Hello, i've got a problem with my external HDD.

I have 500 GB Seagate expansion which i use to play Jailbreak Game. The problem is like this :

First, the remaining size of the HDD is 54 GB. I checked it via PC, PS3 System information and also from the Manager (Gaia / Open Manager). They matched each other (54GB).

And then i copy 3 games (about 53GB), which now the remaining size of my HDD should be 1GB. I Checked it via PC. It display 1GB.

But when i checked it via PS3 System Information and also from the manager, it still display 54 GB remaining, which means "my HDD size didn't decrease even after i installed those 3 games"

Windows (PC) display 1 GB left, PS3 and the manager display 54 GB left.

Is there any problem with my HDD ?

Note : I can play those 3 new games....

Thank you
