![]() These days, destruction is frowned upon due to risks of pollution of the planet and increased costs.SOURCE: 2000 VW jetta VR6 windshield wipers wont workįirst try the fues box see if you have a blown fues, next if you put your wipers on can you hear the motor running for them? if you can the linkage has poped off from the motor, its a bit awkward to get it back on and no gaurentee that it will saty on, you might have to replace linkage, or, it might be the cogs on the actual wiper arms have splayed and are now smooth so they dont grip to move, you can take them off by the nut on the arm, get a can (coke can or simular) cut a rectangle out of it the hight and width if the cog, rap it round the cog, (make sure it does not overlap on the ends) and force the arm back into place and then do the nut up, this is just a short quick fix if that is the case you will have to replace the motor, also you can check the relay to the motor in the fues box, give it a tap a couple of times it might work again if not replace it. Ensure that the heel is positioned within 0.2 inches (about 5 mm) of the park line. Step 4: Check the park line of the blade. Step 3: Then allow the wiper blade to touch the glass by releasing it, thereby adjusting the tension. Specifically excluded are practices like bending, cutting, or punching/shooting holes in devices, which are dangerous and might not prevent data retrieval.ĭestruction includes methods that completely destroy physical media, such as shredding devices to such a small size that they are impossible to reconstruct. Step 2: After turning on your wipers, select the park position and lift either blade by hand. Purging could include overwriting procedures, but could also mean options like secure erase or cryptographic erase, as well as destructive techniques that effectively prevent access to data. “Section 5 Summary of Sanitization Methods” defines three steps: clearĬlearing data involves an overwriting process, by which target data is replaced with non-sensitive data (junk data). ![]() DoD 5220.22-M has not been updated in recent times and does not apply to more modern technologies like SSDs. NIST 800-88 has become the “go-to” media sanitization standard when compared to another well-known standard, Department of Defense (DoD) 5220.22-M. However, if you consider stronger standards, you need to look at options described in NIST 800-88 Rev 1. ![]() If you want something simple and not DoD or industry-approved, these tools/utilities could do a basic job: a) Shred.Į) Boot from a rescue disk and write to the physical device or partition using dd: The main question is what secure disk clean really is for your organisation and you. RJ and Jamie already gave you some options to consider. UPDATED/ADDED: Please see the very relevant post below from Jamie Bainbridge of Red Hat It's probably a good idea to unmount it first so that no one is using it, including a possible cron.įor the sake of discussion, let's say the drive you wish to wipe is on sdb, you could do this: ~ ] # sudo wipefs -all -force /dev/sdb* You can also type man wipefs to see Red Hat's man page.īefore proceeding, please know that you need to verify beyond any shadow of a doubt the actual file system you wish to run wipefs against. Please do see the manual "man" page for the wipefs command. However, for you, consider "scrub" above. HTGWA: Create a RAID array in Linux with mdadm. Then if you want to use the device for something else, wipe it with wipefs: wipefs -a /dev/nvme0n1 See the kernel documentation for bcache for more detail and usage examples. At this point, you should have back all the drives that were part of the array and can do other things with them. ![]() Zero the superblock on all the drives: sudo mdadm -zero-superblock /dev/sda1 /dev/sdb1. Stop the RAID volume: sudo mdadm -stop /dev/md0. To answer your immediate question of securely wiping a partition, please see this Red Hat link discussing the use of "scrub" DISCLAIMER SEE Jamie Bainbridge's post below.įor generic non-secure wiping of a partition, wipefs would be an option. To avoid the initialization when making the filesystem, you can omit the -E option entirely. Wipe the ext4 filesystem: sudo wipefs -all -force /dev/md0. It's worth double if not triple-checking this just to make sure. I'll mention it twice here, please make absolutely certain you really target the proper disk to be scrubbed.
