Hard Disk Drive Failure :-

HDD (Hard Disk Drive) Failure or Boot Disk Failure 

(A) Here user must run the CMOS set-up for "IDE HDD auto detection".

(B) If the HDD is not detected, then user should check the connectivity of HDD controller.

(C) After fixing up the connection properly, if again the HDD is not detected then user can change the IDE channel, i.e. (that is) from IDE 0 to IDE 1.

(D) If the HDD Is Detected but system is not booting from c:/>, in that case user can first try with the transferring system booting from A:/>.

(E) If C drive display "Invalid Drive", in that case user should run the "Fdisk" command to create the partition.

(F) If the partition already exist then user can just try by making the primary Dos partition active.

(G) If the partition is made properly and system is transferred, then user should scan the entire HDD for virus problem.

(H) User also run the diagnostic tools like NDD, NE, DE, DM for checking the HDD track '0' and other sectors.

(I) After attempting all the possible reasons user must check the master-slave jumper setting for proper configuration and must check battery voltage for CMOS set-up. Even the existing HDD can be checked at another PC. In case for the problem of on-board IDE Chanel, the problem can be solved temporarily by adding an IDE-IO controller card at ISA slot of the motherboard. (Here, on-board Chanel should be disabled from CMOS set-up.)
