I bought a new Maxtor Atlas 15k_18WLS 16GB 68 pin hard drive for $10 U.S. a couple of years ago off E-bay. It works great and is really fast. It doesn't even get hot with the AmigaOS unlike a certain other OS that thrashes the hard drive constantly. It's used with a Cyberstorm MK3 cybppc.device 44.71. I would get a Guru on bootup with SFS but PFS works great.
