Hi raspdealer,
I see two problems here:
- you havent specified the USB device filesystem used in the fstab entry
- instead using the partion’s device file use the block id instead; the block id is always unique whereas the device file can change depending on the number of USB devices and result of critical races while detection.
Just an example, how the /etc/fstab entry looks at my system:
UUID=3a07a91e-7201-4e27-979c-7ea7cdbee497 /mnt/hdd1 ext4 rw,nosuid,nodev,uhelper=udisks 0 0
The UUID you get with the command blkid.
