[atlas] V3 Probe: USB Flash Drive Filesystem Corrupted

Hi Michel,

the Probe ID is 25993.
There are so many cheap USB sticks with extremely low write speed, even USB 3.0 sticks.
What made me think that the sticks speed could cause the tag is, that my probe had it tagged for a long time, but still the probe did it's job. It was online, delivering results, etc.

I have replaced the broken USB stick with a fast one from Transcend 6 days ago. Since then, the tag did not appear again. I haven't checked for the blink patterns, sorry. If the Tag will appear again, i will try a different power supply and cable, as you suggested.

BR,
Simon

Funny enough, I actually used an old stick on one of my development V3 the other week and was surprised how slow the performance was (but the system did still work).

Can you tell the exact cause for the "Flash drive filesystem corrupted"-tag is? What triggers this?

If the unit receives just enough power to boot the base TP-Link, but not to power the USB stick this may trigger these problems. Would you be able to boot the unit with a different power supply (try 5W at the least or 10W), to see if this makes a difference?
