Maybe it's not partitioned. Have you tried to mount /dev/sda?
Sir,
I have tried to mount the USB drive to "/dev/sda" and I have getting please specify valid filesystem on dev sda.

# parted /dev/sda print that will show you what the status of the drive is, if you then need to make a filesystem : mkfs /dev/sda - make sure you dont have any data on the disk you care about first.

What does "fdisk -l /dev/sda" return?
If there's nothing on the drive you care about try repartitioning with fdisk and making a file system using "mke2fs", or "mkdosfs" if you want VFAT.
