I have a 12.04 server install with 3 hard drives, all SATA.
I have checked the MB and AHCI is enabled. I installed the server with AHCI enabled on the MB.
When I remove a drive, it disappears from the system, when I plug it back in it does not appear in /proc/partitions even after a partprobe. I have looked around on the internet for a few hours and from what I can tell it should be detecting the drive automatically.
~# modprobe --list | grep ahci
What else should I provide and what suggestions do you have?
~# lsmod | grep ahci
