Sansa e200 V2 / Keeps shutting down when copying

[Macguyver]

... I realize this hardware is old(er) but with Rockbox, 8gig inside and 16+ outside it's dandy. Just got a V2 and installed the latest build of Rockbox and of Sansa firmware.

I've got problems:

1. I've got two folders starting with ## off the root - can I delete?

2. More important, connected and talking nicely to the Win7 computer, when I start copying audio files to it, it freezes in about 2-4 minutes. Gotta hold the power button for about 2 minutes before if shuts off, then start over. It DOES however work if I boot into Sansa's UI.

I've another that has the same problem in that when copying OFF it it freezes.

In every other way they function dandy!


Any ideas?
