Come on chaps don't appear so shocked its not like we never knew that.
I've read a few other articles about card fraud due to the previous owners of hard drives not securely wiping their data...if you ask me, the people who don't wipe their hard drives well they deserve everything they get for being so careless...
Who appeared shocked in any of them replies?
Rubish. It is easy to do yourself, so long as you have a clue:If you want your data wiped properly, use an expert, (Disklabs, 1st Computer Traders Ltd or PC Association member).
- Boot from a knoppix disc
- Open a command console as root.
- dd if=/dev/urandom of=/dev/hda
- mkfs.vfat /dev/hda
Filling the disc with random will take about an hour, or more for larger discs. If you are paranoid you can do step 3 several times. If you have more than one physical drive, repeat step 3 for hdb, hdc etc, replacing hda with sda etc if you have scsi drives. I would defy anyone short of the NSA to recover anything usefull from a disc that has been subjected to that treatment.
nice tips that
use GNU shred -alter n if you want to be sure. remove -z if you don't want to follow the random treatment with zero-fillingCode:shred -v -z -n3 /dev/harddiskdevice
Useful reminder though...
Yes it is easy to wipe data yourself, BUT you need to know 100% what you're doing. Especially if your data may be sensitive or you don't want it falling in to the wrong hands.
If you don't understand Linux it can be pretty easy to stuff it up or not wipe the disk properly. I've seen cases where "experienced" and "knowledgeable" IT *Managers* have screwed up the wiping of old workstations and gave them away still containing sensitive corporate documents and email, even with bootable operating systems with recoverable and crackable admin passwords on the disk - just because they were told it was easy and tried it themselves.
There are much simpler DIY methods of wiping than using a Knoppix (Bootable Linux CD) disk. DBAN, dban.sourceforge.net, is another free one which also does a good job. It depends upon your disk / computer speed but it would take 1-2 hours to do a simple DIY wiping pass on an average workstation.
If you really want your data wiped properly and securely you need to also verify the wiping i.e. by writing 00h across the disk on the last pass and then searching the disk to make sure that nothing other 00h appears on the disk.
Professional data wiping companies will perform all the required steps using documented industry standard secure procedures and produce a report and a certificate of data destruction for each workstation/hard disk. You can even have the hard disk physically destroyed afterwards for the uber paranoid.
