This news is to tell all clients who don’t have Dolphin Data Lab data recovery tools that all our tools are full-English programs.

We have recently got some doubts from some new clients asking if our data recovery programs are full-English because they saw some Chinese texts on our programs in some demo videos.

Here we must tell all new clients please don’t worry about this problem at all. As one world-class data recovery tools manufacturer and supplier, Read more

Within our data recovery lab, we have received many WD USB hard drives and they are mainly Western Digital 2.5″ My Passport Portable Hard Drive and 3.5″ My Book Essential External Hard Drives.

For WD USB hard drives, they adopt one hardware encryption technology by the USB controller chip and the algorithm of this technology make all data written through the USB ports become encrypted,whether you set password or not.

Within our data recovery cases, engineers meet often the failures of USB hard drives:

Power on the hdd, it spins up without clicking, but the USB port couldnot be detected or the capacity couldn’t be recognized and this is mainly caused by firmware failure and at this time, the hdd has slow response, slow detection, busy, etc. Read more

It’s a tradition that Dolphin Data Lab keeps in a close communication and cooperation with all our users and even many new clients who don’t have our tools are suggesting us to meet their new data recovery demands.

We are here reporting to all our users the latest working process of our research and development on new data recovery tools and solutions.

1, Working on the new version of DFL-DDP
2, Working on the new version of DFL-DE;
3, Working on the final stage of releasing DFL-STII;
4, Working on new USB hard drive data recovery solutions
5, Planning on the new upgrade of DFL-WDII.
6, Working on some other new data recovery and firmware repair tools.

Seagate is one of the biggest hard drive manufacturers besides western digital and seagate hard drive repair and seagate data recovery cases are very common within all our data recovery labs. This article will introduce to you the basic and important firmware modules of Seagate hard drive.

There’re two parts of firmware located on the platters’ minus tracks and ROM chip on the PCB, we call the part on the platter SA-service area or FW(firmware area).

A complete Seagate hard drive firmware contains  APP, Cert, Cert table, ATA(7200.10 and .9 contains ATA 0 and ATA 1) and vendor modules and ROM module. Read more

New clients can make an appointment with us at a convenient time and we will offer demo by teamviewer so that users can check how our tools work and what detailed functions are included inside. Read more

Head and Platter Swap Tutorials


SCSI hard drive is not used by common PC users but used in some special fields such as audio recording, video editing, web servers, media streaming servers, gaming systems.

The following is one SCSI hard drive opened in clean room environment which has a capacity of 4.3GB and 12 platters and 80 pins. It is 80-Pin SCA-2 SCSI hard drives / Discs / Disks (Hot Swap) for servers with hot-pluggable back-planes.We seldom find such kind of drives now and therefore post it for sharing: Read more

We have handled many WD PCB1692 series 2.5″ hard drives with some tips entering the safe mode.

For 2.5″ PCB1692 or series after, it’s not a problem to read ROM when the hard drives are recognized. But it’s a problem when we tried to write ROM and it’s quite often to make the PCB dead by writing ROM to it.

The success rate is not high to enter safe mode by short connecting on 1692 series. The best way to enter safe mode for 1692 series is to separate the PCB, anyway, pls don’t remove the PCB.

Users just need to remove the two screws on the PCB to control the heads contact and insert one biz card and then power on and wait until the motor stops spinning and then the hdd enters kernel mode and next the ROM can be read and written.This also helps to read firmware modules for some hard drives with bad heads.

Dolphin Data Lab is offering comprehensive professional and most cost-effective head and platter swap tools and components to all clean room data recovery engineers.

Many people are asking what kind of physical head and platter swap tools to buy to work on those dead hard drives due to head damage or motor stuck and this article will give you one general idea of the head and platter swap tools Dolphin Data Lab is selling. Read more

Head and Platter Swap Tutorials


When users are going to replace heads or platters in a clean room environment to get the lost data back, it’s a must for these users to learn about each physical component what it is and how they work.

Today let’s check some of the most important physical components: Heads, Platters, PCB.

The platters contains the data and the heads contains read heads and write heads to read data from platters and write data to the platters. PCB is another very important physical component, it contains not only some of the firmware codes like ROM, but also controls the electrical components to offer power to the hard drive running.

When we are talking about dead hard drives, we usually refer to those which doesn’t spin up at all, no hdd working sounds, no response and they look dead. Actually some of these so-called dead hard drives are still alive and these drives can be still repaired and recovered.

If the driver IC is burnt, the PCB won’t power up at all, users can swap with one donor driver IC or swap the whole PCB with original ROM/bios chip transferred;

If the PCB is burnt or other electrical components of hard drives are burnt, the hard drives won’t be powered on and won’t spin up at all. At this time, users just need to find one compatible PCB with the same PCB number from the same family and put on the dead hard drives and then manage to regenerate the original ROM to recover the data;

If the motor of the dead hard drives is stuck, users need to disassemble the hard drives and remove the platters to a donor hard drive to read data from.
