Symptoms of HDD PCB Failure & HDD Firmware Corrupted

DATARECOVERYUNION.COM01 mins

Most people can’t distinguish the HDD problems cause by HDD PCB failure and HDD firmware corrupted. Now we offer some advice as below, please refer:

HDD PCB Failure Symptoms:

When a hard drive fails due to PCB failure, the drive usually cannot boot up or there may be an inaccurate display in the BIOS of the hard drive’s information. Also power may not get to the hard drive and as a result it will not spin up.

HDD Firmware Corrupted Symptoms:

  • The drive will power up normally (no ticking noises, errors etc) but will not be recognized by the computer.
  • The drive will power up normally and be recognized correctly but will report a size of 0 bytes
  • The drive will power up but report SMART errors on boot

6 Reasons BIOS will not detect or recognize your drive (6)

Hard disk drive not enabled in biosReason 6: Hard disk drive not enabled in the BIOS

Most personal computers display a brief message about entering System Setup soon after the power is turned on.  System Setup is also called the “System BIOS” or sometimes the “CMOS Setup” – each is a name for the same thing.

For example, on Dell systems you will see “F2=Setup” in the upper right hand corner during the computer boot-up.  This means to press the F2 key to enter Setup (the BIOS).   Different computer manufactures have different methods to enter Setup, so please check your system documentation for specifics. How to access/enter Motherboard BIOS

System setup is where the date and time are stored and where startup preferences like NumLock or Passwords are defined. In addition, many hardware settings are defined in System Setup.

In particular, hard disk drives are often controlled here. At the simplest level, hard drives are numbered in Setup as Drive 0, Drive 1, etc or sometimes as Primary Master, Primary Slave.  Which ever way these are named, they have a basic ON / OFF setting (sometimes AUTOMATIC or something similar).  If your drive is not detected it may be because it is turned OFF in System Setup.

In most cases, the boot drive is Drive 0 or Primary Master.  When you add a second drive to the system, it may be need to be enabled by turning it ON in System Setup.

Glossary of Samsung Hard Disk Drive (Letter C)

DATARECOVERYUNION.COM04 mins

Samsung hard disk driveCache Memory
Part of the Personal Computer (area of DRAM) that transfers data between system elements with different performance characteristics (increases processing speed)

Capacity
The maximum amount of data that can be stored on a specific HDD, expressed in gigabytes (GB) / megabytes (MB)

Capacity Barriers
On certain occasions (primarily with older Personal Computers) the full capacity of the disk drives in a PC is inaccessible. This may result from a combination of Hardware, BIOS, and Operating System constraints. General solution is either to upgrade the system BIOS or install Driver software

CD-R (also CD Recordable)
A recordable compact disc that holds read only data that cannot be changed

CD-ROM
A pre-mastered compact disc that contains data thanks to an extra recording layer built into the structure of the disc. Once written, the data cannot be erased

CD-RW (CD Re-Writable)
compact disc that allows you to re-record data up to 1000 times

CHS
Cylinders, Heads and Sectors. A term used to describe the properties of hard disk drives, the CHS information for a drive is stored in the computer BIOS

Clean Room
Dust free environment, which is required when manufacturing hard drives

Closed Loop (also track following servo)
Control system, which reflects if the head is in the correct position over the track, if this isn’t the case, the actuator is instructed to adjust its position (in real time)

Component Design Life
The amount of time the drive should operate without any problems

CMOS
Complementary metal oxide semiconductor. CMOS chips are extensively used in computer systems because of their low power consumption. They can also operate over a very wide range of supply voltages. They are, however, susceptible to damage by static electricity and care is required when handling them

CPU
Central Processing Unit, the brain of all modern computers. The microprocessor chip that executes programmed instructions

Crash
breakdown in hardware/software in a system

CRC
CRCCyclic Redundancy Check; part of a sector which detects if parts of a string of data is missing within the sector. It is a method of testing that the data retrieved from a disk is without error. When data is written to disk, a special check number (CRC) is calculated, based on the data itself, and stored with it. As data comes off the disk, the CRC is re-calculated and compared with the stored CRC. The two match if no errors are present

Cylinder
The vertical position of all the heads over the (various) platter(s) on a specific track of a disk drive, forming a vertical cylinder
