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.

WD SMR HDD WD20EZAZ 810011 Data Recovery Case by DFL User in Sri Lanka

,

This data recovery case study is shared by one of our experienced, smart, friendly and kind users from Sri Lanka, his name is Dananjaya who offers very professional data recovery services in Sri Lanka.

HDD ID Information:
Patient drive: WD20EZAZ
PCB: 2060-810011

Reported symptoms
According to the drive owner, when he was copying wedding pictures to HDD, windows OS popup error massage called “not enough space”

HDD Repair and Recovery steps:

1.Once our user received the HDD, he checked. He found that when power on HDD, it spin up, but then two times’ clicking and power down. Like platter damage;
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.
