just before everyone gets too paranoid about the new firmware - I updated, no problems, after the regular restart it started compiling the library - and everything went perfect. All files and metadata intact…
You are a lucky then. Selected automatic update last night and now my unit does not recognise the internal hard drive and I fear all my kids films that I had carefully installed are now all lost.
As the internal drive is not visible after numerous re-sets (hardware and software) I suspect it will require another firmware change to correct.
No problems here either.
