When it is connected internally what is the SATA mode? IIRC only AHCI is supported. If it is SCSI or RAID it would not detect it.
drlucky,
I understand SCSI and RAID, but I am not familiar with SATA in a SCSI mode or RAID mode, I can’t see why this would be. On a Win10 system, where would I look for this? I’ll continue to look to see if I can find.
Thanks!
Edit 3/20/2019: Ok, I looked in the system BIOS, it showed setting SATA=AHCI.
