Check if the Hard Disk power connector and SATA connector is properly connected.

check sata/pata and power cables.. check if jumper are in proper place.. check for bad sectors..

pls share specs of your rig .

[whitestar_999]

if S.M.A.R.T values are ok then it is most likely a power/connector related problem.

Try a different sata port on the mobo - it worked for me once

[sandeep410]

I already tried switching but problem still persits
2 out of 4 hard disk has the problem

if possible use that HDD in another system.

is it a pata HDD? check with a new cable. happens usually when cable is badly twisted.

[sandeep410]

Its a sata,i already said i have switched with 4 cables

[clmlbx]

did you check for Bad sectors as I said earlier ?

[sandeep410]

scanning disk doesnt show any bad sectors

^^ check the SMART status of those HDDs - use HDTune pro or your HDD manufacturers official diagnostic tool for that.

Make sure your hard disk is fixed firmly. Loose cable (power or data) is the most likely cause. Also try a different SATA port on the mother board.
