fdisk gives the followin (and it is correct):

        Disk /dev/hdb: 64 heads, 63 sectors, 528 cylinders
        Units = cylinders of 4032 * 512 bytes

           Device Boot   Begin    Start      End   Blocks   Id  System
        /dev/hdb1            1        1      499  1005952+  83  Linux native
        /dev/hdb2          500      500      528    58464   82  Linux swap

This is from df
        Filesystem         1024-blocks  Used Available Capacity Mounted on
        /dev/hdb1             879261  280075   548889     34%   /

The total blocks '87....' is wrong.

Anyone knows why?

You mean expr 280075 + 548889 = 828964 not 879261

: Anyone knows why?

by default ext2 filesystem reserves 5% for the superuser.

try
man tune2fs

Quote:>by default ext2 filesystem reserves 5% for the superuser.

: No, my disk is more than 1GB, this is the partition information.
: More than 100 MB is missing.

fdisk:
/dev/hda4          204      204      621   842688   83  Linux native

df:
/dev/hda4             815598  673352   100112     87%   /usr

So as you can see there is a bit of filesystem overhead  (3.2%)  which is
considerably less than your system.

Perhaps mke2fs was given the wrong (or read the wrong) device size when
making the filesystem.  

Have you tried running mke2fs on the device again?  (backup or transfer
the system first of course)

Maybe it will incorrectly report the device size.  You can specify the
filesystem size on the mke2fs command line.
