Under the old file system (as opposed to the Fast File System, FFS) each
sector was 512-bytes long.  Out of that 512-bytes, 24 are used for file
system redundancy thus you were left with 488-bytes for user data in each
disk sector.  The 880K represents the total amount of disk space on a
normal, old file system floppy which included the file system overhead.  The
838K represents the maximum potential user disk space on the disk.

Neither.  Everything's OK.  It just a matter of view point as to how much
"data" is on an Amiga floppy.
