sata

Does anyone know of a method I can use to programmatically detect if a SATA hard drive has been unplugged? Our file system is mounted in READ-ONLY mode when we need to detect the removal of the drive. We noticed the other day that we were able to unplug a hard drive and everything continued to run without a hitch until the next time we attempted to read from a file on disk.
