The wrong way leaves traces of data on the hard drive, making it possible to retrieve all the data either in its original format or in a format that can be used restore the original. Learning how to reset your computer to factory default settings is essential, especially when computers are an integral part of our daily lives. Whether you pass on your computer to a new owner or want a fresh start, these instructions will guide you through data cleansing.
To successfully process each material that devices contain, it’s important to know how to take apart a computer. The effectiveness that this method of erasure achieves far exceeds that of DC erasure . If you’re a handy person and want to know how to dispose of hard drives or if you’re wondering, “how do you remove a hard drive?
Securis’ Statistics
Wiping your computer hardware doesn’t require too much technical knowledge. But if you need some guidance, follow the instructions below to wipe your hard drive on Windows and macOS computers.
You might check with accounting to ensure that they don’t include data that might be requested by the IRS/. For example you usually need to keep financials for 7 years – if you get audited, all you need to do if buy/rent a new drive to recover the data. Our old tape drives have failed and we not using tapes for backup anymore. We still have a stack of DLT tapes with backups which may contain sensitive information like credit card numbers, social security numbers, etc. My understanding is that they’re not strong enough unless the platter is physically removed from the disk drive.
How-to destroy sensitive data on floppies?
This is useful information (+1), but it seems like it doesn’t directly answer this question since the manufacturer actually is in a position to replace the entire logic board. If you’re particularly paranoid, buy a new drive and stash the old one in a safe until the data is no longer a security problem. One thing to consider is that using a super-strong magnet to alter the data on the drive might conceivably cause the drive manufacturer to void your warranty. If they get your HDD that “just died!” and notice that it’s been magnetically savaged, they might claim it’s all your fault and charge you for the replacement. Also, a proper degaussing will definitely erase the drive’s firmware as well, which could be problematic.. Just be careful to read and heed the warnings about the magnets on K&J’s site. The magnets are much stronger than you could imagine.
Degaussing for data sanitization is:

Certainly seems likely that the eraser program deleted everything off the disk, including the operating system. It’s unfortunate that you do not have the re-installation media. It’s just that the new owner will have to get an operating system going on it, and find any necessary drivers. This leaves the drive more empty than when it was shipped from the factory, but the manufacturer’s low-level drive info is still there and the drive is formattable and usable. The proper way is to overwrite each and every sector on the drive with random data. Once is enough for all but perhaps an intelligence agency to recover BUT there is a defense department method that uses rewriting seven times with different data that will ensure even the NSA won’t be able to do it.
