Not really, unless you try reflowing the PS3. I didn't have too much luck when I tried it (PS3 only booted for about 20 minutes) but I also didn't use a proper heat gun either.
The PS3 also uses some proprietary file system on the hard drive that isn't recognized when you connect it to a computer. Not to mention the data is locked to the console it was formatted on, so you can't even pop the drive into a working PS3 to get data off.
If your friend REALLY wants to get those saves off, the only option would be to try a reflow and back up the data when the system boots again. I wouldn't use the system after reflowing as it's bound to need it again. It's not a permanent fix, unfortunately.
I'm surprised no one mentioned this already but SAVE YOUR GAME AND SAVE A LOT.
ME1 particularly has no check-pointing whatsoever and even if you have auto-save on, the points at which it does so is too far apart for comfort. Even on Normal I died enough where the infrequent auto-saves ticked me off a bit.
ME2 does a MUCH better job at this though. My first time through I never did a hard save as it was super generous with the auto-saves.
My plan currently is to have every single member of my team die in the mission, but still have Shepard live of course. I am not even sure if it is possible to have everyone die but I guess I will find out soon enough.
In case you really want to find out yourself, I'll spoiler tag this, but...
