QNAP not booting and recovering data from hard drive

I have a QNAP NAS with 2 drive bays. It was working fine , both drives mirrored,

When I had the hard drives in the QNAP failed to boot it self fully. it just displayed a load of errors on the screen.

So I pulled out both of the hard drives and booted the QNAP. Now its saying this in the web browser:


Hard Drive Missing

Install and format at least one hard drive before using the NAS. A hard drive can be inserted to an empty disk bay without turning off the NAS. For the hard disk compatibility list, please visit http://www.qnap.com/go/compatibility_hdd35.html

Note: All the drive data will be cleared upon hard drive initialization.

Please make sure the hard drive(s) are installed correctly and the hard drive cable(s) are securely connected.



The problem is I want to boot into the QNAP, put the hard disks in , and then maybe it will be able to read at least some of the data on the drives. I do not want to re-initialize drives or reformat them.

I want to maybe correct errors from the GUI which i believe are on one of the disks.

As explained earlier, when I left the drives in there (for 24hrs) the QNAP failed to boot into the GUI. Is there a way to at least check these drives? surely they both havent failed on me? Whats the point of a mirror if the QNAP wont even boot into the GUI with the hard drives in?  Is there another way where I can at least check both disks for read errors maybe using a software which QNAP have released as I used QNAPS GUI to encrypt them. You cant just plug this into external drive to check them - you have to put the encryption password in to unlock them

Did it display errors with one of the 2 drives? If so, this could mean that the raid set has failed. Usually you just replace the defective drive then to let the QNAP rebuild the mirror by itself.

Can you boot the QNAP with just one drive in the system? To do this, switch it off, place one drive and try booting it. If that fails, swith off again and try the other drive, same procedure.

Agree with @gerwinjansen...but also what were these 'errors'? They will give details of what is wrong...can't understand why you pulled 2 drives from the system

When you say you 'encrypted' them - you mean using a plugin from the QNAP frontend? That will make life harder for recovery I think...which model of QNAP do you have exactly?
