"Re-initialize" N2050 question
#1
Hi:

I have a N2050 which was initialized with RAID 0 (stripe) with 2x 500GB WD harddrives. I have been using it for many years now without any problems. Today I took the hard drives out and put them aside and added two different harddrives to test RAID 1 (mirror). After testing I re-initialized the two drives with RAID 0 again so that the device is setup as RAID 0 again before I put the original two drives back in the exact slots they were.

When I started the device up again the HDD Power and Activity LED's just keep blinking. According to the manual that means the device is not initialized or initializing. It has been an hour and still flashing.

I am worried I have lost the data on it as it was striped but I have not pressed the init button while the two original drives have been in the device.

Can anybody assist me how to fix this please?

Thanks.

Just an update for others that might encounter the same problem in the future. I have managed to get all my data back - as long as you don't "re-initialize" the disks. The data is still on the disk and it is just the metadata that has been lost, so I was able to recover the RAID array with the help of some software.

I removed the two disk from the device and connected them directly to SATA connectors of the PC. I then installed "ReclaiMe Free RAID Recovery" software and was able to recover the RAID 0 and write the data to a new drive. Below are some useful links that helped me out.

Thanks for this great help Venterbg. I'd also like to introduce Stellar Phoenix RAID Recovery which helps user in rebuilding corrupt or damaged RAID arrays without taking any extra inputs. The tool itself is capable to determine the disk order and helps you run smooth scanning and later, recover all of your precious files and documents.

Currently, this program supports RAID 0, 1, 5, 6 and 10 architecture.
