Data Recovery from hard drives is a highly complex science that requires deep knowledge of hard drive technology, appropriate equipment and - of course - skilled experience. hard drive data recovery
It is NOT a DIY procedure.
Modern hard drives manipulate firmware locks and encryption techniques employed by the manufacturers, making data recovery a big challenge even for experienced engineers.
A specialized data recovery lab will follow these steps to recover data from a crashed hard drive:
- Reception of the hard drive and signing of the confidentiality agreement NDA
- Discussion with the customer, obtain crucial information regarding the conditions under which the failure occurred, the history of the disks life, and the needed data (type, location on the disk) that have to be recovered. At the same time, all information that may be important is collected, such as whether the disk adopted some type of encryption, whether it was a member of an array, etc.
- Run a detailed diagnostic. The check includes the examination of the individual functions and components of the disk, such as the condition of the board, surfaces, read heads, etc.
- Inform the customer about the results and get required approval.
- Εκτέλεση της βασικής διαδικασίας ανάκτησης, ανάλογα με τη βλάβη. Για παράδειγμα, αν ο δίσκος παρουσιάζει βλάβη στις κεφαλές, τότε θα πρέπει να επιλεγούν προσεκτικά τα κατάλληλα ανταλλακτικά και να μπει στο Clean Room για αντικατάσταση των κεφαλών).
- Modification of the microcode (firmware) to properly assimilate the new parts and not to be rejected.
- Targeted disk imaging
- Extract data from the clone.
- Evaluation of the final result and rechecking where needed.
- Inform client about final result and get approval.
- Copy the data to a new hard drive and deliver to the customer.
