Copy anything important off of it, in order of priority.
If there's one thing awesome about flash storage, is they can make it fail in a way where you can still copy almost everything from it, even if at extremely slow speeds. When a HDD fails, you're shit out of luck.
@Awoo
Any chance it's just an issue of a lot of random reads/writes or needing a defrag?
This is a pretty old portable. I've had it for quite a few years now.
