I had no idea that Brennan boxes had a Pi in before now!

Brennan solved the problem.


I run a RPi as a music player with an external DAC. It runs Runaudio
(http://www.runeaudio.com/), and generally works well, but with
previous Linux images (volumio, for example) I had problems with
corrupt cards, especially after an unexpected power cycle. I make a
point of using decent quality SD cards, but it has been pointed out to
me that industrial grade cards may last better:

I've not yet tried this as the current one with Runeaudio has lasted
over a year, even surviving a dodgy PSU that at times caused a boot
failure.

Well, I have spent all afternoon on the phone to the friend and looking
into his Brennan. The SD card and main HD still say they were
improperly unmounted and may be corrupt. The main drive gives an error
message about an invalid cluster chain.

We spent some time looking at how to power the device on and off safely,
which is not terribly clear. We got an external CD drive to rip, but the
CD name failed to appear, so when it had finished (in about 2/3s the
time of the internal drive) we couldn't find it on the HD. It turns out
that he has been ejecting 'unnamed' CD's during the standard ripping
process because of the black hole they fall into. We assume this doesn't
affect the mounting of any drives. Many of his (and my!) CD's don't seem
to appear in any online databases.

He is hopefully now going to raise these questions in the manufacturer's
forum.

Thanks to everyone for the help, discussion and ideas.
