I've seen systems that emulate 2-port master/slave controllers in IDE/Legacy mode and renumber drives differently in that mode than in AHCI mode. That BIOS setting only affects the mainboard controller and with a 24 disk ZFS pool I assume those disks are connected to some other controller. Regardless, I'd stay away from the RAID mode too though since there's a risk of overwriting some sectors of your system disk. It would've be interesting to know if that setting has changed though... Is there any indication that the BIOS settings were reset during the disk swap? (Date/time being way off for example). Did you verify that the SSD is still connected to the lowest numbered port? ATA_STATIC_ID was removed back in 2015 if I remember correctly so unless you run an ancient FreeBSD version I wouldn't rely on that mechanism. Perhaps you can tell us what kind of system this is in case someone on the list has a similar system and know its quirks. Also, if you're running a GENERIC kernel or not. /Morgan
