RAID 0 is an array quite risky. Only one drive die then kill your data all! I have replied you in another post, you need to make sure if your drive is well sat on its position, or if it is faulty.

I opened another thread on this forum. At this moment I have a RAID 0 configuration so an emergency backup is very important.

I have used Samba from the PC to manually backup the shares either to a drive connected to the PC or connected to the NAS' USB port. It's not very fast, but I get to select exactly what I want backed up. Then I unmount the backup and secure it in a fire-proof vault. Having the backup drive connected full time for automatic backups leaves your backup susceptible to theft, fire, electrical damage and other corruption. Best to have an offline backup even if it goes out of date a bit.

Thanks for your reply, i’ve done the same thing, and til now it works very well. When the system unmount the usb drive, after few minutes it goes on standby and poweroff all moving parts.
