PS1/2 Removing Data from PS2 HDD?

[goemon_guy]

I recently bought a PS2 HDD / Network adapter and all works well.

My main issue is, that I didn't realize that there were already installed game partitions on the HDD, and they're taking up a good 10GB approx. (The whole drive is only 40GB).

They're named as such,

PS.SCUS-97266.0001.FFXI (8GB on its own...)
etc.

So, I assume that they're game partitions.

Trying to remove them in uLaunchelf seemingly erases them, only to come back immediately after re-entering the HDDmanager.

So, I was wondering if there's any way to remove these (at the very least the FFXI one) to free up some space? I'd like to avoid formatting if possible, since I already put some games on it, and it would be tedious to copy them again.

Thanks for any assistance!

EDIT: Solved. If someone could close/delete this, that'd be great.
