Try using Phil Turmel's excellent lsdrv script; I've attached the 
version I use on EL5, but I hacked it about to work on such an old 
distro so I wouldn't swear it will work on more recent distros; Phil's 
original that does work on more recent distros can be found in the list 
archives around 6 November last year in the thread "Determining which 
spindle is out of order".

Cheers,

John.
