Samsung Hard Disk RecoveryIn Most of the cases, burnt PCB is one of the most common problems.
Samsung drives are very vulnerable to power
overheating and power surges. Often bad power supply unit combined with
power streak is enough to burn spindle driver chip on the electronics and make
data inaccessible. Should this occur the computer would reboot itself or
shutdown completely, you would normally notice acrid smell and smoke and the
drive will no longer spin up. In case your patient hard drive is in the same

such drive or read any data from it you would get "Primary Master Hard Disk
Fail", "No operating system found" or "Disk boot failure" or some other SMART
error on boot up.
Samsung hard drives clicking/knocking
The drive spins up and the head starts clicking right from the beginning with a
constant or intermittent sound. Most often this a sign of damaged heads and it

head assembly from matching donor. Don't try to open the drive by yourself -
most likely you will damage the platters and make your data unrecoverable.
Samsung drives have bad sectors problem too.
After some period of time magnetic media starts to degrade and bad sectors
appear. Whenever the drive hits such unreadable area it could start freezing,
ticking, scratching and sometimes even clicking. This leads to further damage to
the media and causes more data loss. As soon as you start experiencing such
symptoms while reading important files stop your computer immediately and
consider talking to a professional. Any further attempts would just add up to
