Disk Manager suggests it’s not initialized, try initialize and receive error " The Media is Write Protected"
WD Quick Formatter Version 1.2.0.7 detects the device as “My Book 1110 SN:” serial number is blank in this. Error received when attempting to run the format “WD external drive format failed”
I try and see if a firmware update will help,
WD Firmware Updater Version 3.0.1.1
Title to error "Erase My Book Essential; too many attempts. it gives me the option to Erase the drive, I accept the condition and select “Drive Erase” receive error that Firmware update failed.
Diskpart lists the disk as Online at 2047GB

Subsequent to those test I continued additional test on Linux, equivalent results achieved.
I have also tried this on a Clean Build of Windows 7 x86 with the same results.
I think it’s time WD came up with a solution to this obviously common problem.
