People tell me they see
"The drive reports both 250609664 and 250640384 bytes as its capacity"
But this just means that it has capacity 250640384.
(If one computes a geometry from this, and takes sector size 512,
and 64 heads and 32 sectors/track the number of cylinders will
become 250640384/(512*64*32) = 239.
If one then again multiplies 512*64*32*239 the result is 250609664.
In other words, the kernel message is a bug, there is usually
some rounding when computer some fake number of cylinders,
and the resulting CHS capacity will be a little bit smaller
than the actual one.)
So, in ide-floppy.c this message is entirely superfluous,
and the code throws away 30 kB of floppy space.
But I would like to see what you get in the 100M case.
