Filesystem corruption

I wanted to copy over a model.ini file holding ent while switch on to enable USB. Windows doesn't copy the file and reports filesystem corruption. Also I see some folders with garbled names. Is there anything to do to diagnose that?

I've recently experienced some problems with my TX and hardware files corrupting on the latest nightlies however, never once have I had a single problem running anything more stable than the latest batch of nightlies (where extensive development is happening, i.e. things are breaking and being fixed on an almost daily basis)...

First thing to do format and reload your file system, if it never happens again consider it a strange fluke, if it does happen after a format and reloading it may be something to look into more.

Put it this way; I haven't filed a bug report yet because I'm not sure it's a system-wide error, again likely just a strange fluke

As noted a number of times, the nightly development branch has been pretty stable for the last year or so. This changed drastically after the release of 5.0, with lots going on.
