Seagate HDD data recovery example. This Seagate hard drive came for data recovery and evaluation. It was pulled out of an external enclosure that was dropped by accident. Seagate 7200.12 series. This is very common problem with external hard drives. Damages we see are so severe that it would be impossible to recover data from this hard drive, no matter who you deal with, even NSA.
Because this Seagate HDD was working (spindel and platters were rotating) while it was dropped, gravity caused heads to touch platter surfaces. This created circular scratches, that have developed to a complete magnetic material scrape off…
Majority of modern drives, including Seagate HDDs do have free fall sensors. Because of sensors, drive firmware will attempt to park heads immediately once free fall was sensed. In many cases there is just not enough time for it to move heads away from platters to parking ramp. Result is on the picture.
This actually could of have been less severe if drive was not turned on after the drop! Do NOT turn on your drive after you have dropped it. You will end up in situation when data recovery will not be possible! Have professional data recovery company evaluate it and don’t attempt DIY. Any work on hard drive internals has to be done in clean room or clean box. Otherwise it will only cause more damage. Even a little dust particle, mist, liquid drop, fingerprint or hair on platter can cause severe damage. It will develop in to serious problem. Sadly, this Seagate hard disk drive is toast, no way to recover data from it.
