[gentoo-user] Changing volume name of a FAT partition

[gentoo-user] Changing volume name of a FAT partition

Is there a way to set or change the volume name of a FAT partition
without reformatting it? When using HAL with KDE or Gnome Volume Manager
to display icons of USB devices, it uses the volume name, if present, as
the icon text, so it would be useful to be able to change this to give a
more meaningful label.

That sounds like a job for dd (be careful though).  I used conv=notrunc but that shouldn't be necessary for a normal block device.

$ dd if=/dev/zero of=floppy.img bs=1k seek=1440 count=0
0+0 records in
0+0 records out
$ /usr/sbin/mkdosfs -n 12345678901 floppy.img
mkdosfs 2.11 (12 Mar 2005)
$ strings -t d floppy.img
      3 mkdosfs
     42 B12345678901FAT12
     91 This is not a bootable disk.  Please insert a bootable floppy and
    158 press any key to try again ...

$ echo -n "abcdefghijk" | dd of=floppy.img bs=1 seek=43 count=11 conv=notrunc
11+0 records in
11+0 records out
$ strings -t d floppy.img
      3 mkdosfs

[gentoo-user] ReiserFS4

[Ryan]

Does anyone know of or know where to get the limitations of ReiserFS4? 
I've looked at the reiserFS4 and it does not list things such as Num. of
subdirs that a single dir can have, num. of files a single dir can have,
etc.  I am looking for something like this: (only for ReiserFS4 instead
of ReiserFS)
Got this from: http://everything2.com/index.pl?node_id=510028

   1. You can store a maximum of 4,294,967,296 files in a reiserfs
      partition.
   2. You can put no more than 2,147,483,648 files in a directory.
   3. The maximum number of subdirectories inside a directory is 64.536.
   4. The maximum file-size is 17.6 terabyte
      <http://everything2.com/index.pl?node=terabyte>s on 32 bit
      architectures.
   5. You can have as much as 4,294,967,296 link
      <http://everything2.com/index.pl?node=link>s to a file.
   6. And finally your file system overall maximum size will be
      4,294,967,296 x 4K blocks, i.e., 17.6 terabytes.

Aha! I looked in dosfstools but didn't think of mtool. Thanks.
