UltraDefrag is an open source disk defragmenter for Windows NT 4.0 and later operating systems. It is very fast, because the defragmenting is done by kernel-mode driver. UltraDefrag makes use of the same defragmenting API used by many other windows defrag utilities, both open and closed source. However, UltraDefrag has many features that makes it unique. Firstly it has a kernel mode driver that does most of the work, secondly is the ability to run the application at boot up time in a manner similar to chkdsk. This allows for faster defragmentation time and the ability to defragment all files including system files. It can also defrag single file or multiple directory and can generate a list of all fragmented files. The program is available for both 32bit and 64bit version of Windows running on both AMD and Intel based processor. There are three interface available: Graphical, Console and Native. The UltraDefrag Micro Edition is a special package for advanced users who prefers extreme stability and power.


This edition is a little bit faster, much stable (its driver contains just most important parts). It has console interface to speed up defragmentation process. Boot-time feature is available too. The Micro Edition saves reports in plain text format.

Active SMART is an award winning hard disk status analyzer and failure prediction software for your hard drive. It uses S.M.A.R.T. (Self-Monitoring, Analysis and Reporting Technology) to monitor the health status of Hard Disk Drives (HDD), prevents data loss and predicts possible drive fail using special algorithms. Active SMART has several monitoring modes and can be used for personal use as well as for large computer systems. Various local and remote monitoring modes and alerting options are available. Active SMART allows every HDD in the system to be monitored for faults and potential failure 24 hours for a day for things that may lead to a crash. If a fault is detected, you are notified with various local alerting options. Also remote notifications via e-mail or network messenger are available. With Active SMART you have full information about S.M.A.R.T. status of the hard disk, general information about the drive, special information about drive's features and manufacturing information.

You can also use this tool to work with your documents: to find and delete old back-up files and duplicates based on various criteria you can select. The program is easy to operate for first time users, yet has a powerful mix of settings for advanced tweakers. The disk cleaning process can be launched automatically by command-line, reducing your supervision to save you time. Works in any 32-bit version of Microsoft® Windows® operating system (2000/XP/2003/Vista/7).

SBMAV Disk cleaner features:
• Search and delete temporary files and folders. The disk cleanup function performs cleaning only of standard folders of temporary files. But hard drives contain much more unnecessary information, which this function can detect and delete.
• Its unique self-learning system (MAVQSM™) performs a disk scan in seconds. To prevent inexperienced users from losing important data, a security system is embedded in the software.

Hard Drive Inspector is a powerful, effective and easy-to-use program that monitors hard drive health. The value of information stored on an average computer hard drive often exceeds the value of the computer itself. But a hard drive is one of the most unreliable internal computer devices. When it crashes (which happens quite frequently), the stored information will be lost fully or partially. Subsequent information recovery is either not possible at all, or constitutes a very sophisticated and expensive procedure that can be performed only by specialists.
Modern hard drives support S.M.A.R.T. (Self-Monitoring, Analysis, and Reporting Technology) that was specially developed to detect upcoming disk failures. Using this technology Hard Drive Inspector can monitor the current state of various life-critical parameters describing a disk's reliability and performance.

Hard Drive Inspector analyzes this data and warns the user if the parameters indicate a critical reduction of disk reliability. Timely alerts make it possible to copy the data and replace an unreliable disk, thus preventing information loss.

Its goal is to find, test, diagnose and repair disk drive problems, report and display SSD and HDD health, performance degradations and failures. Hard Disk Sentinel gives complete textual description, tips and displays/reports the most comprehensive information about the hard disks and solid state disks inside the computer or in external enclosures (USB / e-SATA). Many different alerts and report options are available to ensure maximum safety of your valuable data.
The software monitors hard disk drive / HDD status, including health, temperature and all S.M.A.R.T. (Self-Monitoring, Analysis and Reporting Technology, built in most hard disks and solid state disks today) values for each disks. Also it measures the disk transfer speed in real time which can be used as a benchmark or to detect possible hard disk failures, performance degradations.


HDSentinel is the perfect data protection solution: it can be effectively used to prevent HDD failure and SSD / HDD data loss because it has the most sensitive disk health rating system which is extremely sensitive to disk problems. This way even a small HDD problem can't be missed.
