Thanks for the info!!!
Well, since I have 20 3.5" 1.44mb drives, I guess the best thing is to just use these.
I'm still trying to get a grasp on the 5 1/4" issue, mainly due to transfering data from the older media to the 3.5" drives, but also, just so I understand;
I have 2 1.2mb drives. So, as long as I copy from the 35/40 track 180/360k drives to the 1.2mb drive and never use those disks in the smaller drives I'm okay. And was I right guessing that I would use ds/dd 360k media in the 1.2mb 5 1/4" drives? Or since these disks would not be used in the other drives does the media matter?
Thanks for all the help so far,

Interchange with 35/40 track drives is an issue, they are not directly
compatible without tricks. Using them in DECB is possible but again,
interchange with others is an issue.
Unless you already have a cache of 80 track 5.25" drives, I'd just use

Maybe once I get a grasp on this, I'll create a tutorial for those like me who have spent entirely too much time in the World if Windows machines...
