Entire harddrive not writable after install

[merajchhaya]

Hello

I am still new to Ubuntu. I recently installed 9.04 64-bit.

I have two hard drives in my laptop, the one where Ubuntu was installed wasn't partitioned, so I just installed it there, while the other is partitioned.

What happened is that the hard drive where I installed Ubuntu is not writable any more unless I have root permissions (I can't put my multimedia stuff there, etc, but the system can use it). So basically I have a 250GB drive doing absolutely nothing.

Is there any way, besides creating partitions and installing Ubuntu again, to make this drive somewhat writable?

If I installed Ubuntu again, how big should its dedicated partition be?

Thanks in advance!

Nevermind, now I understand that it's a security mechanism and that there are multimedia writable folders!
