This device can be used to wipe a drive however if you read the bold note at the bottom of the product description and I quote, "Please note: Hard drives are NOT reusable once degaussed." Most likely due to the fact that it scrambles the low level formatting (track and sector markings) of the drive. Once the track and sector markings are scrambled the drive is rendered pretty much useless. Unless you send it back to the manufacturer to be low level formatted again. Taken from same site, "Magnetic media products that have factory pre-recorded magnetic servo patterns should not be degaussed. Degaussing would erase the factory written magnetic servo signals and leave the media unusable." in other words hard drives. I am not aware of any hardware method to wipe a drive and leave it in 100% usable condition. -----Original Message----- From: full-disclosure-admin () lists netsys com [mailto:full-disclosure-admin () lists netsys com] On Behalf Of Michael Cecil Sent: Saturday, April 03, 2004 4:35 PM To: full-disclosure () lists netsys com Subject: Re: [Full-disclosure] erase with magnet At 03:18 PM 4/3/2004, Michal Zalewski said:
Some folks made quite brave claims about inability to degauss a disk, one guy even claiming the field needed to accomplish this could possibly kill the operator, but this seems to be quite silly considering there is a number of hardware degaussers for hard drives readily available on the market, some of them certified and used by fairly reputable organizations:
There are? Show us one.
