Since you're using 'cp' rather than 'mcopy' I'm inferring that
you put a Linux filesystem on it to start with, e.g. using
mkfs -t ext2 /dev/fd0H1440
I just did this on a floppy and got the message that there were
184 inodes 1440 blocks
72 blocks (5%) reserved for superuser
So you're not going to get more than 184 (perhaps + the 5%) files
onto a floppy with ext2 on it
I don't know off-hand what the maximum number of directory
entries is on a floppy with msdos filesystem on it, but I'd
be surprised if it was much different.
So that's where your limit is coming from.
There are higher-density options if you use floppy devices
like
/dev/fd0u1743 /dev/fd0u3840 /dev/fd0h1494 /dev/fd0u1760
/dev/fd0h1660 /dev/fd0u1840 /dev/fd0u1920 /dev/fd0u2880
/dev/fd0u1660 /dev/fd0u3200 /dev/fd0u1680 /dev/fd0u3520
/dev/fd0u1722
(selected from the output of ls /dev/fd0*), but I don't know
(a) How many of these would work with a given floppy and drive;
(b) How many more inodes (if any) you would get.
Anyway, on the assumption that you don't absolutely have to
get everything on a single physical floppy, just use 2 or more
and never mind the empty space!
Cheers,
Ted.
