I am trying to format my external hard drive which contained some important data and was earlier formatted as exFAT. The external hard drive (Transcend 1TB) was bought 6 months prior and it does not get mounted on Ubuntu. But the drive is visible in disks utility. Following is the image:
I tried this link for solution as the question contained the same error as I am getting while formatting the hard disk.
As per the link stated I installed gparted after opening it gives me error Input/Output error during read on /dev/sdb.
I ignored the error and after I select my device from drop down of gparted following image is the outcome.

Can I retrieve my data and device? If I can not retrieve my data can I format the disk for reuse?
Or is the disk completely damaged?
