TDC Data Recovery has four modules, as follows:
Deleted Recovery
When a file is deleted from your computer, its contents still exist.If you manage to start an data-undelete process before Windows overwrite the original file, the Deleted Recovery of TDC Data Recovery can do the job for you.

It can get deleted files back even after you have emptied the recycle bin.It can recover the deleted Word, Excel, PowerPoint, photo, email, database, and all document formats and folders in Windows 2000, XP, 2003, Vista, 2008, Windows 7 and all the other Windows Operating Systems.

Formatted Recovery
When you format a disk, the operating system deletes all bookkeeping information on the disk.

Formatting a disk does not mean deleting the data on the disk, only the data on the address tables.Do not be panic, however, if you accidentally format a disk that has useful data.A computer specialist should be able to recover most, if not all, of the information on the disk.

You can also use TDC Data Recvery that enable you to recover it yourself.
However, the previous discussion applies only to high-level formats, the type of formats that most users execute.In addition, each hard disk has a low-level format, which sets certain properties of the disk such as the interleave factor.The low-level format also determines what type of disk controller can access the disk.

Almost all hard disks that you buy have already had a low-level format.It is not necessary, therefore, to perform a low-level format yourself unless you want to change the interleave factor or make the disk accessible by a different type of disk controller.Note that performing a low-level format will delete all data on the disk.

Partition Recovery
Whether partition can be recognized by system or not depends on the partition table.

If partition table is destroyed or deleted accidentally, you will not see the partition you need.But in fact, the partition is not lost.
Partition Recovery of TDC Data Recovery is designed for easily recovering files on mistakenly deleted or lost partitions.It can scan the entire disk to find every possible partition on it for recovery.

When you select this recovery module, select the file types you want to recover and then you could see a list of physical devices that are connected to Host Computer.Choose the device from which you want to recover data and start searching partitions on it.After the Partition searching process completes, TDC Data Recovery will display a Partition List Page.

Just select your lost partition and search it.You can got all the lost files back on the invisible partition soon.

RAW Recovery
TDC Data Recovery can recover deleted, lost files and corrupt or missing drive where file system is severely corrupted or destroyed.
You should use RAW Recovery option in following cases:
? File system data structures of a drive have suffered serious corruption or overwriting and data recovery software cannot scan such drives.

? Deleted Recovery, Formatted Recovery and Partition Recovery cannot locate lost files and folders.
? Files were deleted "long back" and cannot be identified because of over-writing to file system data structures.
? Recently deleted files are not recovered because of severe fragmentation.

This is a common problem in FAT file system drives.RAW Recovery can discover such deleted files and folders from the temporary copies created by the application software or the operating system.
RAW Recovery scans every sector of your storage media for the lost files that you want to recover and displays them in a tree according to the file type and size.

TDC Data Recovery software can scan the drive in RAW mode and locate the files without the aid of file system data structures.
