I've been fighting with my Iomega Storcenter ix2-200 for three days now. I've been through countless forums and the NAS has been out of warranty for a couple years now.

This is the second time in four years I have had an issue with the NAS. The first time it was under warranty and it turned out that one of two drives was bad. After replacing the bad drive, everything worked as expected.



However, my current problem is that I cannot access the information on the NAS. I can get to the web interface, but I cannot see any information on the system. I noticed the problem when Windows 7 showed the drive crossed out in Windows Explorer as though the location no longer existed.

I began troubleshooting by restarting the NAS through the web interface. When it came back up, the same problem persisted--access to the web interface, but no data.

The next step was to power down and pull one drive out and restart the NAS. I did this for both drives and the problem remained.

After that, I powered down and pulled both drives out. I connected each to an external hard drive base. I then plugged that into the computer and while the base registered, neither hard drive showed up.

I am running the RAID setting (is it 0 or 1) that mirrors the data between two drives, so if one dies, my information remains. I hope both did not die at the same time on me this time.

During my troubleshooting attempts above, when both drives were installed in the NAS, I went to the Dashboard tab on the web interface and saw that "reconstruction" was taking place. I let it run overnight and came back to see that the reconstruction was back at 3%, where when the night before it was at 20%. Since then, I have noticed that it gets to around 30% or so and then starts over. It has been stuck in that cycle all day today.



Currently, I replaced one hard drive with one from another manufacturer (RPMs are still 7,200 and the size of both are 1TB). I know it is more advisable to use the same manufacturer too, but I only had a Hitachi laying around whereas the NAS drives are Seagate.

The "reconstruction" is now at 17%. The message still includes, "2 new drives with existing data have been added to your Iomega StorCenter device." but the Hitachi is new and just out of the package. My hope is that if reconstruction keeps cycling, I might be able to power down the NAS, remove the new drive, and see if there is anything on it.

I don't know where to go after this, or if I'll have to send one or both of my drives to some place that charges a lot of money to repair them. Does anyone have any opinions or knowledge of this disaster of a NAS?

Thank you,
JC

If it's a mirror, then it should be enough to image one or other of the drives, sector by sector (unless there is something strange about this NAS). You could use ddrescue (freeware) for this. Ddrescue maintains a log, so if there are damaged sectors on one member of the RAID, then these could be retrieved from the other member. It would probably be advisable to create separate clones of each drive. though. Then you could merge them onto a third clone, just to be safe.

Hopefully Ubuntu Live or Linux Reader for Windows will be able to see your data.

By disabling features such as read retries, you can improve your chances for data recovery.

Do you need data from that NAS or you want to continue to use this enclosure?
If you need data you can follow fzabkar advice.
In other case you need to replace both hard drives in NAS enclosure.

is drive shown in Drive Manager or Device Manager under Windows.
There are probably Seagate ST1000DMxxx drives installed in NAS

One or both drives probably have bad sectors. The most worst thing could happend with Raid1 when one drive failed long ago and you are making migration (rebuild) using that "old" drive .
