Applet for detecting the filesystem type.

[Sameer Naik]

Hi,

fdisk -l /dev/sdc shows me the following output.

   Device Boot      Start         End      Blocks   Id  System
/dev/sdc1               1         584     3926016    5  Extended
Partition 1 has different physical/logical beginnings (non-Linux?):
     phys=(0, 32, 33) logical=(0, 34, 43)
Partition 1 has different physical/logical endings:
     phys=(488, 227, 59) logical=(583, 195, 59)
/dev/sdc5               1          79      524288   83  Linux
/dev/sdc6              79         157      524288   83  Linux
/dev/sdc7             157         235      524288    b  W95 FAT32
/dev/sdc8             235         313      524288    7  HPFS/NTFS

Here the last (two) fields report the partition type, not exactly but
to some extent. Meaning "Linux" could mean ext2/ext3 and so on.
However it seems to atleast zero in on a set of partition types.

I do not understand what you mean by "if you can
guarantee, that at your system partition types in MBR corresponds to
real partition types"
