, I'll elaborate further.

As I have indicated in other posts here, I use a modified version of linux dd to write 0x00 to the entire addressable space of the hard drive. I have been keeping a mental note of the speeds over the years, and as the hard drives get faster, so do the wiping speeds. If you look at for example Tom's Hardware HDD speed charts, you'll get an idea of what kind of speeds you should be seeing during a wipe process. http//www.tomshardware.com/charts/2009-3.5-desktop-hard-drive-charts/h2benchw-3.12-Avg-Write-Throughput,1013.html I've been seeing wipe rates of 90 - 98% of the speeds posted on Toms for the drives on the list that I have personally used. I haven't used a large enough statistical sample to authoritatively say how fast the wipe would be under all situations.

The specific implementation is unfortunately in limited distribution as determined by the author (not me) which is why I didn't bother mentioning it, but if you're good with linux you should be able to make something yourself. I have tested and validated the methodology more times than I care to recall.

I am aware of the arguments about wiping solutions and HDD sectors that aren't available because they are in a GList or PList, but I'm using this specifically to prepare drives for lab or field usage so I don't have to counter some kind of anti-forensics data hiding technique or extreme hard drive failure issue because the drives are under my control the whole time.

The fastest orthodox way would probably be anything based on the ATA secure erase – you have no external bandwidth at all. Anything that involves sending zeroes over the ATA interface will have to cope with both the HDU-to-disk bottleneck, and the computer-to-HDU bottleneck.

(I count microwave ovens and degaussers as unorthodox.)

* Secure Erase Utility (not updated anymore I think)

It just sends a standard command block to the drive. What do you think needs updating?

I just wiped a 120GB 2.5" SATA drive (7200 RPM) last night using a USB port and killdisk in 128 minutes. Probably not the fastest way but this was my personal laptop that I'm getting ready to sell. A FireWire would probably be much faster but my device (don't remember what brand it is now) doesn't have a FW port. My write-blocker is a Wiebetech Ultradock and does not have an option to allow for writes to the HD.

For 3.5" SATA drives my new machine has removable external drive bays that should be much faster but I haven't tried it yet.
