Are sata hard drives really hot swappable?

I just installed a Kingwin KF-91 Black Aluminum SATA Mobile Rack on my desktop. I got it working fine. I put the drive in after it started with no problems. What happens when i remove drive when its running? will it mess things up?

If it's your only drive, expect the computer to stop working. If you installed the AHCI Serial ATA drivers for your OS and have AHCI enabled in the BIOS, you should be able to hot swap those drives just like any external USB drive or flash drive. I believe you are actually supposed to be able to hot swap/plug drives even without AHCI, but I had no luck with out those drivers. They are generally *not* the ones installed by default. If you need to upgrade the drivers, read: http://forums.pcper.com/showthread.php?t=444831

Yes it will mess it up and your computer will stop working.

There are several things that have to occur to make a system's hard drives hot swappable.
One of the key things is you have to have a type of RAID that allows drives to be hot swappable.
