(I can't afford a hard disk yet.) I run MOST (but not all) of my 'active' floppies at 10 SPT for the space; and MOST (but not all) of my 'archive' floppies (non-image backup) at 9 SPT because its 'approved' and so feels safer. The problem isn't insurmountable (the system knows what the SPT of the mounted flopsies are); it's just finding a clean, release-independent method of getting the info into the cache routine, without using the offical TRAP call (since you're already in a TRAP handler) and without imposing unacceptable time penalties (like duplicate reads of Sector 0. Biggest problem is that my present schedule isn't leaving me any time for playing with my ST, and the cache is pretty far down my play list. Sigh.
