Frequently asked questions about Acronis Drive Cleanser 6.0
What is the purpose of Acronis Drive Cleanser 6.0?
Acronis Drive Cleanser 6.0 was written specifically to obliterate confidential data from partitions and hard disk drives.
There are algorithms of different complexity and speed offered for data destruction.
Acronis Drive Cleanser 6.0 includes most known national governmental standards for hard disk data destruction, for example the U.S. Standard, DoD 5220.22-M.
Acronis Drive Cleanser 6.0 also includes powerful erasing algorithms developed by authoritative experts in computer data security.
Who does need Acronis Drive Cleanser 6.0?
Acronis Drive Cleanser 6.0 is intended for anyone responsible for data storage (and destruction!) in corporations, financial and government agencies, legal and even small businesses, where confidential documents or data is formed and used. The top users of our software are system engineers and information system administrators, and servers and databases maintainers.
Acronis Drive Cleanser 6.0 will ensure permanent erasure of sensitive data completely eliminating the possibility of erroneous data recovery.
Why is it insufficient to simply delete files containing confidential data?
Any file system registers the file by its name in the File Allocation Table (FAT) of a partition, while the file data itself is stored in the sectors of partition (hard disk) forming a chain. The deletion of files by means of an operating system only deletes the filename from the FAT, while the sectors containing the actual file are considered free. Data may be written to the sectors after the file name deletion from the FAT, but the file data remain intact unless randomly overwritten. Deleting a file name in the FAT does not assure that data will ever be written over that files data sectors on the hard drive.
The Windows operating system, for example, allows users to easily recover deleted file. There are also many popular utilities software products that also serve this purpose.
It is more difficult to recover deleted file in the Linux operating system. Files and data are bound up with the greater complexity in Linux's own file systems such as Ext2, Ext3 and ReiserFS. But even under Linux, file data is still stored in disk sectors even after the deletion.
Both off-the-shelf software, and rather inexpensive, simple hardware device may be used for the recovery of files, data, hard disk controller capabilities and even magnetic microscopy.
Why is it insufficient to format or delete partitions containing files with confidential data?
The formatting of a hard disk partition does not affect the data written to the sectors of a hard disk in any way. Formatting just creates the data storage structure on a disk, this is known as a file system. If you just format a hard disk drive partition, only the names of files registered in the File Allocation Table will be destroyed your confidential data will remain in sectors of the hard disk.
Partitions existing on a disk are described in the Partition Table of the hard disk. Simple deletion of a partition only makes the sectors of that partition to be considered unallocated. Files and data structures of the deleted partition remain intact. It is even easier to recover a deleted partition and all the files on it, than after the formatting.
What are hard disk wiping algorithms based on?
All algorithms for the destruction of data are based on multiple overwrites of data on the hard disk drive sectors, or if from a physical stand point on multiple switching of recording material over the disk surfaces.
Algorithms used in national governmental standards provide for filling each byte of each hard disk sector with ones, random values, or complimentary values to those written during the previous pass. Wiping implies at multiple passes on the hard disk.
For example, the U.S. national standard offers writing of the following:
First pass random values;
Second pass complimentary values to those written during the previous pass;
Third pass random values;
Fourth pass writing verification.
Why the more powerful algorithms, than those offered by national standards necessary?
The adoption of new or updated government standards for wiping data takes much more time than the development of both software and hardware data recovery tools.
Modern computer hardware and electronics are inexpensive, does not require highly qualification personnel, and allows users to recover hard disk data from barely perceptible traces or repeatedly deleted records. While bureaucrats debate new technology and algorithms for data security, individuals and groups will ill intent continue to develop new ways to erroneously recover sensitive data.
Therefore the most powerful algorithms of data destruction in the Acronis Drive Cleanser 6.0 offer up to 99 customized passes on the hard disk.
What is the main advantage of Acronis Drive Cleanser 6.0?
The main advantage of Acronis Drive Cleanser 6.0 is that it offers not only national standard algorithms for data destruction, but also much more powerful wiping algorithms developed by authoritative experts in data security.
Acronis Drive Cleanser 6.0 also allows you to create custom algorithms that will meet and exceed your data security needs and speed requirements.
What operating systems does Acronis Drive Cleanser 6.0 work under?
The answer to this question may be divided into two parts.
1. The installation program on the CD-ROM may be run from Windows. You may run our installation wizard directly from the CD, or create a bootable diskette.
2. If you create a bootable diskette, Acronis Drive Cleanser 6.0 does not require any operating system to work with the disk functions of your computer's BIOS.
What disk sizes does Acronis Drive Cleanser 6.0 support?
As Acronis Drive Cleanser 6.0 does not actually require an operating system, it will work with disks of any size that support the BIOS of your computer.
Will Acronis Drive Cleanser 6.0 work under Windows XP?
YES! The Windows XP operating system works with FAT16, FAT32, NTFS hard disk file systems.
Does Acronis Drive Cleanser 6.0 work with hard disks that have Linux operating system installed?
YES! Acronis Drive Cleanser 6.0 works with the most popular Linux OS file systems like Ext2, Swap, and ReiserFS.
