I've just got a wde18300 Ultra2 LVD scsi drive. I thought it would be wise to ask someone with a few more clues than me if anything BAD<tm> would happen if I put it into the internal slots in an Sparc Ultra2 that had a ST34371WC - SCA 80 pin single ended ultra-1 - in it before hand. They have the same SCA 80 pin interface.
