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.
