General NAS-Central Forums

Hi Everyone,

A few days ago I installed a 2TB Western Digital Green, on my NSA210 (Firmrware 4.41).
I copied my files from my PC to the NSA210 and everything was fine until...

Yesterday morning I noticed that the HDD Light is Red. I assumed that if it was too many hours idle, maybe the HDD would stop.
I did a restart to the NSA210 and it worked correctly.
This morning again I saw a red HDD light. I did a restart but since then, it keeps red, and the in the administration page it show as "down".

Is it a hard disk problem, or something else?

Thanks in advance!

Hello again,
I removed the disk from the NSA and check it with Disk Sentinel on my PC.
Disk Sentinel showed that it's OK.
The problem is that I can't transfer my files to another drive, because although the BIOS is detecting the disk, in the Windows when I check the storage, I see the disk, but I can't do any action. I see two "freezed" partitions.

What should I do... I don't want to format the Hard Disk but I can't access it!

Any ideas? I don't know how to access the contain of the HD through WIN8 so to take a backup of the HD and the format it again...
plz help!

These are the result from the Scan Repair...any ideas?
Please help...

It's funny although that I'm asking for help for 1 day, and no one can help my... :/

Update:

After a lot of search, I found that the disk is formated in kinda Linux Raid.
I load Ubuntu on my PC and I managed to read the 1st partition (Ext2), but I can't access the 2 which is labeled Linux Raid Member.
Although I remeber I set up the NSA210 under JBOD system, why is now under Raid?
and how can I have access to this Raid?

Still is weird why although this forum has a lot of knowledge to these matters, no one can give me a single clue...

Thanks.

This is almost for sure a hardware error. Try a diagnostic tool from the disk vendor.
The data partition on a ZyXEL is always a raid array. In your case probably a single disk raid1 array.By assembling it. Open a terminal, and find out the device node of the data partition:It's probably sdb2. The size is given in 'blocks', which are kB.

When you have located the partition, assemble the array:When this succeeds, you can try to mount /dev/md0. (Which will possibly fail due to that filesystem error).
Maybe you have to install mdadm first:
