@BC I tried the Disk Management, Selected the 2TB WD HDD, it was not initialised. Tried to initialise the disk and got access denied error. I hope you read my initial posts, that I tried the same thing using Disk Utility on a MAC and dd command to clean the hard drive.
@nara Tried the diskpart as well but without success. I am actually checking Spinrite if that helps. Will let you know the results soon.
