Dear Friends,
I solved the issue.I was sure that it was a problem with virus.I tried scanning with many anti virus programmes.But none detected it.Finally I downloaded Microsoft security essentials and it detected.It was trojan.
Name of the virus was Virus:Win32/Alureon.H.
Symptoms: Suddenly your harddisk become invisilble in Disk managmemnt as well as device manager.But visible in Expolrer.
Wont be able to take backup using windows backup.It will throw some error.
