western digital drives on an adaptec controller by chance?

when i was at aol a few years back we had several hundred, may a thousand 24 bay supermicro boxes with adaptec controllers. about once a month a box would turn up for service with a hand full of corrupted files. this happened on mirrors, raid 5, and raid 6. 

this even happened to one of my osol thumbnail servers (about 1b images on the pool).  we always suspect a wd-adaptec problem but the vendors just pointed fingers at each other. 

it did seem to occur on the hardware platforms and our sample size was in the tens of thousands.
