I wanted to check the status of a drive. I installed it in an external enclosure but it was not seen. I went to BIOS and I got the message that the external drive was not recognized because the computer must be set to AHCI + second choice?, I set it to AHCI but then the computer would not boot. My three choices in BIOS were AHCI, ATA (computer original setting) and legacy. What do I need to use this drive, external or otherwise. I don't know if the drive in question has been formatted but since the computer doesn't see it, I can't determine that.
