When pc boots My wdc hard disk shows sec master hard disk S.M.A.R.T status bad backup and replace

Not very helpful info! I would try tapping f12 on booting up which takes you into the Dell Diagnostics mode. Then come back here.

The BBS Popup is to boot from a selected device, if you have Windows on your Hard Drive just boot from your HDD.

Test all leads that attach to your hard drive including electrical extensions,IDE,SATA

the leads from your ((motherboard to your hard drive)) make sure they have a secure dust free connections and are not faulty or just replace them they could be faulty

make sure all leads that are attached to your drives dvd\cd 3 1/2 inch floppy have secure connections and are not faulty or just replace them they could be faulty ?

even something as small as an electrical extension or a faulty fan lead can cause this problem

a computer needs all of the data and electrical current to travel through every working device and to have an end to be able work properly

motherboard and a hard drive any leads between them will fail before your motherboard or your hard drive if its a flat ribbon 40 pin type IDE replace it this will be the first to fail check all electrical extensions make sure they are securely seated even the cd/dvd floppy drives need to have current go through make sure these drives are working

make sure the CPU central processing unit has thermal paste and dust free and is securely seated

make sure your computer ram modules are securely seated with no dust in sockets also Cmos battery has charge with no dust in the socket some motherboards cmos batteries are soldered in
hope this helps you

S.M.A.R.T. is a way to tell if your hard drive is going to die soon. Since it says BAD, it means the hard drive is going to die soon so you should backup all your data and then replace the hard drive with a new one or a working one that isn't dying.

If you have Lenove Desktop then there must be 100% sure the Hard Disk with Western Digital make and has gone faulty. No option left but replacing the HDD. You can contact with Lenovo support for the same issue if it's under warranty.
Please rate and vote me if you got my suggestion helpful and informative.

Hi rmirish,

The hard drive has built in SMART diagnostics to check itself to make sure all is well. If the SMART is showing status BAD then the hard drive is either either starting to go out. Your best bet is to try to backup any data (if you have any) on the hard drive and replace the hard drive.

Hope that helps,

Take care,

Michael

A failure message from the SMART system of this nature indicates that a catastrophic hard drive failure could be imminent. Without delay, back up ANY data you want to keep. This error isn't going to go away, and is being reported by the drive controller.

Whilever you can access the drive, move any data you want onto another media (such as DVD or external USB hard drive) because chances are it's not going to work much longer. You need to look at buying a new hard drive as soon as you possibly can, and migrating the data to it.

Files and Settings Transfer Wizard will be able to backup your data to another media.

i think this is a os problem or hardisk problem change check hard disk
