,

This is one successful Seagate hdd data recovery case study.The patient HDD was detected but the data area was not accessible.

ST500LT012 1SDM1 Data Encryption Data Recovery Steps Youtube Video

Patient HDD ID:
Model number-ST500LT012-1DG142
Family: Yarra_5400(75)
Capacity: 500GB
Firmware: 0001SDM1

With DFL Seagate hdd firmware repair tool, users can easily access to the firmware area, backup the rom and important firmware modules.

When trying to access the data area, all sectors were colored as purple and this meant the data area was encrypted.

The user tried some traditional methods and steps to repair the encryption issue but failed.

Next Dolphin engineer tried one unique firmware repair solution within DFL Seagate hdd repair tool-Remove Password 2(different from the standard password removal function).

Next the engineer powered off and on the patient drive, the data area was fully accessible.

ST2000LM009 Capacity 0 Seagate HDD Repair Steps

,

This is one Seagate ST2000LM009 hard drive capacity 0 firmware repair and data recovery case study.

This patient drive was not properly detected and the capacity was 0 and no data is accessible and there’re no typical com terminal messages of head damage.

To fix the capacity 0 firmware issue, users need to fix the translator corruption.

Before translator repair, users need to backup the rom, generate unlock rom, write unlock rom, power off and on, send unlock key to unlock the firmware area and next users need to back up the most important nglist.

Next users need to clear glist and regenerate translator. If com terminal repair doesn’t work, users can regenerate translator in ATA mode.

Next users need to fix the data encryption issue by DFL-Seagate hdd repair tool.

New Method to Read and Write ROM for Seagate and WD HDDs

,

Users have different options to read and write ROM from Seagate and Western Digital hard drives.

For many hdds, users can use firmware repair tools to read and write ROM directly.

For some new hdds, firmware repair tools don’t support to read or write ROM due to SED lock, MCU lock or other PCB issue or ROM chip issue. At this situation, users can only use flash programmer to read and write rom from the ROM chips.

For traditional flash programmers, users need to solder the ROM chips off and put the ROM chip to the chip holder to read and write rom.

Not all engineers have good soldering skills and Dolphin team offered Chip-on HDD Flash Programmer Smart, users just need to remove the PCB and then users can use the pin reader to read and write rom without soldering the rom chips off.

Now users don’t need to remove PCB, don’t need to solder the ROM chips off, users just need to install the HDD ROM programming clip adapter to the HDD and then users can use Chip-on HDD Flash Programmer Smart and its software to read and write ROM easily.

Users can read details of HDD ROM programming clip adapters here.

Seagate HDD Translator Regeneration Tips

,

Seagate hard drive translator regeneration is one very important firmware repair function within all Seagate firmware repair tool.

There’re two modes for Seagate hdd translator regeneration:
01: Translator regeneration in ATA mode;
02: Translator regeneration in COM mode.

Within COM terminal, users need to enter F3 T> to use m0,6,3,,,,,22 command to regenerate translator. But please note: users need to think carefully before using the command. Users need to clear g-list, need to reset smart, need to check the HDD failure symptoms, need to backup important firmware modules, etc.

In some cases, translator regeneration may cause partial sector access issue or data shifting issue and in many cases, users don’t need translator regeneration to fix the cases and recover the lost data. So don’t always use the translator regeneration command.

In some heads read-only cases, users need to use translator regeneration in ATA mode and access to the data area.

Within DFL Seagate hdd firmware repair tool, users can easily use the ATA translator regeneration under defects management and this one is very helpful.

How to Recover Lost Data from Western Digital HDDs with Bad Sectors in Firmware Area

,

There’re many Western Digital patient hard drives suffering bad sectors in the service area and users cannot operate on the firmware modules properly. At this time, if the firmware modules are corrupted, the patient drives become undetected, the data area becomes inaccessible, what to do to get the lost data back?

For some WD hdd recovery cases, users can swap the heads and the firmware area can be read properly. Some heavy drives or drives with multiple platters require adaptive rom to write to enhance heads’ read and write capabilities.

For some WD hdd recovery cases, users can use hot swap method by DFL-WD hdd repair tool to read original firmware modules and then use hot swap method again to recover lost data from original drives. The key is to find one good donor drive.

For some WD hdd recovery cases, users need to change the module size by DFL-WD firmware repair tool to bypass the bad sectors, this one is very helpful, no need to find donor head or donor hard drive;

For some WD hdd recovery cases, users can shift the bad sector firmware module by DFL-WD hdd firmware repair tool to one free good track without bad sectors and users can write the good module to the new track selected.
