Except for the "Drive label" field, this information cannot be changed from this page.

1. The "Drive details" group offers you the following information:
   
   1. Drive label: This is the file-system level drive label as you might have entered it on the &os2; command line using the LABEL command. &xwp; now allows you to change the drive label on the notebook page, without having to use the command line. This might be useful because many "File open" dialogs show you the drive labels, since they have no access to the WPS's disk object title.

      The drive level is limited to 11 characters and will always be converted to upper case.

   2. File system: the file-system type of the disk. This is probably either "FAT", "HPFS", "JFS", or "CDFS" (for CD-ROM drives). There may be other file-system types, if you have additional Installable File Systems (IFS's) installed.

      See "File systems" for an introduction to file systems.

   3. Block size: This shows you the size of the minimum allocation unit on the disk. That is, if a file of 1 byte length is created, at least this number of bytes will be allocated on the disk.

      For HPFS volumes, this number should always be 512.

      For JFS volumes, this number depends on what was specified when the volume was formatted. JFS allows block sizes of 512, 1024, 2048, and 4096, where 4096 is the default.

      For FAT volumes, the block size depends on the size of the disk. Since the file allocation tables on FAT volumes can only handle a limited number of blocks, for larger disks, more bytes have to be used for each blocks. As a result, the larger your FAT volumes are, the more bytes are wasted because of growing block sizes:

      Drive size      Block size
      <   16 MB          4 KB
      <   32 MB          2 KB
      <   64 MB          2 KB
      <  128 MB          2 KB
      <  256 MB          4 KB
      <  512 MB          8 KB
      < 1024 MB         16 KB
      < 2048 MB         32 KB

2. The "Allocation" group offers you information about the disk's usage. Total size, allocated and free space space are shown in bytes and blocks, where the "Bytes" information is the "Block" information multiplied by the "Block size" information above.

   In addition, you now get a pie chart showing you the free space on the disk (in green).
