I suppose you could put a label on the drive (with tune2fs), then mount 
it by LABEL=xxxx...  I dunno what else to suggest.

linux's crappy way of handling disk device names is one of my bigger 
gripes about it.     its really messy in a SAN environment where there's 
several storage controllers.   /dev/sdf could be almost -anything-.    I 
prefer the c1t1d1 notation of traditional Unix systems like Solaris, 
although there still can be issues identifying the channel #s
