Hello,

your hda4 isn't a partition you can format with an fs.
A harddrive could have only 4 primary partitions.
So if you need more you must use an extended one like your hda4
in this partition you can build many more I think something like 63
(I'm not sure) like your hda5. You at the moment could create new
partitions form block 8102 to 9472 into hda4 to get more space in a new
partition.
The other way is to grow up your hda5, but (please forgive me) it isn't
nothing for your skill.

And again!!!
Don't forget backup before changing any disk-layout !!!!!

Regards

Falko
