seems my USB-Stick is somehow broken after about 4 Month only
As I couldn't get the most recommended Patriot I go with the Super-Talent Pico 4GB.
Anyway suddenly I see my metehub was not generating any pics anymore but still sending data to APRS. I checked the Web interface and saw the error message that the config file is read only.
I could download it but I wasn't able to connect the share drive to save historical data. As the weatherstation is in an other location I decided to reload, which seems wasn't a good idea to do, since then my meteohub is dead.
As reboot won't work I connected the USB stick to a PC started with a linux live CD. But can't access the USB stick, on any try to mount, fsck, mkfs -n, ... I get an read-only or other error message. As well a dd to save data in some way fails with a i/o error.
See some of the error messages below.
Any hint how to get data saved, if not is it worth to rebuild the USB-Stick or just throw it away and use a new one, if so what is recommended if the best choice isn't available anymore and the second best fail after 4 month only. Is there a good way to go with a USB-Cardreader and a good CF- or SD-Card.
regards
