Disk Checker is a full-featured disk diagnostics and repairs tool with backup ability. The program runs under Windows 95/98/ME/NT/2000/XP.

Disk Checker includes two separate methods of disk checking: using file-access or direct access to disk surface. The direct access method is much faster and is perfect for large number of small files.

Disk Checker can report defective sectors numbers as well as the file name they belong to. Removable (floppy, ZIP, ORB, JAZZ, etc), hard and CD-ROM disks are supported when using direct access method (you must have administrator rights to perform hard drive checking under Windows NT/2000/XP).

For above cases as well as for remote disks, RAM disks and network drives you can also use the file-access method. You can use this program for backup purposes as well. Disk Checker can create disk images compatible with disk image files produced by other disk copy utilities (Diskcopy, WinImage, DiskDupe, etc).

Disk image is a file that contains all the disk data, such as boot sector, files and folders structure.

It is possible to read and write disk images and format disk. Command line, logging and dedicated item in Windows shell context menu are supported.

CompuSec PC Security Suite description
CompuSec PC Security Suite is a security software designed to protect desktops and notebooks CompuSec is a security software designed to protect desktops and notebooks. It uses pre-boot authentication, single-sign-on for windows Logon, full hard disk encryption, encryption of floppy diskettes and other removable media.
This software is a full version without any limitations.
It is not a demo or trial version.

Pre-boot Access Control in CompuSec requires you to enter your userID and password before the system will boot up.
Once authentication is completed, CompuSec will automatically log you into the windows environment and provide a screen saver lock as well.

CompuSec PC Security Suite is a security software that helps you protect your PC.

Full Hard Disk Encryption keeps your data secret. The encryption uses AES as the standard algorithm. The intelligent program uses ensures fast encryption speeds that will minimize any effect on your work.

Encryption of Floppy Disk and other removable media allows users to secure their data when transferring files between their CompuSec protected PCs.
This feature will ensure that all files are encrypted and only accessible by authorized users.

CompuSec is the entry-level version from CE-Infosys. The high-end model features e-Identity (a secured electronic identity via a smart card or USB token) that will complement your password and store your digital certificates, providing strong two-factor authentication and access control. CompuSec with e-Identity also features file and folder encryption for file servers or local drives, plus IP encryption. CompuSec (freeware) can be upgraded at any time.

Here are some key features of "CompuSec PC Security Suite":

· Pre boot access control
· Encryption for Hard disk using fast AES algorithm and in hibernation mode
· Encryption for CD / DVD for secure publishing and sharing of CD data using CDCrypt
· Encryption for Diskettes and Removable Media Devices such as ZIP drives, USB thumb drives or Memory sticks

DCPP description
DCPP offers AES 256 bit, full disk encryption and pre-boot authentication DriveCrypt Plus Pack (DCPP) is a Full disk encryption application package which encrypts the operating system, and allows pre-boot authentication. The user can enter a password on computer start up, before the operating system boots up.

DriveCrypt Plus Pack provides true real-time "on the fly" 256-bit disk encryption. Providing advanced FDE (Full disk encryption) as opposed to VDE (Virtual disk encryption) or "container" encryption, DCPP is an important evolutionary step in the field of transparent data protection.

DCPP allows you to secure your disk(s) (including removable media) with a powerful and proven encryption algorithm (AES-256) at the sector level, ensuring that only authorized users may access it. The encryption algorithm used by DCPP is a trusted, validated algorithm chosen by the National Institute of Standards and Technology (NIST) and stated to be the cryptographic standard for years to come. AES-256 is a FIPS-approved symmetric encryption algorithm that may be used by U.S. Government organizations (and others) to protect sensitive information.

DCPP is automatic and completely transparent to the user. Not only does this decrease user involvement and training requirements, but also it creates the foundation for enforceable security. The careful integration of boot protection and automatic encryption provides a high degree of security with minimal impact on users.

Boot protection prevents subversion of the operating system (via floppy boot-up, for example) or the introduction of rogue programs while sector by sector encryption makes it impossible to copy individual files for brute force attacks. DCPP safeguards the operating system and the important system files (which often contain clues to passwords for Windows).

DCPP is the fastest and most feature-rich real-time encryption system available, Special care has been taken to render all cryptographic parts as invisible & transparent as possible.

Pre-Boot Authentication
The user is authenticated by means of pre-boot authentication (PBA) before the system is started and therefore before the operating system is booted. This kind of authentication cannot be manipulated, PBA therefore guarantees maximum security.

Neither keys nor passwords are stored on the PCs hard disk. All of the information required to boot the operating system is derived from the password. This makes the use of hard disk tools for analysing the hard disk completely ineffective. PBA in provided by a system call BootAuth and is a fully graphical login screen.

Full Disk Encryption
Automatic & transparent Full Disk Encryption (FDE) offers several key advantages relative to file encryption. FDE secures the system and temp files that often contain sensitive data but are missed by file encryption. Even removing the drive itself does not give access to any file or directory structure.

FDE is performed sector by sector without creating temp or backup files: As a result, large files will decrypt without delay whereas file encryption is normally much slower. FDE also avoids such time consuming tasks as secure deletes of temp files or work files in clear text, and obviates the need to do a full delete on disks to be discarded.

Here are some key features of "DCPP":

· Boot protection
· Pre-Boot authentication: Login before starting the operating system
· Multiple OS boot support (Microsoft)
· Invisible operating system (allows hiding the entire operating system
· Full or partial hard disk encryption
· Sector level protection
· Complete "power off" protection i.e. unauthorised users are prohibited from starting up the PC
· AES 256 bit encryption
· No size limitation for encrypted disks
· Manages an unlimited amount of encrypted disks simultaneously.
· Allows steganography to hide data into pictures
· Trojan and keyboard sniffer protection preventing passwords from being sniffed / captured (red screen modus).
· Anti dictionary and brute-force attack mechanisms (due to the nature of DCPP, it is the most difficult system to attack compared to anything else available.)
· Encrypts almost any kind of media (hard disks, floppy disks, ZIP, JAZ, etc...)
· Administrator /user specific rights
· USB-Token authentication at pre-boot level (Aladdin R2 and Rainbow USB-Token)
· Facility to validate the integrity of the encryption method.
· Recovery disk for "disaster recovery"
· Easy to install, deploy and use.
· Completely transparent to the user
· Minimal administration and user training.

DriveCrypt Plus Pack (DCPP) is a Full disk encryption software package which encrypts the operating system, and allows pre-boot authentication. The user can enter a password on computer start up, before the operating system boots up. DCPP is the only software on the market abel to hide the entire operating system inside another operating system. This is especially usefull if you are forced to reveal the password to an attacker. In this case he will only see prelared data.
