"depends"

If the SATA controller supports hotswap ATA will notice when you yank  
the drive and detach it properly from the system (ATA wise, if  
mounted you get into trouble). Also it will autodiscover any SATA  
driver added, again only on supporting chipsets (and those I know how  
to handle).
