Kindly please help. if u need my system log, please let me know how can i do that :)

I would try opening the case and connecting the drive directly to the computer. In fact, I would have done that long before trying to format or repartition the drive.

Often, it is the electronics inside the enclosure that fails but the actual drive is OK. If you had important data on it that you wish to recover, it still might be worth a shot to open the enclosure to see if the drive is OK. Opening the enclosure would most likely void any warranty.

If the data is not all that critical, then I agree with jumanji, if the drive is still under warranty, RMA it.

You will see a regular hard drive plugged into a small circuit board. Unplug the drive from the circuit board and then you can attach it to your computer as you would any other hard drive. If you are using a desktop then you should be able to connect it to your motherboard using data & power cables. If you are using a laptop then you will need a USB adapter.
