This AS 800 has a seagate st32171wc 2.1 GB ultra SCSI drives (2 shadowed). I wonder if I can get new bigger replacement drives? I can get seagate st32171wc, but I think they are all used. This AS 800 has a hot swap cage, so all the pins have to be positioned to match. But, I guess any 80 pin ultra scsi will work?
