I just received an 8TB replacement drive (for one that had a faulty fan.)
Model #SDPH62H-008T-NBAAD
I plugged into my iMac via USBc to USB cord provided.
The drive does not mount … Forum posts say to try erasing the drive first thing. This didn’t work in Mac OS Extended (journaled) or the default APFS format.
Both times I used the default Scheme - GUID Partition Map
No worky, what next?..
