Certain SATA controllers have issues with AppleAHCIPort v329 (eg ICH10, 5 series, 7 series, ASMedia 1061)
Disks may fail to initialize, not readable or hot plug may fail.

See [Solved] Problem: HDD not supported and try new ICH patch.

"YOU MAY NOT INSTALL TO THIS VOLUME BECAUSE THE COMPUTER IS MISSING A FIRMWARE PARTITION''
but If I format it in APFS then no issue.. I want to go with macOS Journaled Extended..
