This is one common and easy to fix data recovery case study for Dolphin users with DFL WD HDD firmware repair tools. HDD ID: WD20EZRZ-00Z5HB0; SN: WD-WCC4M0AYXCXY, Capacity: 2TB.
This case study was fixed by Dolphin remote support engineer for one Dolphin user from Argentina.
When the patient hdd was received, the data area was fully blocked and if user scanned the hdd, the hdd was full of bad sectors. The user connected the patient HDD to DFL-SRP WD firmware repair tool, the ROM and SA are read without problem but after testing the firmware modules, one issue was found: all firmware modules are good except firmware module 148.
