I did a quick search on these forums but couldn't find an answer to my problem so, here's the thing:
I have a 60GB PS3 and ran out of disk space. Went to system information and it said I was using 45 GB of 46 available. I get that the PS3 reserves a percentage of the disk and that a 60 GB disk doesn't have actually 60 GB because of the conversion method used between bytes and gigabytes and stuff, so I see no problem with this.
I backed up my data to an external device and installed a new 500GB disk on my PS3. The PS3 immediately asked me to format the drive and so I did. Then I used the restore utility to copy the backed up data to the new disk.
Here is were it starts to get weird...
I went to system information and it said that I had 366GB free of 465GB available. Ok, I can understand the 465GB part because of the reserved percentage, what I don't get is how the hell am I using 100GB of space when I just restored the data from a 60GB drive??? I mean, if I was using 45GB on the old disk, how is it possible that after restoring the backup, the same data now uses twice as much space??
I would really appreciate so enlightenment on this subject.
