How to format an external encrypted hardisk?

I had a laptop with windows 7 on it which I fully encrypted its harddisk with Symantic Encryption Desktop,

I removed the harddisk to external case. Now I would like to format this external harddisk.

I tried accessing it from another laptop with windows 7 but it won't show as hard disk under Computer.

However I can see it in Disk Managment.

But when I try to to intlize it, I get this error: (Data error (cyclic check)
