the question is more how and where, in, with what. so when you finished with whatever you doing on your pc(deleting files doesn't sound good). it might be good to have the

cat /proc/mounts

output so that the "guessing" stops and instead "know" what we have. so long as it is still possible to mount the thing considdering the errors you talking about.

you didn't pull out Mydocs that we know for sure but for the rest .... i want to see whats up with it.
btw /proc/mounts shows also if something of the kind retsaw mentioned is going on. facts.
