![]() ![]() When the data is not accessible on any of the drives, may that be HDD, SSD or a Flash Media, it is extremely vital to diagnose the exact reason of the failure to accessing data. Simply retrying to access the data without knowing the issue can lead to further damages to data stored or the drive itself. This may further lead to either compromising the integrity of the data or even losing the data forever! We at 3rd Eye Techno Solutions Pvt Ltd setup the new Damaged Media Data Recovery Labs as well as provide services on case to case basis.Ĭloning and Imaging of these devices is a mundane job now a days due to the ready-made hardware devices available in almost every forensic lab. All the investigator must do, is connect the drives on the appropriate write blocked port, connect a fresh drive on the source port, select an appropriate function from the wizard driven menu of the imaging hardware and wait back till the job is completed!Īlthough, the real investigation work starts after the data is captured as mentioned above, the problem arises in case where due to some or other reasons, the drive is not letting access to the data. is a very regular work in any of the forensic science laboratories across the country. In general, it involves connecting the write blockers to the media device and then reading the whole contents on it bit-by-bit and making either a clone or an image of the data. So, pending any other experiments, I'd call the cheaper neodymium magnets busted it's either the $500-$600 degaussing wand, or nothing.The forensic data recovery from any memory devices like Hard Drive, Solid State Drive, Flash Card, Pen Drive etc. However, according to their own blog, which performed an actual experiment on a live hard drive, this doesn't work at all! Per the comments, this might be because simple magnets don't offer the rapidly oscillating magnetic field that the commercial degaussers do. Looking through the magnet selection, one of the larger neodymium magnets will run you from $5-$20 so that's much more cost effective, if it works. Also they are incredibly hard to get apart once they stuck together. Getting your finger caught between two magnets will cause a serious pinch. The magnets are much stronger than you could imagine. Just be careful to read and heed the warnings about the magnets on K&J's site. They also worked great to erase 3-1/2" floppy disks and some flash memory cards. The neodymium magnets fully erased a hard drive with less then 30 sec of rubbing in circles on both sides of the drives. ![]() I did some experiments on an extra working drive. ![]() I then found a site called K&J Magnetics ( ) which sells super strong neodymium rare earth magnets. I got the idea of using a permanent magnet to erase the drive but I read many postings of people who tried but failed using old speaker magnets. There are some vague forum reports of buying very strong neodymium magnets and using those to degauss the drive by rubbing it on both sides: NSA approved degaussing wands appear to run about $500 - $600. You can also get a bunch of magnets and hope that scrambles enough of your data. For completeness, there's always demagnetizing.
