Mine was also because of the GTA IV issue, locked up, frooze and the drive stopped working, that is the one right?
In Sweden the general view is that it is up to the consumer to back up data. Regarding copy protected stuff you can back it up via system back up but not by copying it manually.
Also I didn't get my money back today, surprise surprise.
My PS3 worked perfectly other than the random freezing from GTA IV. Drive was fine and everything. I'm not entirely sure why they took it back, but I won't complain. I didn't get my original console back, but I'm not sure if it's new or refurbed. Regardless, I lost my Rock Band data because of it =/ Got everything else back though! I'm glad I manually backed up all my saves because the Backup Restore didn't do jack squat.
