That's true from what I've read too, although nVidia has written some SATA drivers for Windows which supposedly handle hot-swapping, but it requires that you set the SATA subsystem in the BIOS to RAID mode. Our 5015M-T+ servers have Intel AHCI enabled in the BIOS: atapci1: <Intel ICH7 SATA300 controller> port 0x30e8-0x30ef,0x30dc-0x30df,0x30e0-0x30e7,0x30d8-0x30db,0x30b0-0x30bf mem 0xe0000400-0xe00007ff irq 19 at device 31.2 on pci0 atapci1: AHCI Version 01.10 controller with 4 ports detected Also, I could have sworn the official SATA specification didn't list or support hot-swapping until the SATA-II revision. -- | Jeremy Chadwick jdc at parodius.com | | Parodius Networking http://www.parodius.com/ | | UNIX Systems Administrator Mountain View, CA, USA | | Making life hard for others since 1977.
