When a hard drive is damaged physically, unforntunately spare parts can not be found inside domestic computers or electronics. These spare parts must be obtained from another compatible hard drive, for which the data recovery engineers are tasked with sourcing so they can replace the broken piece of the patient hard drive, this has to be done in a Certified Clean Room (see Our Tools), to not run the risk of contamination.

The following are guidelines to maximize compatibility when searching for Head Readers, which is necessary to perform a Head change during the data recovery process. Please note that there is no way to garuantee that a donor hard drive will be 100% compatible, however these guidelines will increase the likelihood of the donor hard drive being adequate.
