Are you using an SD card? Try replacing it, that may be the culprit. I'm saying that because:

1- Those seem to be storage-related issues

2- I've had that phone for a long time and the only issues I had were due to a HW failure in my SD (which I then replaced).

Also, when you insert a new SD choose the "portable storage" mode because in my experience it tends to be more reliable.
