[Case Study] Detailed Steps for Extracting Data from Burned & Watered Hard Drive of DVR System


[News] SalvationDATA was Awarded Another New Patent from USPTO


[Software Update] VIP V1.0.15.7996 New Version Release for Better DVR Forensics

“Intensive Read” Force to Recover the Incomplete Data

“Intensive Read” can be explained as forcing to read. In order to enhance the readability of HDD with bad sectors, the program improves the intensity of working heads with a group of special instructions. Normally, that method is used in the application of such important data recovery by force. But we do not suggest that method due to degradation caused potentially. Only for a few of important files( such as evidence in court, database files, etc. ), the data recovery can have a good result beyond the normal mostly. For example, in an important case of investigation, the image recovered cannot display normally as following, but the second is a good result processed by intensive read. Pic. 1#, normal recovery method on the HDD with bad sectors Pic. 2#, intensive read on the HDD Recurrence: tutorial on “Intensive Read” hand-by-handNext, we will take a Seagate HDD( Model NO. ST94011A, SN: 3KW1AA08 ) of laptop as an example of data recovery. 1. Inspection of HDD externalFirstly, w

10 Rules for Best HDD Performance

As a important component of data storage on PC, unfortunately HDD occurs errors and failures with increasing frequency. One time of HDD corruption, it will not only cost time of OS reinstallation or replacement fee, more importantly, but also loss of valuable data. In terms of personnel, it is irrecoverable memory. In terms of corporation, it is a heavily disaster. Therefore, it is very important to monitor the healthy condition, to make daily maintenance, to prolong the lifetime of HDD, to secure data storage, to improve your work efficiency and even to maintain the normal operation of the whole company. Please check step by step as following rules. 1. A good quality power supplyUnstable voltage can heavily impact the PC, specifically the HDD. If the voltage jumps up and down, it will make an unstable running speed of drive’s disk and even worse the lifetime of HDD. Causes of unstable voltage can be concluded as the following two points. Firstly, the power supply of PC has a bad q


DRS Core Function VIII – Surveillance Video Data Recovery

This module is specially designed for surveillance video data recovery. The surveillance video data recovery function of DRS can be explained as following: Ø Support DaHua, HIKVISION and other tens of brands or formats Ø Recover the deleted, lost, covered and fragmented video Ø Apply the own algorithm to recover data from non-standard monitors Ø Extract data by network port of monitors for the extracting in place solution Ø Recover and extract files from non-standard operation system of diverse monitors For more information about Data Recovery System, please contact us: info@salvationdata.com


DRS Update of Underlying Code & Ordering Style

Comparing with the last update, the latest version of DRS has been highly optimized on operation and underlying code compiling and running. Optimized Function & Thoughtful Guidance 1. Optimized Hexadecimal Editor ModulePragmatically Hexadecimal Operation Module has been added to onto DRS. That module makes users able to make “Jump” and “Syn-Jump” on HDD table, and show us an easy way of viewing Disk Partition and viewing files in hex. “In Hexadecimal Editor Module, you can jump directly to the ‘new position’ inputted.” 2. Redesigned DR Report with MD5 Verification Newly AddedAccording to earlier feedback from our customers, the DR report has been redesigned in formation. To mainly readjust the order rules and classification methods of the report, it has largely improved the readability and practicability. In addition, the latest DRS adds MD5 verification which provides customers various and valuable method of verification. “New style of ordering in DR report” 3. Designat


Upgrade to, we are preparing for the final update of DRS for you!

The long-awaited Data Recovery System is going for final checks and upgrades before its official launch. Having upgraded to, Data Recovery System has increased two additional functions for photo viewer and shortcut key. In addition, some programs are further optimized. Two additional functions make easier operation 1. Photo Viewer: View, Rotation, ScalingUnder thumbnail mode after file scan, the large image can be shown by double-click, and it can be shrinked and rotated. Direct preview of the deleted picture 2. Shortcut key: Search, Skip, RefreshHaving been added 14 shortcut keys, Data Recovery System is simpler to operate. What is more, R&D team will consistently add more shortcut keys for users to improve efficiency. Furthermore, the version has optimized 5 performances in data recovery and image process. Say, the direct view in hexadecimal content can be implemented by right-click on file. And by adjusting some parameters, the new version has made some hard disk


DRS Core Function VI – Physical Recovery

DRS supports imaging in bad sectors, providing solutions to stuck disk when imaging and even to inoperable sector data etc. You can customize the configuration of accuracy to load sector data and image copy-failed sectors. The process of image are displayed on real-time basis giving solution to bad sector imaging through anti-stuck technology.Main Features:Ø Applied UDMA-133 transform technology, and the testing copy speed reaches 12GB/minØ Support copying data for HDD, USB Flash, CF cards and TF cards by IDE/SATA portsØ Monitor the whole imaging process in real timeØ High-speed copy bad-track HDD with IDE/SATA/USB portsØ Precisely read sectors on bad-track HDDØ Support reading data by forward/backward or reading repeatedly in order to extract more dataØ Use different colors to show imaging fast or slow during the imaging process Unlike physical repair, the physical recovery module mainly provides solutions to bad sectors and a series of issues when imaging, whic


DRS Core Function VII – Video Data Analysis

Storage media supported by DRS are variety of types. Besides the traditional data recovery of HDD, DRS is able to analyze the data on the storage device of surveillance video. That ability built by 5 core functions, Ultra-playing, Video-retrieving, Super-transcoding, Map-tracking and Data-retrieving.When DRS works on the analysis of video data, it can extract and track the moving object based on video frame variation. By this way, to get traces of all moving object would be entirely easy. In addition, it is capable of retrieving the stationery frame and shortening video viewing time. The video analysis function of DRS can be explained as following.1. DRS can be served as a ultra-player and transcode tool in that it can support mainstream video format and most of the surveillance video format, and can convert it into standard AVI format.2. With the broadcast functionality by retrieval, it can ignore the stationery frame and adjust the kinetic frame speed.3. Support video retrieval, DRS


To Extract Data From the Hard Disk with the Damaged-head Shielded -- the Latest Technology From SalvationDATA

Data storage in the Hard Disk Drive (HDD) is processed by magnetic read/write heads. Due to the time cost and other uncontrollable external factors, the head is easy to be damaged, the platter is easy to be worn, even much worse mechanical failure happened. Mostly, the mechanical failures include abnormal noise, stiction, disability of seeking, pause in spin, none spin once power on again. Normally, we can install a suitable head instead of the bad one to fix those failures. But in actual operation, the failures cannot be fixed in many times even the damaged-heads replaced. The reason might be unmatch of the heads or some platters worn even the heads are matched. So the drive cannot work in normal. Even worse, after the update, the new heads are damaged again when the heads read the the worn platters. Regarding those failures, SalvationDATA conducts a research and gets a fresh technology to read data from the drive by shielding the damaged-head. The technology is used for data
