Data recovery takes years and years of knowledge and understanding in order to make a successful recovery. People think that the data stored on the platters can be moved to a new drive and read like a CD. This is not true at all. If platters are moved, they are moved as a unit, Why?
Data is stored and written on the surface of the platters in cylinders. If the drive platters are moved one at a time the alignment of the platters is no longer readable and all data is lost on the drive. The swapping of platters is one of the last resorts in the repairing of the drive to read the data from the platters. In data recovery physical repair is one of the major problems for all DR technicians. Read more
Dolphin Data Lab is going to release new version of DFL-DE data recovery tool and DFL-DDP USB3.0 data recovery equipment.
Since the release of these tools, we’ve upgraded them regularly with new data recovery features or urgently to remove some bugs and now they have reached a higher level of stability and excellent performance.
As one professional data recovery hardware tool, it must have proper hardware design, clean and qualified hardware components, especially the main chip used inside the tool,clean and optimized hardware firmware codes controlling the hardware working principles,software codes, interface codes and codes to combine everything.Dolphin Data Lab has each step and each aspect strictly controlled by different engineers. We test, check and optimize all codes according to the new functions and features added to make them perfectly compatible so that the tools work at their best status. Read more
Since the launch of Dolphin Data Lab ‘Meet Dolphin’ activity, we have met hdd repair engineers and data recovery engineers worldwide in our office, they are mostly from USA, Japan, Pakistan, Malaysia, Australia, India, Tanzania, Canada, Lebanon, etc.
We are well prepared and ready to meet more engineers in the days coming at any time.
Engineers can bring the damaged hard drives, some difficult cases you meet in the data recovery labs and you can communicate and discuss with our developing engineers on possible causes of the failures, possilbe solutions to the failures and discuss on some new technologies and data recovery tips.

Congratulations to those clients who have been using DFL data recovery tools–DFL-DE data recovery tool, DFL-WDII hdd repair tool and DFL-DDP USB3.0 data recovery equipment.
With these tools, we receive almost each day happy feedback from our clients and they are repairing and recovering hard drive cases other data recovery tools cannot do: customers’ feedback and review on DFL data recovery tools here.
On average, users with our tools can fix two more cases each day and within one month, users can fix 60 more hdd repair or data recovery cases. If each case helps users earn USD200 on average and users can earn USD12000 more each month. Read more
To readers:
This data recovery method and steps are offered uniquely by Dolphin Data Lab, it’s not allowed to post it anywhere else without our permission.
We are using the following case study to explain the methods in details.
HDD ID: WD5000BMVV-11GNWS Capacity: 500GB
PCB number: 20607-701675-004
USB2.0 design
When the hdd was received from client, the engineer connected the hdd to the pc and check if it spun up normally, to find out if it clicked. The diagnosis proved it working fine. Read more
When a hard drive is dead, undetected or clicking, users need to repair it or get the lost data back. For this purpose, the very basic and first thing to do is to diagnose the hard drive and therefore, it’s quite necessary for users to learn how a hard drive works and what’s the hard drive booting sequence.
Hard Drive Booting Sequence
- Drive power on the PCB ROM returns status
- Drive self check
- Spindle motor spins up
- Heads are un-mounted from landing zone
- Servo reads the firmware stored in the ROM
- The firmware in the service area is read
- The firmware extensions are read
- If an error occurs during this process the back up copy of firmware is read. Read more
