Whoa!!!!!
Here is how it works
The first sector on the disk has some OS pointers and then at byte 446 starts
the partition table. There are 4 16-byte entries and then two signature
bytes at 510 and 511.
If there are to be any extended partitions, one of those entries has to point
to the first sector of the extended partition.--this is like hda2.
Now in the first sector of partition 2, there are two entries. One points to
the beginning of hda5(physical data), and the other to the next extended
partition, (hda6), where the process is repeated int the first sector of that
partition and so on...
One of the flaws of 7.2 is that if you make an extended partition with no
physical partitions inside, diskdrake will say your partition table is
invalid and offer you a blank one--that's because the first sector of the
extended partition contains formatting characters or random data. We have
closed that hole in 8.0 Diskdrake now complains but then recovers the table.
explore2fs or similar programs should be able to see your linux partitions,
if you have the latest versions that support sparse superblocks.
