Seagate 500GB HD showing 2TB, Unknown, Unallocated, Read Only Bad disk

[goneboy]

Hi.
I have a Seagate Goflex 500GB external hard disk. When I connect it to my laptop, it doesn't appear in my computer, and I have attached the screenshots of Disk Management and MiniTool Partition Wizard.
The hard disk is behaving this way when I removed it from my laptop while it was copying a file.






I do not need any data. I just want my hard disk to start working again.
Please help. Thanks in advance! High hopes!

Try using SeaTools for DOS to see if it can see and fix the HD.
Here is a tutorial by Arc:

It didn't do anything. It said that the hard disk was not found.
