Because you need some sort of hotplug or other logic to trap the error, instead of letting the storage device being reported as "removed" from the system. When you use 3Ware card as a "dumb" JBOD device, you lose _all_ of its features for hot-swap. That's because it no longer hides the "raw" disk and its state from the system. So when you use it in JBOD mode, and the volume = disk, you need to use _another_ facility to hide the "raw" disk status from the system. That's where hotplug comes in, and you need to set it up proper. This has been a repeat theme. People don't understand that all of the 3Ware "advantages" like hot-swap and hiding the "raw" disc status _only_ work when you use its hardware arrays. -- Bryan J.
