This is a newer problem we are seeing with Western Digital SMR drives. They use a new firmware design that is similar in some ways to SSDs. The drive might have a problem with the secondary translator, when that happens it will appear to function fine but all sector reads are returned as zeros. I don't know of any way to fix your problem without a resource backup when the drive could read data. There is always the chance someone has figured it out and maybe they will offer their service here.

You can find more information about Western Digital SMR technology here.

+1 any problem with secondary translator drive will only return zeros.
Also keep an eye on imaging speed, if its running at max, drive is not even trying to read a sector.
TRIM like function is another twist to these SMR families
