Flashing QNAP with disks removed
Q: I pulled the disks out of NAS QNAP to update firmware and then connected them back, but the NAS does not see nor does it initialize them. What should I do?
A: Try to pull the disks out once again, return to the old firmware, and then put the disks back. If it works, try to update firmware without removing the disks. One part of the operating system inside QNAP is stored in the built-in NAS memory while the second part is on disks themselves. Mismatch between these two parts leads to NAS refusal to work with disks.
