Free Undelete Utility from OfficeRecovery

FreeUndelete restores deleted files, including those removed from Windows Recycle Bin. In case of accidental removal of files on a NTFS (default for Windows Vista, XP, 2000 and NT), FAT32 or FAT16 file systems this is the utility to help.

Supported file systems: NTFS, FAT32 and FAT16

The recovered files are saved into a new location to prevent overwriting the deleted files on the original media.

FreeUndelete is free for personal use. There is no charge, direct or hidden, to download and use a fully functional copy of the program. The program does not install any spyware or adware along with it. It does not populate user’s desktop with pop-up ads or forcefully subscribe user to mailing lists.



A deleted file is essentially an area on disk designated as free and ready to accept data (such as contents of some other file). Luckily, unless the area has already been overwritten, it still holds the contents of the deleted file. Due to this fact it is possible to undelete files.

This fact also dictates the following procedure for using FreeUndelete:

  1. Stop any activity on the disk you are going to undelete files from! Remember that writing to that disk can damage the contents of the deleted files. Examples of disastrous activity include: copying files to the disk, installing programs there or running programs that use the disk as their swap media.
  2. Download and install FreeUndelete. Whenever possible, save the setup executable and install the program to a disk that does not hold files you need to undelete.
  3. Run and use FreeUndelete.
Tip: It is common that the only drive user has is C: and this is also the drive from where files need to be undeleted. In that case a good solution is using a USB flash drive as FreeUndelete download and install destination.

ADRC Data Recovery Software Tools

ADRC Data Recovery Software Tools contains a software suite of data various recovery tools that supports a wide variety of drives and file systems.

The software incorporates extremely simple GUI with novice users in mind. The software zooms in to do only critical recovery functions with minimum complexity so one could recover the data easily. It gives you full control to undelete files, disk image back up, restore a backup image, copy files from hard disk with bad sectors, disk cloning, backup, edit and restore your boot parameters.

Features:

1. ADRC Data Recovery Tools - Undelete

When a file is deleted from the data media, the space that the file used to reside is marked as available or the file in question is marked "deleted". For as long as the space has not been overwritten, the data can be retrieved.

ADRC Data Recovery Tools - Undelete helps you to recover lost and deleted data from hard drives, floppy disks, basic or dynamic volumes, compressed or fragmented files. Besides hard disk drives, it also supports removable devices such as compact flash, Smart Media, Iomega Zip drives, USB drives etc…

The file recovery tool allows recovery of accidental deletion of files. It works on drives formatted in FAT12, FAT16, FAT32 and NTFS file-systems. It works under all windows family operating systems such as Windows 95, Windows 98, Windows ME, Windows NT, Windows 2000, Windows 2003 Server and Windows XP.

You could undelete the files even after you have cleared the recycle bin.

2. ADRC Data Recovery Tools - Copy Files

This is not a normal kind of copy function. The Copy Files tool actually recovers files from disks with physical damage such propagation of bad sectors on disk. Normal windows copy will result in system being "halt" or "hang" (the infamous CRC IO errors). In this situation, Copy Files tool could come to your rescue handy.

The program will attempt to recover every readable bits of a file and put the bits together to salvage your data. It is hopeful that in the worst case scenario, most parts of files can still be extracted even some parts are gone.

To reduce the number of tedious retries, whenever a bad sector is encountered, the program will intelligently search the neighboring sectors to determine the extent of bad blocks and mathematically calculate the number of retires needed.

It also features the "Copy Sub Folders" option which scans through the entire directory and attempts to copy everything you need.

3. ADRC Data Recovery Tools - Raw Copy

Raw Copy transfers the binary raw image from one drive directly to another. It is rather similar to the infamous "Ghost" function. You could perform a disk clone backup (or if your disk is slightly faulty) and do not want perform a file by file copy. This is really ideal if you do not want to re-install the operating system. As the transfer is done in true low level binary, you could do this for drives with an unknown file system to be cloned such as game machines, Mac disk etc. With some built in recovery features, the program will try to recover data even if it is on bad sectors to ensure all or maximum data is restored from the drive.

This is a very powerful function and must be used with care. As it is a binary dump, the original data on the target drive is no longer recoverable upon completion of process.

4. ADRC Data Recovery Tools - Image Backup / Restore

Image Backup / Restore create and write disk image files to and from hard drives and any removable media. In just one click, it performs wholesome backup and restoration of the entire drive. A common application is to create a floppy image for transfer across internet and then downloaded the image to be written back to floppy again. One can also backup a disk image for safe keeping. It is an ideal way to backup all your operating system, data and program files.

5. ADRC Data Recovery Tools - Boot Builder

The primary function of Boot builder is to allow you to import or export the boot sector of a drive (either FAT or NTFS boot sector type). In case the boot sector is damaged due to virus or system corruption, one can easily import it back. You can even custom make your own boot sector from scratch (if you know the standard parameters) to rescue a corrupted disk.

Software is absolutely free and does not require installation.

What is a USB Flash Drive?

What is a Flash Drive?

Equipped with a NAND-type flash memory and integrated with a USB 1.1 or 2.0 interface, a flash drive is a removable, compact and non-volatile data storage device that acts like a portable hard disk. However unlike the size of the latter, a flash drive is usually no longer than a cigarette lighter and only weighs half an ounce.

MECHANICS

Encased in a robust plastic casing, the flash drive contains a small printed circuit that connects to an embedded flash memory and a USB connector. This USB connector often protruded out of its casing to allow the user to plug the drive into the computer’s USB port. For safety purposes, a plastic cap is usually designed to cover and protect the USB connector.

COMPONENTS



1

USB connector

2

USB mass storage controller device

3

Test points

4

Flash memory chip

5

Crystal oscillator

6

LED

7

Write-protect switch (Optional)

8

Space for second flash memory chip

HOW DOES IT WORK?

When a flash drive is plugged into a computer’s USB port, the system’s plug and play capability detects the new hardware and displays a new logical drive in the My Computer workspace. Users can then access the drive by double clicking on the drive icon and simply drag any files across for transmission instantly.

USING THE DRIVE

The flash drive does not require an external power supply. Essentially, it runs off the small power supplied by the USB connection and is compatible with any computer that supports the Universal Serial Bus capability. New USB Flash Drives now support transfer rates up to 480 Mbits/s and storage capacity up to several GB (I recently purchased 32 GB thumb drive). Due to heavy marketing and product branding, flash drives have been coined and associated with names such as USB drive, key drive, thumb drive, keychain drive etc.

SoftPerfect File Recovery

SoftPerfect File Recovery is a free and useful tool to restore accidentally deleted files from hard and floppy disks, USB flash drives, CF and SD cards and other storage media. It supports the popular file systems such as FAT12, FAT16, FAT32, NTFS and NTFS5 with compression and encryption. If your important files disappeared and you can’t find them in the recycle bin, try this software product and get the files back to life. Easy to use, no installation is required.

MAIN FEATURES

* Lightweight (268 KB only).
* Supports FAT & NTFS.
* Supports compressed and encrypted volumes.
* Supports most storage media.
* Easy to use, just run it!
* Completely portable, works from removable media, and does not leave any residual traces.
* Software is free to use for any purposes, as soon as the code is not modified.

Note that when you restore the files from the main boot-up Hard Drive, the success rate might be lower due to the considerations of the time to recovery parameter. The software is able to restore accidentally deleted files from built-in hard disk drives as long as two the following conditions are met:

1. The file was deleted recently and no writing was made on the volume after that.
2. So, if you delete a file from a system volume (e.g. C:’), there are little chances to restore it because the OS is constantly writing on this volume (logs, registry branches, etc).
