They are Seagate Barracuda drives. One of the labels says "narrow SCSI". I've forgotten everything I ever knew about the interface, but I recall there was narrow, wide, and double wide?
If anyone might be able to stick these drives in a dusty old server and try to read them, I would gladly ship them to you with a PayPal following.
What I'm looking for is archives of some webpages I used to have, on my daughter's first year and a year long trip we took around the world with her. Compuserve disappeared and took the website with it, and I scrapped the workstation that might have held the backup, retaining only these drives. I think the machine was running whatever version of Windows was current in 2000, it was a PC (a server I built and used as a home computer).
