2￿Troubleshooting￿Procedures￿

The￿HDD￿or￿system￿board￿may￿be￿the￿reason￿of￿a￿HDD￿fault.￿Either￿of￿these￿two￿components￿

may￿be￿damaged.￿To￿determine￿if￿the￿computer’s￿HDD￿is￿functioning￿properly,￿perform￿the￿

following￿procedures.￿Figure￿2-15￿outlines￿the￿process.￿Start￿with￿Procedure￿1￿and￿continue￿

with￿the￿other￿procedures￿as￿instructed.￿

Procedure￿1:￿ Diagnostic￿test￿

Procedure￿2:￿ Connector￿and￿replacement￿check￿

Procedure￿1￿ Diagnostic￿test￿

Run￿the￿Diagnostic￿Program,￿which￿will￿automatically￿execute￿the￿HDD￿R/W￿test.￿￿Refer￿to￿ Chapter￿3,￿Tests￿and￿Diagnostics￿for￿more￿information￿on￿the￿program.￿

If￿an￿error￿is￿located,￿go￿to￿Procedure￿2.￿￿If￿an￿error￿is￿not￿located,￿the￿HDD￿function￿￿is￿ functioning￿properly.￿

Procedure￿2￿ Connector￿and￿replacement￿check￿

The￿HDD￿module￿or￿system￿board￿may￿be￿disconnected￿or￿damaged.￿￿Disassemble￿the￿ computer￿following￿the￿steps￿described￿in￿Chapter￿4,￿Replacement￿Procedures,￿and￿perform￿ the￿following￿checks.￿

￿

Check￿1￿ Make￿sure￿that￿the￿HDD￿module￿is￿securely￿slotted￿into￿the￿system￿board.￿If￿the￿ problem￿persists,￿go￿to￿Check￿2.￿

Check￿2￿ The￿HDD￿module￿may￿be￿damaged.￿Replace￿it￿with￿a￿new￿one￿following￿the￿ instructions￿in￿Chapter￿4.￿If￿the￿problem￿still￿exists,￿perform￿Check￿3.￿

Check￿3￿ The￿system￿board￿may￿be￿damaged.￿￿Replace￿it￿with￿a￿new￿one￿following￿the￿ instructions￿in￿Chapter￿4.￿
