Hi Guys
Really need your help on this. I recently upgraded from a AS3102T to a AS5202T. The disks in my AS3102T were being run as single disks configuration. I copied my photo library and data from my primary disk, say Disk1-4TB (primary) to Disk2-3TB. Then I took out both the Disks. In the new AS5202T, I put in the Disk1-4TB as primary and a new disk, Disk3-6TB as the secondary. This time I selected RAID1 configuration. Contrary to the Easy Migration Asustor said, when initialising the new Asustor AS5202T, it wiped my disk clean so I lost all the data on Disk1-4TB. I accepted it because I had saved everything to Disk2-3TB.
I then bought a SATA to USB3 connector for Disk2-3TB to use it as an external disk on the NAS to transfer the data to the new NAS. I went to File Explorer on the NAS and was shocked to note that it says the Disk2-3TB disk only has some 256MB of data on it and there are some weird locked files and folders. I had saved nearly 1.5TB of data on it. I'm so upset as all my photos etc were on it. Any idea how I can access/recover this?? I dont even know what file system this is as it did not work when I connected to my windows laptop.
I'm going to try using Disk2-3TB again as a secondary disk in the old AS3102T which I still have and putting some other new disk in as primary. The problem is that I will have to initialise the NAS and it may wipe it out the disks again. I dont know what to do. Asustor technical help still has not gotten back to me. If anyone can help I would be grateful. Am really stressed.

Re: HELP!! - Cant access my disk after upgrading to new Asustor NAS
Hi,
I am in travel and can't have time to analyse the problem but :
... STOP using your backup disk in NAS ... use it only as external , size you see is for some specific partition directly usable, the DATA are in a GPT partition configured as Raid 1 EVEN you are in single disk
... ... so if your A.D.M. used ext4 ... you must remount the Raid to access your data ... if A.D.M. use Btrfs it's a little more complex.
... Raid1 is to use 2 disks of the SAME size (or biggest lost space) and when you have a disk ALREADY formatted for NAS you MUST start with the single disk ... and AFTER, when all run as well, you can use the upgrade/migration to move from single to Raid1
So the first and unique target is to verify that your data are available in the backup ... so better is to use a live-USB Linux with Raid tools (mdadm) to test and verify
Windows can also be used but it's more complex and risky.
Try to ask to a friend with Linux knowledge .. or call again again and again the support.
Philippe.

Re: HELP!! - Cant access my disk after upgrading to new Asustor NAS
Hi Philippe,
Thanks for your advice. I've stopped using the disk. Yes the ADM used ext4. I downloaded a software to remount RAID and will try doing if after the Asustor tech team does a remote login to check the problem.
I hope Asustor can change the detail on its website to talk about Starting with Single and then using the upgrade/migration function to add another disk. They just say go ahead and plug them in and you wont lose any data. In reality, if it is a higher version of Asustor NAS, it wipes the disk while reinitialising it.
I will update as soon as Asustor tech desk has done their job. Thank you
Neil

Hi Philippe
The Asustor helpdesk manually accessed the disk and all its contents were there. Quite surprising as using the Linux system to check, it said no contents and 0 bytes. But it was all there. So I guess there was some encryption. So thankful!
