- There are no intelligent 5.25 drives. They look different and connect to your

- I have a //e and two IIgs'es, and two '83 vintage Disk II's and two of the grey
- 5.25's like you can get nowadays. I have both the old Disk II card and the new
- card with the DB-19 to go in the //e. I have tried out the drives on these
- machines and here are my observations:
-
- Any drive connected to a card in a //e will spin until you hit reset if there
- is no disk present. Both the grey drives connected to the new card and the Disk
- II's connected to the old card do this.
-
- Using an adapter to connect a Disk II to the IIgs' drive port, it is able to
- tell whether it can boot from the drive and pass control to slot 5 if not. This
- is just like the grey drives do.
-
- So you can conclude that "intelligence" is a function of the drive interface
- rather than of the drive itself. So swapping drives will cause you to need
- either an adapter or a new card for the //e and will gain nothing.
