SATA hot swap feature works only with controllers basing on Silicon Image chip set from our in house testing. Other controllers that are not Silicon Image based may not support hot swap. You may consider adding one of the Addonics Serial ATA host controllers to your systems to ensure the hot swap capability. New controllers from Intel and other suppliers may finally support this feature. Please verify with your controller manufacturer if you need to have hot swap in your application. Hot swap is supported in Windows 2000 and XP only. On other OS, drive can be removed without crashing system. But replacing with a different drive can result in crashing the OS.
