TOS 7.0.0616 may crash your F5-422 immediately after the update is completed
and reboot.

Your NAS may not be able to boot up and produce constant beeping noise.

I've also received the below notification message to my email.

"The array in storage pool 1 has been corrupted due to missing required disks! Please check if any disk in your array has failed or been disconnected. For data security, promptly reinsert all required disks and attempt to mount the storage pool."

I also saw someone else with older model NAS is having the same issue as well.
eg; F5-221

We need to check this issue remotely. Please visit the link and schedule an appointment with online customer service for remote assistance:

FYI My F2-221 has been updated and is running normally.

I'm having the same problem; it doesn't recognize the drives in SATA ports 3, 4, and 5 (F5-221), and the update was version 7.0.0706.

Help, please! I have four drives installed...
