This is one successful data recovery case for one Dolphin user in Colombia. The patient drive was received without ID and users couldn’t find any data.
When users connected the patient drive to pc, it’s lucky that the drive was spinning smoothly and had no clicking noises, this one was very important to confirm because users couldn’t treat the physically damaged drives to firmware damaged drives, otherwise the wrong operation will cause permanent data loss.
After connecting the patient drive to DFL Seagate firmware repair tool and the COM terminal window output the following error messages:
SIM Error 2012
Diag Error Process Defect List Error
R/W Sense R/W error
No Host BSY
