ST33000651NS HDD Data Recovery Case Analysis

Patient HDD ID:
geonix (ST33000651NS)
Firmware G009
Heads and Platters: 5 platters and 10 heads
Family: MantaRay

Patient HDD Failure Symptoms:
Patient HDD was dead, no power, pcb had been changed with donor pcb 100611023 REV B, original rom was written to donor PCB
Data area was not accessed after PCB swap, data was encrypted

>>
As for this Seagate ST33000651NS dead hdd data recovery case, it is not enough to swap PCB simply to patient HDD, it has also encryption key stored in the Main chip, users need to swap the Main chip from the original dead PCB to donor PCB to decrypt the data.

Compatibility Request for PCB Swap of WD20NMVW-59EDZS7

“Hello,

I need confirmation about compatible SATA PCB for recovery purposes.

Here are the details of my drive:

Model: Western Digital My Passport Ultra (Metal Edition)

Product Number: WDBEZW0020BBA-0A
Serial Number: WXC1AC6AS94Z

Internal HDD Model: WD20NMVW-59EDZS7

PCB Number: 2060-771961-001 REV (USB native)

The drive powers on and is detected via USB, but it is extremely slow and has bad sectors. I need to convert it to SATA for imaging and diagnostics.

Questions:

Does your Western Digital USB-to-SATA PCB Package include a compatible SATA board for 2060-771961-001?

After installing the SATA PCB, will I need to transfer the ROM chip to access the data?

Because this is a My Passport Ultra Metal Edition, does the hardware encryption remain active after PCB conversion?

If encryption prevents access, is the DFL-URE USB3.0 required to extract or decrypt the data?

Thank you.”

The compatible SATA PCB for this 2060-771961-001 REV is 2060-771960 and it is included in the Western Digital USB-to-SATA PCB Package. The patient may suffer the common slow firmware issue or weak head issue. If it is firmware related bad sector slow issue, it’s easy to fix by DFL WD firmware repair tool. If it is weak head or physical bad sector issue, users can only set up head map and image good heads and good sectors first and then weak heads and sectors.

DFL-URE is able to extract the data at non-encrypted status but not recommended for one single case.

SSD Data Recovery Knowledge Base: Recover Deleted or Formatted Data

Is it possible to recover data from deleted or formatted SSD? This depends mostly on if the Trim command is turned on or off. In order to help to improve the performance of SSD, the TRIM command, GC(garbage collection) and wear leveling technologies are adopted. These technologies will erase all the marked unused/deleted/formatted data blocks and get these blocks to raw available space which means the previous data couldn’t be recovered any more.

Please note: Trim cmd is turned on by default and this one is not friendly for data recovery and if users need to recover the lost data, users need to turn it off.

Besides, pls. don’t write any new data to the patient SSD so the previous data won’t be overwritten.
