Lazesoft Wiping Disk/Drives Algorithms

Wiping Algorithms of Lazesoft Recovery Suite

How does wiping perform

Introduction

“Deletion is not secure. When a file is deleted, only the file name and file entry is marked deleted. This mark tells the system the file has been deleted and the space is free’. In fact the data of the file remains on the disk. It may remain on the hard drive until the ‘free space’ is overwritten. Formatting is also not secure. When a partition is formatted, only the file file allocation table, bitmap, boot sectors, and some file system reserved area are overwritten. The file directory table and file data maybe still remains on the disk. The files deleted or in the formatted partition can be recovered by data recovery software.” This is the reason, why the Wipe feature is required.

About the wipe algorithms

All the wipe algorithms performs the overwriting of all the sectors in the selected partition or disk, including the data area and free space.

 

wipe_disk_algorithms

There are several algorithms to wipe:
“Erases with one-pass zeros” – all the sectors are overwritten once with “0”;
“Erases with one-pass random characters” – all the sectors are overwritten once with random characters;
“DOD 3 passes” – all the sectors are overwritten with 0’s, then 1’s and then once with random characters.

 

 

Fix the error 0x00000024

I have a Dell Laptop which is running ATI graphics with Intel processor and 4GB RAM. When I am trying to reboot the computer as usual this morning, the screen will become black and then I will get the following error that says:

Choose WinPE version for Lazesoft boot disk

How do I choose the “Windows version of the target computer” on the home page of Lazesoft Media Builder?

lazesoft media builder select target WinPE boot disk version

lazesoft media builder select target WinPE boot disk version

  • If you choose “DO NOT Specify the Windows version of the target computer”, the program selects the WinPE version from the Windows version which you are running.

 

  • If your Windows computer is 64 bit, we recommend you select the target Windows version, Windows 8.1 64 bit, on the home page of Lazesoft Media Builder.

 

  • If your Windows computer is 32 bit, we recommend you select target Windows version, as Windows 8.1 32 bit, on the home page of Lazesoft Media Builder.

 

  • Windows 8.1 WinPE disk has better hardware compatibility than the Windows 8/7/Vista WinPE disk.

 

  • The 64 bit boot disk performs better than 32 bit boot disk. But, for UEFI boot mode:
  • The 32 bit boot disk only works on 32 bit UEFI boot model computer.
  • The 64 bit boot disk only works on 64 bit UEFI boot model computer.

 

When do I need to use the 32 or 64 bit boot disk?

 

  • If your target computer uses the MBR boot mode, you can use the 32 bit boot disk for both 32 bit and 64 bit computers.

 

  • If your target computer uses the UEFI boot mode, you must choose the 32 bit boot disk for a  32 bit computer.

 

  • You can only use 64 bit boot disk on a 64 bit computer.

 

What if I get the error, “Secure BOOT Failure: a proper digital signature was not found”?

 

If you get the “BOOT Failure: a proper digital signature was not found” error message, please disable the “secure boot” feature in the bios.

 

Follow these steps to turn off the “secure boot” feature in the bios.

  • Power up your computer and press the DELETE key from keyboard during the initial boot     processing.
  • While you are in the motherboard’s UEFI firmware settings, click/tap on “secure boot” menu, select Secure Boot option and press Enter to disable it.
  • Click on the Exit menu > Save Changes and Exit
