cRIO 9033 makes USB Stick read-only

[EWiebe]

Hello all,

I have a problem with our cRIO 9033: it makes the adapted USB Stick (means USB Flash) sometimes read-only:
It is a cRIO 9033 and has an inserted USB stick / flash. The problem is that this USB stick (with FAT32) gets all few days / weeks / months unusable.
In the logs I can see then:
kernel: FAT-fs (sdc1): error, fat_free_clusters: deleting FAT entry beyond EOF
And after this entry the file system is set to read-only.
Restart of the cRIO does not help !!!
After restart same issue: Filesystem is set to read-only
Only this helps: unmount and re-format the USB stick from within cRIO (which is mounted on /dev/sdc1 😞
umount -l /dev/sdc1
mkfs -t vfat -F 32 /dev/sdc1
If I execute this line before reformatting:
dosfsck -a /dev/sdc1
Then I see the results:

This all happens in our production line.
Perhaps I have the wrong USB Stick / USB Flash ???
We already changed the USB Flash in the past but this issue happened again.
Which one (USB Flash) would you suggest?
Thanks to all who could help.

Are you trying to use a USB stick to store data?

Why don't you use an SD card? There is a list of tested CompactRIO Industrial SD Card Accessories
