[RIPE Atlas Ambassadors] Most of the probe down because of USB Stick read-only

Yes, already told that to all the host that host probe that distributed by me.
Getting feedback from one and two of them that the USB is read-only.

I just tested one of the dead probe, can be brought live by replacing
the USB disk.
Also realized that my own probe are using SanDisk and the dead probe
are using Verbatim.

Looking at the Philip report, looks like the Verbatim are more prone to error.

Further analysis, can we as ambassador find out which one are probe
that using Verbatim and which one are Sandisk?

Thank you
