what if you have software on 720KB disks that you'd like to use? the answer already seems apparent but i'm posing the question just in case

If the drive is 360k then it can only read single sided disks or one side of a 720k floppy. Pretty useless in todays world.

It can't even read one side of a 720K - i tried back then. This is due to the fact that doublesided floppies by default are processed with a side interleave per track. Track 0 Side A Track 0 Side B track 1 Side A and so on...
A special prepared disk (as some games had) could be made so that side A is still fully available for SF354 owners while side B is optional. IIRC Carrier Command used such to store optional digi music on side B for owners of 720k floppies.

Yes your right Simon. I must have been thinking of the double sided disks that appeared as magazine coverdiscs that could be read by single and double sided drives but as you say, they were specially prepared to work like that.

A single sided drive is fine if you're using single-sided disks, obviously. You can copy files onto them from a double-sided drive, save to them, etc. As long as the files are small enough to fit on the disk, of course.
