#floppy database
#Records several parameters for different floppy sizes

#record format is
#fid eccmethod psize eccargs
# fid: floppy identifier=disk size in kb
# eccmethod: none for no ecc
# doffset: position of beginning of descr2k file on disk in 512 byte sectors.
# descrdown: descr2k length is 1.5 k y/n
# availk: available space for part data (and optionally ecc data) in kb
# eccargs: disk geometry arguments for ecor

#For historical reasons tbackup uses the following size rules for non-ecc
#disks in non-extended formats:
#psize calculation below 1 meg: substract 10 k.
#psize calculation above 1 meg: substract 17 k.
#this is a little bit waseful for 360 and 1200 k disks, they can store
#slightly more.
