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
