Dolphin Data Lab Released the World’s Top Data Recovery Assisting Tool

Dolphin Data Lab has released the world’s top data recovery assisting tool-Dolphin DR Assistant Pro. and Dolphin DR Assistant Pro. is Dolphin’s first software-only tool. Whatever data recovery tools you are using, Dolphin DR Assistant Pro. can help to enhance data recovery efficiency and data recovery success rate.

Dolphin Data Recovery Assistant Pro. contains 6 modules:

01: Invalid Files;
02: Extension;
03: N.S Image;
04: Database Repair;
05: Raid Analysis;
06: File Rename.

The module ‘Invalid Files’ is used to organize the data for data recovery cases with many bad sectors, weak heads, scratched surfaces, etc. When the data was recovered from these cases, many files are corrupted and there’re also some other invalid files too within the recovered data. At this time, Dolphin DR Assistant can be used to find out the invalid files, delete empty folders, delete invalid files of ‘tmp’, ‘tem’, ‘temp’, ‘~’, ‘?’, ‘Ink’, delete files if ‘DEADDEAD’ accounts for 50% or above of files’ hex data. Besides, users can delete the invalid files according to file types.

Module ‘Extension’ is specially used to correct the file extensions by changing the wrong extensions to the original correct extensions. For example, users can easily correct the .chk files in ‘FOUND’ folders to normal recognized file extensions so that users can open the files successfully.

‘N.S Image’ module is used to image the drives with non-standard sector sizes of 518, 520, 522, 528, etc to target drives or to a file with standard sector size of 512 bytes. Drives with non-standard sector sizes are usually used in NetApp, EMC, HP, Hitachi/IBM high-end storage devices, common data recovery tools cannot even analyze them or image them. These drives appear as server Raid drives and therefore, users need to image all of the drives and analyze them, find out the necessary parameters, rebuild the raid array and finally get lost data back. During the recovery process, the conversion from non-standard sector sized hdds or image files to standard sector sized ones is very important and this is why users need to use Dolphin DR Assistant ‘N.S Image’ module.

‘File Rename’ software module is very helpful in many data recovery cases. When the files lose their original names by raw recovery, recovery by file types, virus’s malicious modification, etc, users can use Dolphin DR Assistant to rename those files by extracting the date, Sheet name(excel), content, size. Our engineers are usually using ‘content renaming method’ frequently so that we can easily find out the wanted files we need.

‘Raid Analysis’ module is specially designed to generate one detailed engineering log report file which contains the parameters of ‘Disk Order’, ‘Raid Type’, ‘Block Order-Left/Right, Synchronous/Asynchronous’, ‘Block Size’, ‘Parity Delay’, etc. For skilled raid recovery engineers, it takes several minutes to find out those parameters from the engineering report file and then it’s easy to rebuild raid array and find all lost data back. Without this file, it may take several hours or longer and very complicated for some raid types and cases and it is not possible to get the raid cases fixed for beginners!

‘Repair DB’ module is mainly used to repair SQL Server corrupted databases. All users need to do is to select the corrupted database, select the repaired database save path and add the backup database and then the ‘Repair DB’ software will automatically repair the damaged database and save them.

  • The ‘Repair DB’ software module is mainly for repairing corrupted databases caused by bad sectors or scratched surfaces.

WD82EJRX-89AD9Y0 8TB WFS DVR Format Video Data Recovery

, ,

This is one very interesting CCTV DVR format video data recovery case study for one DFL user from India. This case was given to other data recovery companies with other CCTV DVR data recovery software but failed.

With any other CCTV DVR data recovery software tools, the users can only get videos of only 2MB or the videos are in a mess with different cameras in one video, so no effective videos at all.

This kind of failure is usually caused by the original dvr device format and about 500mb data in the beginning of the dvr drive is lost and therefore, users cannot find any effective/valid videos.

When this case was given to Dolphin user with Dolphin DVR Pro, the user applied for one remote support by Dolphin remote data recovery system. Dolphin engineer helped the user to find the starting address of the data area by Dolphin DVR Pro. and then started the video analysis in fast analysis mode and finally all cameras and videos were found and listed properly.

Users can select the cameras and videos to save. and in the coming new Dolphin CCTV DVR data recovery software, Dolphin DVR Pro. can search the data address automatically when it is lost and then it is more convenient.

HDD platter cleaning workstation Pro. Uses lower torque for platter cleaning purpose

,

HDD Platter Cleaning Workstation Pro. is one hardware-only equipment for data recovery purpose, it is specially designed to clean both 2.5 and 3.5-inch hard drive platters.

About the Torque Used by HDD Platter Cleaning Workstation Pro.

Compared with the HDD motor torque, HDD platter cleaning workstation Pro. Uses lower torque for platter cleaning purpose.

HDD motor can use higher torque because there’s flying height between heads and platters and it’s safe to spin the motor and get the heads to read and write properly. But for platter cleaning, it is totally different story:

When the platter surfaces are contaminated with dust, finger prints or other contamination, users must use lower torque cleaning toolkit and users cannot push hard to clean or never give too much pressure to the platter surface, any exceeded pressure on the surface contamination(dust or other particles) may cause scratches or permanent data loss. Dolphin engineers have tested a lot of motor torque options and then fixed one best working torque to spin the platter for platter cleaning purpose.

During the video instructions, users can see how our engineers are cleaning the platters properly with smart slight pressure by the cotton swab with or without absolute alcohol for the two types of cleaning cases.

HDD Platter Cleaning Workstation Pro. contains the following components:

1, Cleaning hardware workstation;
2, Platter fix nut for 2.5″ platter;
3, Platter fix nut for 3.5″ platter;
4, Power Supply AC Adapter.

2.He tried to unlock, but same scenario. No modules showed, only power up, two clicks, power down;
3.So he guess it can be module damaged. But couldn’t power up. He used only pcb and disable module 02, module 411 and kernel mode. But same clicking;
4.He found a donor PCB with same microcode HDD. Then used patient PCB to donor for test, donor drive can be detected as normal;
5.He put donor to PAITENT HDD. Luckily the patient drive can be detected. But after 10 seconds, gave one click and went to busy status. Not responding;
6.He managed to power on and off till enter the inside of FW program;
7.He disabled module 02. After doing that HDD shows module and no clicking. But once enabling module 02, start clicking again. He had to disable again to get all modules;
8.He edited module 02 manually and write it SA. Fortunately no clicking, smoothly worked with HEX 00;
9.DFL repaired the corrupted module 190, he then wrote it to SA and load to RAM. “missing node function ” and “repair nodes function” which built in version 2.31 were used for this case;
10. Two partitions are displayed properly, the image speed is quite good, up to 150M per second.
