There are multiple techniques that can be used for recovering data from physically damaged hardware. Sometimes, parts can be replaced in the hard disk and although this may make the disk useable, there still may be some logical damage to contend with. A highly specialized disk-imaging procedure is used to recover every readable bit from the disk surface. Once this information is recorded and saved onto a reliable medium, the image can be safely analyzed for any logical damage. This technique will possibly allow much of the original file system to be reconstructed and saved.
Physical recovery procedures include: performing a live PCB swap where the System Area of the HDD is damaged on the target drive and is then instead read from the donor drive. The PCB is then disconnected while still under power and transferred to the target drive. Removing a damaged PCB and replacing it with a matching PCB from a healthy drive is another repair option. Sometimes, interchanging the read/write head assembly with matching parts from a healthy drive and removing the hard disk platters from the original damaged drive, then installing them into a healthy drive will suffice. Numerous combinations of these procedures may constitute a repair.
Certain data recovery companies have highly technical procedures available that are to be only completed by professionals and not an untrained individual. The manufacturer's warranty can be void if the hardware is tampered with.
Online or Remote data recovery, according to Servicios de respaldo Online, is the same as the regular software based recoveries except it is performed over the Internet without physically having the drive or the computer in possession. The recovery technician located elsewhere, gains access to the user's computer and is able to complete the recovery process online. It is a handy option so the user is not required to send the media or travel anywhere physically. This can be a convenient option, although it requires a stable broadband Internet connection in order to work properly and many third world countries do not have this option. It cannot be performed in any situation of physical damage and for such instances; the traditional in-lab recovery needs to be performed.
