I just recently received a WD Green 2TB of the EADS series Mfg. 2010
it has an extra black plate and screw to hold the spindle from the top
well this disk doesn’t shake at all when flat or vertical
all the other WD disks I have, that don’t have this black plate and extra screw
shake like crazy when mounted vertical and smooth as silk when mounted flat
but jump all over the table when mounted vertical
it’s a 0.025¢ screw and a 1¢ plate
standardize the Mfg. put this on all disks and get 0 RMA for disk induced vibrational damage
