Just inserted the drive and the HAL/udev deamon pick it up all on its own. My motherboard is a nVidia-based: 00:09.0 SATA controller: nVidia Corporation MCP78S [GeForce 8200] AHCI Controller (rev a2) And I am using the AHCI driver. CentOS 5.4, x86_64 (xen). It could be that the SATA controller on your motherboard does not support hotswap detection (not all AHCI controllers support hotswap detection). -- Robert Heller -- 978-544-6933 Deepwoods Software -- Download the Model Railroad System http://www.deepsoft.com/ -- Binaries for Linux and MS-Windows heller at deepsoft.com -- http://www.deepsoft.com/ModelRailroadSystem/
