The first section below describes how to prepare a bootable USB Flash drive (or any USB drive), so that you can boot from it and run HDDErase.exe on any system that will boot from a USB drive. So HDDErase is actually both faster and better as a 'security wipe' program than other types which merely erase the normally accessible sectors of a disk. HDDErase also wipes hidden sectors and also those sectors marked as 'bad' and which cannot be overwritten by normal wipe programs - these sectors contain old user data which could be accessed by an advanced engineer or hacker. You can save hours of time when erasing a hard drive. This is MUCH faster as the erase utility does not have to write GBs of data to the drive. However, if you use CMRR Secure Erase ( HDDErase), it sends a special command to the hard disk which tells it to erase itself. Many 'Erase' programs work by writing all 00's to all normal sectors on the drive. However, you must reboot your system to a different operating system first as Windows normally will not allow you to overwrite it's system files whilst it is running. You can use a special 'Erase' utility to wipe your entire hard disk. remove Windows, Linux, boot code, Master Boot Record, partition tables, pictures, games, music, browser password files, financial spreadsheets - everything) remains. Just re-installing the Operating System using the original manufacturers CD/DVD will not remove your personal data! So first you should wipe all the data from your hard disk so that no data at all (i.e. If you want to sell or give away or dispose of your system you should first wipe the data from the disk.
