HD is 80 GB and I clone my original disk (40 GB) to this one which is
80 GB so it likes HD was 40 GB.

You cloned it badly, probably with dd. This would have overwritten the
partition table of the 80G with that of the 40G disk.
Much better is to copy with rsync. Set up the partitions on the new disk
and then copy everything over with rsync. A bit slower, but it MD5 tests
to make sure the transfered file is identical to the original file.

Never just clone a drive.

In that case, you just need to make the extended partition larger, as
another poster suggested. This will not lose any data and allow you
to create more logical partitions.

Your current table:
> Device Boot Start End Blocks Id System
>/dev/hda1 * 1 255 2048256 83 Linux
>/dev/hda2 256 765 4096575 83 Linux
>/dev/hda3 766 1275 4096575 83 Linux
>/dev/hda4 1276 4427 25318440 f Win95 Ext'd (LBA)
>/dev/hda5 1276 1785 4096543+ 83 Linux
>/dev/hda6 1786 2167 3068383+ 82 Linux swap
>/dev/hda7 2168 2422 2048256 83 Linux
>/dev/hda8 2423 2677 2048256 83 Linux

With fdisk, delete the partitions in reverse order: 8, 7, 6, 5, 4,
then recreate 4 extended with same start and new end number; recreate
your partitions 5, 6, 7, 8 in order with the _same_ start and end
numbers you had before.

Now you can create new partitions in the extended area.

Remember, nothing is written to the disk until you hit 'w' ;) So take
care and start over if you make a mistake. It is important to perform
this type of operation in correct order (delete from end to target) to
be able to recreate identical partition table layout without disturbing
the data areas.


Otherwise, clear the drive and do it properly! Always goes faster the
second time around :)

Sure of what? I'm confident using Linux' fdisk in partition table management,
until the drive is larger than 2TB, then it's a whole different ballgame ;)
