Hallo,
just tried the latest revision and did some test_disk runs on it.
At a first glance it looks really good. Seems it was really the voltage scaling causing these errors.
But i keep an eye on it. Thanks.
Edit:
Unfortunatly this was not the solution. Nothing has really changed. The same errors like before. (Yes, I formated the SD before it.)

I'm still getting uSD lockups, even without voltage scaling. If I put my 2gb SanDisk card into my e200v2 while it's running, it will lockup when I try to open the file browser. If I boot while the card is in, it hangs on the boot screen.

What was the last revision the card worked with?
If you post in this very development thread, then please don't just post bug reports or problems. Help development or stop posting here.

@Hillshum:
Have you tried reformatting the card? I have had what sounds like the same problem and formatting the card made it work again. This was pre voltage-scaling times i'm talking about now.
re: voltage scaling
I have been able to duplicate the condition described by MC2739 regarding the microsd card by taking the voltage down to 1.05v in my e280v2 but other than that I have no other progress to report but I'm still looking...

I wonder if the voltage scaling for the CPU is affecting the uSD card voltage also. That might explain why some cards seem more sensitive than others to the corruption. Unfortunately, I am not yet familiar enough with this platform to confirm it, and I cannot afford to destroy my only fuze right now. Maybe I can find a uSD interface adapter to put a VM on, anyone know of such a beast?
Also, I have noticed that the USB code does not differentiate between power and data connections, if I apply a charging voltage only, it reboots immediately into the Sansa FW. I am also concerned that the fs is not being committed and closed cleanly when this happens. Does rockbox use a sync or async filesystem?
