Slightly OT : Disk wiping?
Hi,
As my hard drive has to go back, has anyone got any recommendations for any good, free, disk wiping software? I don't want anyone seeing some of the data that I've got. Thanks, Grendel. |

Except you could end up sending it back with a different fault to the one you reported to get the RMA. SteveH |

This is the best one to use. It has a number of wipe methods you can use. Depending on the size of your drive it can take a long time too. The Guttman wipe method overwrites the drive 35 times and takes a very long time. If you just want to write zeros to the drive (low level format) it is fairly quick. http://dban.sourceforge.net/ |

Actually, there are few ways of truly wiping data:
o When a HD head records data it does so by following a servo track ---- following the track results in data being recorded to the side o Data is recorded as a probability distribution around the servo track ---- it is admittedly a very tight distribution, but it is one none the less o An edge of layers of dated data remain distant from the servo track ---- over-wiping in theory reduces that incrementally The problem is in theory isn't necessarily in practice: o Mil spec wiping requires as I recall 4 overwrites ---- so diminishing such edge data to an unrecoverable level o Overwriting also requires attention to the pattern used ---- otherwise it is possible to predict what was there ---- reverse-ECC, signal level & other tricks counters that Remember a HD is an analog device - not digital - in recording. Yes the signal is 1s & 0s, but analog techniques can interpret what data was there before based on its particular value re 0.83 v 0.85 etc. The reality comes down to security level required: o NSA can pull your platters & use lots of tricks to get data back o For basic financial, email etc data a decent program will suffice :-) The most critical military/gov't uses a different method: o Either a belt sander to remove the physical magnetic media ---- platters once aluminium are now glass in most instances o Alternatively they just melt them down ---- probably more economic in terms of labour Wiping data is an important consideration: o MS-IE / XP regularly store auto-complete info for passwords ---- auto-complete on email address, get from ISP/Outlook settings o Take someone's HD and you can access all financial info ---- transferring funds, pensions, bank contents ---- expenditure on credit cards, debit cards At present identity theft is easier via your dustbin in the street, but a stolen laptop owned by a financial adviser is a potential risk. USA tends to have more problem with advisers bunking with money, which overshadows that done more legally by CEOs & Wall Street :-) For critical applications it is worth keeping a spare original HD, a fully as-delivered-drive-O/S ready to go. That way if a laptop or PC has to be sent for repair that can be enclosed with it, and also very useful if your machine keels over (particularly if a laptop). It is then just a matter of re-installing kep apps, your ISP settings & your data. -- Dorothy Bradbury |
