Thanks. The Plexus converter is a good deal at that price. But, I have an old AOpen MZ855 wherein the disk is mounted East-West - with virtually no space either end of the disk!
I've got an older system that runs IDE, and want to upgrade the hard drive to something that runs very quiet, also with good performance. Any capacity equal to, or above, the existing 400GB. Low cost would be good too. Must be IDE.
