So when you confirm it is physical head damage which requires you to perform the head swap to extract the lost data, the next step is to find a donor head or donor hard drive. What’s a donor hard drive for Samsung head swap? From the old families before Victor, Puma, Verna & etc

Data Recovery came along with data loss, developed along with appearance of different forms of data storage medias and attracted with digital times’ fueling; D.R tools started from in-house customized data recovery program or personal data recovery program owned by military or some special data-sensitive agencies or few talented individuals; DR tools turned to be commercial data recovery software or equipment by its great potential market value. Data Recovery usually starts and develops well in big IT developed cities of developed countries or developing countries.

When we are dealing with different computer forensic cases, we usually need to perform disk imaging. Disk imaging in computer forensics is different and much stricter than the common data copy and disk image, it must ensure the copied data is exactly the same with available simutaneous verification reports  such as Hash or MD5 verification codes. Computer forensic disk imaging is sector by sector image imaging all the contents of original disk including the location of the data, the file system, the lost or corrupted data, the hidden data, etc.

It’s one very important step to find a donor PCB or donor hard drive for repairing and recovering hard drives. You may need to swap the PCB, exchange the head or find a donor firmware from the donor drive. This article may help you learn more on the donors of Seagate Barracuda 7200.10 Galaxy2D .

It’s very important to read some hdd error codes when you are using some Seagate hdd repair tools like pc3k or hd doctors within their cmd mode.  If an error is detected, a drive outputs to terminal its code and brief additional information.  E.g.:    “Code – FE  Track 19A1.3.06E  Sns E00  Rty F7FF.FF.80FF  Rtf 1C00” – “FE” error. The error codes are explained as follows: 00: No error 03: Calculated CRC doesn’t match the expected value 11: Spin error 12: Ramp load error 13: Offtrack 14: Write fault 15: Rd/wr seek timeout code 16: Seek timeout 17: “False” AMDET (mis-timed) 18: Bad burst error code 19: Bad Grey code 1A: Early sync code 1B: Missed am 1C: Failed the servo defect screen threshold 1E: Target generator sector error 1F: Physical sector error 20: Skip write detected using servo burst 22: NRZ freeze occurred (A=A’)&(B=B’)&(C=C’)&(D=D’) 29: Thermal Asperity errors padded in test 36.

HotSwap is a popular method used for data recovery in case of problems with HDD service area. Essentially, it means replacement of a PCB on recipient drive with an initialized PCB from a donor drive.

*  ID – module identifier. *  Copy – copy number

It’s good to save in data recovery field for personal data recovery cases by downloading free data recovery tools, that usually means free data recovery software . The following data recovery software is another tool we recommend for personal cases with logical hard drive failure including one of the following: Files emptied from the Recycle Bin, lost due to hard drive crash, formatted or damaged hard drive, virus infection and other unknown reasons.

Seagate drives can function both in regular mode (Normal mode, when a drive during start reads its firmware (microprogram) and data from disk surface and initiates the user interface) and in Safe mode. In the latter case, the drive does not spin-up the spindle motor and does not read the service information switching to terminal command mode.

Worm ：Application Network；Malicious software which is a stand alone application. Worm is Often designed to propagate through a network, rather than just a single computer
