That's what i do all the time :) All my disk are 1.44 MB and work just fine (in my 1.44 MB drive) ?! Anyway, ELKS probe code should be able to handle some really exotic formats as well (for example single-sided media with 18 sectors per track and 80 tracks = non-standard 720 KB format) - it does rely on "standard" formatting scheme though so you could feed it a floppy deliberately formatted in a way that would confuse the probe (and consequently cause problems to doshd code). It also counts on sectors being formatted to 512 bytes (which is normal, standard format, only exception i can think of is lame copy-proetction some compaines used to employ .. this is not an option anymore with CDs replacing floppies as installation media). Bottom line being: use standard formats and everything should work just fine :-))) Blaz Antonic
