Which error do you get? The maximum count or the unchecked fs?

The unchecked FS, the "I've been a bad boy" error.

Which partition were you getting that error on?

I don't remember which it was, I just remember having gotten the error in the past.

But let's say, hypothetically, that I'd used hijack for one thing and the player software for the other thing (again, don't remember which).

Do you think there might be a chance that there would become a desynchronization? Such that when I tell the player software to mount RO, it either doesn't do it because it doesn't know Hijack has set one or both to RW, or it thinks it already did so when it exited (but it only ends up doing so on the one because it only thinks it needs to do one)?
