I purchased 9 passport essentials as same model(WDBAAA3200ABK).
They work good as normal external drives.
But In WD smartware, they aren’t detected except one drive.
so that I cannot use drive lock function.
I already have checked other Mac but same issue.
The trouble shooting I have had are below,
Check all drives formatted as Mac OS Extended (Journaled).
Firmware and software update to all drives
Connect other Mac
Appriciate if you have any solutions.
