This is currently the only showstopper for this project.
The following script (test.sh) is used to test it.
#!/bin/sh
echo "FORMAT:"
/root/format_usbdisk.sh sd0
echo "MOUNT directly after format: "+`date`
mount_ffs /dev/sd0a /mnt/matteus
time ls -l /mnt/matteus
sleep 3600
echo "MOUNT after 1 hour: "+`date`
time ls -l /mnt/matteus
sleep 7200
echo "MOUNT after 3 hour: "+`date`
time ls -l /mnt/matteus
sleep 14400
echo "MOUNT after 7 seconds: "+`date`
time ls -l /mnt/matteusI also make use of format_usbdisk.sh.

If we should build a OpenNAS system with a internal HDD I think the following components could be suitable.
The system may also work as a very capable firewall.
Total: 175 euro
An internal 3.5 SATA HDD (e.g. 1-2 TB) is needed to complete the system.
