Passport Ultra - Formatting failed return value =0x1 message

[Bennette]

Hello,

I am trying to format and use my Passport Ultra 1TB. Using WD Quick Drive Format it gives the error Formatting failed return value =0x1 message

Firmware updater says it cant see the disk.

Disk shows in Disk Utility but when you format it it says ‘Unable to write to the last block of the device’ and I can see that the Partition Map is set as unformatted. I have tried to create a partition on it using both GUID and as a Master Boot Record but that comes back as not being able to unmount the disk

Any advice please, I would like to use this disk!
