How to Remove the hard disk

1 Expansion card

The SE/30 has a Processor Direct Slot (PDS) for expansion cards. If there is anything installed here, it is easier to remove the card chassis completely, rather than trying to work around it. This network card has a board controlling the SE/30’s ports, as well as the PDS board.

2 Drive caddy

The hard disk sits above the floppy drive. Remove the power and data cables from the drive’s rear and undo the drive caddy. It’s held in place by two screws underneath the caddy but they are set quite far back. Use a long screwdriver, or tape a screwdriver bit to a stick.

3 Maximum capacity

The SE/30 shipped with a 40 or 80MB hard disk, but you could replace it with any 3.5-inch, half-height SCSI drive. Mac OS, up to version 7.5, supports volumes as large as 2GB and if you install 7.5.2, you could use a 2TB drive. The SE/30 was often used as a server.
