I have 3 older WD My Book Essential drives from 1-2 TB all quietly working fine. I bought a new 3TB WD My Book (pictured as My Book Essential but arrived as My Book, not sure if That is already an issue) and started to combine my data. One week later the interface PCB this and the drive is useless. WD does not care about your lost data, theywill not send you the replacement PCB or return your drive to a new enclosure, I can simply return it or void my warranty and take the drive out. I chose the Latter. Problem 2, apparently even when you do not choose to encrypt your drive, it is silent always encrypted. So even once removed it can not be read by Directly connecting it to your computer. Tried to use the PCB from one of my older drives, But They Have Changed the encryption version. Back to two options, reformat and lose all data now, or be extorted to try buying a second drive, voiding its warranty immediately and hope it has the same version controller PCB - as WD will not Provide this information. I am not happy, and will not buy WD external drives again.
