Media information: Seagate 11 generation hard drive, model is ST31000333AS
Fault description: head damage
Data recovery process:
This kind of hard disk head damage is difficult to recover, the pick is particularly serious, and the success rate is particularly low. This type of disk matching head needs to look at the firmware version number of the hard disk, and find the firmware version number is similar or the same. Sometimes such a magnetic head does not necessarily match successfully. To do such hard disk data recovery, it often requires multiple hard disks of the same type.
Fortunately, Darth data recovery has accumulated a number of spare parts libraries after years of data recovery, and many basic spare parts can be found. The Darth Data Recovery Engineer finds the same type of spare parts in the spare parts library and replaces the heads in the Class 100 open clean room. Changed a firmware version number is similar, after replacing the disk, the instructions still can not, restore the head to the spare disk and found normal, indicating that the spare head is no problem, but the faulty disk does not match, the engineer found a similar The spare hard disk is tested on the data recovery device after the magnetic head is replaced. The hard disk can be recognized, and the data is successfully recovered after one day.
Data recovery results: 100% data recovery
Advice to customers:
Hard disk companies like this one have a powerful spare parts library. Do not re-energize the hard disk when it is damaged to avoid secondary damage. Do data recovery to find professional formal data recovery companies.
