As a major storage medium for user to store video files, DVD is quite vulnerable to damage and data loss. Fortunately, now we have solution to recover lost DVD data namely MiniTool Power Data Recovery - a powerful data recovery program newly developed by MiniTool Solution Ltd..

Writing modes of DVD:
Different types of DVD adopt distinctive writing modes usually including:
Disk At Once, DAO for short mode masters the disc contents in one pass, rather than a track at a time as in Track At Once which allows any amount of audio data (or no data at all) to be written in the "pre-gaps" between tracks. One use of this technique, for example, is to burn track introductions to be played before each track starts. A CD player will generally display a negative time offset counting up to the next track when such pre-gap introductions play. Pre-gap audio before the first track of the CD makes it possible to burn an unnumbered, "hidden" audio track. This track can only be accessed by "rewinding" from the start of the first track, backwards into the pre-gap audio. DAO recording is also the only way to write data to the unused R-W sub-channels. This allows for extended graphic and text features on an audio CD such as CD+G and CD-Text. It is also the only way to write audio files that link together seamlessly with no gaps, most notably progressive rock CDs, which often feature the music segueing into each other with no breaks between each song.

Track-At-Once or TAO is a recording mode where the recording laser stops after each track is finished and two run-out blocks are written. One link block and four run-in blocks are written when the next track is recorded. TAO discs can have both data and audio at the same time. There are 2 TAO writing modes: Mode 1 and Mode 2 XA.
However how could user recover lost DVD data from diverse data loss scenarios? Fortunately, now we have solution to recover lost DVD data namely MiniTool Power Data Recovery - a powerful data recovery program which is newly released by MiniTool Solution Ltd. with small size and simple operations supporting Windows 95, Windows 98, Windows 2000, Windows XP, Windows 2003, Windows Vista and Windows 7, etc. If needed, user could download it at MiniTool Power Data Recovery Download Center.



Running this software, user could see five modules in the main interface: "Undelete Recovery", "Damaged Partition Recovery", "Lost Partition Recovery", "Digital Media Recovery" and "CD/DVD Recovery".

In this interface, all disk partitions are searched and listed here. And two buttons are available on the right: "Open" button is to research and recover deleted data in circumstance that partition functions normally; and "Full Scan" is designed to recover damaged or lost data from damaged, unreadable and accidentally formatted or deleted partition which enjoys a comparatively slow speed than "Open".
