Hard disk firmware basic & hard disk repair training

D4. 1 Introduction to hard disk firmware

  • What is firmware of hard disk
  • Micro code of hard disk firmware
  • Modules of hard disk firmware
  • Types of modules in hard disk firmware
  • Data modules, Management modules, Techno modules
  • Where firmware store in hard disk
  • What is negative cylinder/ track of hard disk
  • What is service area
  • What is inside hard drive system area?
  • Syatem area of hard disk
  • UBA modules(utility block addressing)
  • Module store in which head side
  • What happen if hard disk firmware module damage
  • When hard disk firmware damage
  • Common symptons of hard disk firmware failures

D4.2 Introduction to hard disk firmware modules in service area

  • Smart data
  • System logs
  • Serial number
  • Model numbers
  • Security data passwords for drive-possible encrypted info
  • Bad block table
  • P-List (Primary Defects List – manufacture defect info that does not change)
  • G-List
  • Program Overlays-firmware,Executable code,or updates
  • Zone tables
  • Servo parameters
  • Specific tables like RRO- (recalibrate repeatable run-out and head offsets)
  • test routines
  • factory dafaults tables
  • Recalibration code routines
  • Translator data:
  1. Converts logical and physical address to locations on the drive
  2. heads and track skewing info

D4.3 Problems when hard disk firmware is corrupted

  • Drive will not intialize
  • Drive is slow responding
  • Drive is not running properly
  • Drive will not be recognized by the computer
  • Head sticking clicking voice(may be due to firmware if hardware ok)
  • Shows up with wrong S/N
  • Show up with wrong Model no
  • Hard disk asked for password
  • Hang up on particular sectors
  • identifies fine but fails to read any data or boot up operating system giving i/o device errors
  • Smart error
  • Primary master hard disk fail
  • No operating system found
  • USB device malfunctioned
  • S.M.A.R.T. Capable but Command failed
  • Disk boot failure-insert system disk and press enter
  • Drive mount failure or some other hard drive boot error
  • The hard disk will spin up when powered on, but be incorrectly recognised / not recognised at all  by the computer
  • The hard disk will spin up & be recognised correctly by the computer but the system will then hang during the boot process

  • Disk boot failure-insert system disk and press enter
  • Drive mount failure or some other hard drive boot error
  • the hard disk will spin up when powered on, but be incorrectly recognised / not recognised at all  by the computer
  • the hard disk will spin up & br recognised correctly by the computer but the system will then hang during the boot process
