Solutions To Erase Boot Drive From Public Drive


Over the past few days, some drives have reported detecting a bootable floppy disk for erasing government floppies. The DoD 5220.22-M disinfection method is one of the most common disinfection methods used in data destruction software and is still generally considered the industry standard in the United States. Most data cleaning software, including Blancco Drive Eraser, support multiple data cleaning methods, including DoD … March 28, 2019



What Is DoD 5220.22-M Disk Erase?

DoD5220.22-M, also known as the Department of Defense Standard, is a software-based data wiping method that wipes out a hard drive and other storage devices by overwriting existing data. This method of erasing a hard drive can prevent almost all software recovery tools from displaying data and information.

DoD 5220. The 22M erase method was used in 1995 to delete confidential US Department of Defense documents. This method was published by the Department of Defense in the National Industrial Safety Program Instruction Manual, which describes the process of rewriting a hard disk with a series of zeros, ones, and dates in 3 passes.

– Step 1: Overwrite the hard drive with zeros
– Step 2: Overwrite the hard drive with zeros
– Step 3: Overwrite the hard drive with random data

These 3 passes make the DoD layer removal method much more secure than any previous method. Today, DoD 5220.22-M is one of the most common methods of destruction ofdata that prevents the hard drive from being erased before it is given away or disposed of.

DoD 5220.22-M Erase Method

The DoD 5220.22-M data cleansing method is usually implemented as follows:

  • Step 1: write down zero and check the entry.
  • Step 2: write A and check the letter.
  • Step 3: write a random character and check the spelling.

You may also encounter various iterations of DoD 5220.22-M, including DoD 5220.22-M (E), DoD 5220.22-M (ECE), or others. Each will probably use the symbol and its complement (e.g. 1 and 0) and different reference frequencies.

Although less common, there is another modified version of DoD 5220.22-M that writes 97 instead of a random character on the last pass.

Free Software Using DoD 5220.22-M Removal Method

Some freeware programs use the DoD 5220.22-M disinfection standard to remove all information from the hard drive.

Our favorite tool is DBAN , but we also like similar tools, including CBL Data Shredder .

Eraser , Safe Paper Shredder and Freeraser are examples of free paper shredders that offer the ability to clean files based on DoD 5220.22.

What Is SD I / O Error And How To Fix It?


Recently, some users reported having encountered SD I / O errors.

I / O Error (short for I / O Error) means that there is a problem with accessing the hardware. If you get this on media, it means your media is dead or dying, or you have a loose cable, a poor device, or some other hardware issue. An I / O error from the SD card means it is dead.



I tried gparted but it didn’t work. I found the SDFormatter tool for Windows that has been completely removed.

I have an SD card and want to install Debian on it. The dd process takes about 45 minutes, then I terminate it. On my Windows computer, it shows up in the drive list, but it gets an undefined error when formatting or even opening. gparted tells me

  / dev / mmcblk0: unrecognized disk label 



  dd if = 'deb.iso' from = / dev / mmcblk0 bs = 512kdd: Error writing '/ dev / mmcblk0': I / O error0   1 data in0   0 data outputcopy 0 bytes (0B), 10098 s, 0.0 kb / s 

Then I tried

  root @ kali: ~ # lsblk -o NAME, FSTYPE, MOUNTPOINT, SIZE, RONAME F TYPE MOUNTAIN SIZE ROSDA 465.8G 0- sda1 ext4 / 450.1G 0- sda2 1K 0- sda5 Swap [SWAP] 15.7G 0sr0 1024M 0mmcblk0 29.5 g 0 

mmcblk0 is the one I’m having problems with. Last tried

  root @ kali: ~ # mkdosfs -F 32 -v / dev / mmcblk0mkfs.fat 3.0.26 (07.03.2014)/ dev / mmcblk0 has 4 heads and 16 sectors per track,hidden sectors 0x0000;logical sector size 512,Use media descriptor 0xf8 with 61896704 sectors;Drive number 0x80;The file system has 2 32-bit FATs and 32 s Per cluster.The FAT size is 15 105 sectors and 1933 326 clusters.There are 32 reserved areas.Volume ID - 2df52746, no volume description.mkdosfs: Error writing reserved sector 

I have no idea why it doesn’t work.

Root Causes Of Hard Disk I / O Failure

  • Outdated drivers
  • The hard disk is not compatible with the operating system platform.
  • The CD / DVD writer and USB port are defective.
  • A free USB or E-SATA cable.
  • Physically damaged hard drive.

sd i/o error

Most device I / O errors can be corrected by checking no connection, hard disk properties, and so on. There are several solutions to these problems. Before continuing to fix these errors, you must first do the following:

  1. Restart your computer / laptop.
  2. Try to access the disk / device again.
  3. If the problem persists, try accessing the data device / disk on another computer / laptop to ensure that the disk or device is not damaged.
  4. The device I / O error has been resolved and you will no longer receive the error message. You are done. If the problem persists, use the following solutions:
