Never trust spinning rust that refuses to reallocate sectors
(old indian proverb)
Playstation PS/3 is a small computer... that tries a lot not to look like a computer. I thought journalling is an old invention, but when I powered it off using power plug I was reminded that that's not the case. Result was 10 minute filesystem check, with note that it will take 4 (?!) hours if any problems are found. Ouch.
Anyway, it got me thinking. With 4 hours filesystem check time, it clearly has way bigger drive that it needs. 500GB... And hdd in my notebook refuses to reallocate bad sectors. (By some miracle, I did not really lose any data, and it was mostly behaving ok.) Refusing to finish tests is also not big problem, but it also made me nervous. Time to swap disks.
It turned out that swapping disk in PS/3 is not an easy process. You need additional disk to perform backup to, side cover is not really easy to remove, and box is dead and needs "software update" after you swap the disk. It took few hours total. (Come on, 18GB of save game data...?)
I got single transient error when trying to copy out the data.
So far so good.
