Hi to everyone,
I’d ended up in this post because I have a dead IOMEGA IX2-NG (The 2 x 1TB HDD version).
This is what it happened and what I’d tried till the moment.
Last week the NAS started acting strange. Very very slow reads/writes and the web interface was almost unusable until last Monday the red light was on and my IX2 only responded to pings but nothing else…
I took out the disk on bay 2 out of the IX2 and woops it booted again, so I recovered the data.
Then I followed instructions that I found at lenovo’s site saying that to replace an HDD you only had to clean the disk and insert it to the IX2 and magic should happen…
I did that with diskpart, as instructed, I inserted the cleaned HDD into the IX2 (Not a new one, it was the corrupted one), powered it up and magic did not happened! The red light turned on again and it never went off!
I know what you are thinking… may be I didn’t leave it enough time to mirror the other HDD… I knew it could take some time so I leave it for 2 days untouched…
At this point I started testing… no disk, 1 disk, 2 disks, inverted them, all combinations possible with no luck… sometimes it responded to pings but no Web GUI.
Now I am with an untouched HDD and a clean one (the one it was corrupted at first) but none of them boots the IX2.
Both disk are fine. I checked with Crystal Disk Info and it says it’s all OK.
On the disk from bay 1 I can see partitions from linux.
And before wiping the HDD from bay 2 with diskpart, I created a NTFS partition and wrote around 500GB of data with no errors… so I know its operating fine.
Now I want to start fresh with the wiped disk (from bay 2).
I follower all steps that you guys had tried with no success.
What I did:
I downloaded the unencrypted firmware (tried with v3 and v4), unpacked it.
Wrote zImage and initrd with dd if=zImage of=/dev/sdX bs=512 seek=2048 and dd if=initrd of=/dev/sdX bs=512 seek=8192 commands from linux with success (the disk was connected to the PC with S-ATA cable, not with USB to S-ATA).
Formatted a 2GB pen drive in FAT32 and copied into the folder /emctools/ix2-ng_images/ the file imager.tgz (I tried ix2-ng-4.0.2.9960-recovery and ix2-ng-4.1.114.33421-recovery and I can’t remember the version of 3.0 I used). I really don’t know what version was on the IX2 before this happened!
I plugged the USB flash and the HDD (on Bay 1) and powered on the IX2 while holding the power button. First the white light turns on and after 4 seconds both reds. After 15 seconds both redss turns off and the upper red appears and nothing else happens…
The USB Flash wasn’t read at any time because it has a light that turns on when accessed.
I tried with 3 different flash drives (32gb, 2GB and 8GB) all with same results…
Do I have to format the flash drive in a special way?
I tried all this processes with:
-the HDD totally cleaned
-only the GPT file system initialized
-with MBR too…
I don’t know what I’m missing!!! I don’t know how to make it read the USB Flash…
I also tried with reset but it just turn the white light and then the red.
I will appreciate all the help you can give me guys!!!
And sorry for my bad English… I’m from Argentina… I hope you can understand what I did.

So the disk which booted the IX2 after removing the other now doesn't work anymore? Did you do anything with that disk that you didn't tell here?

According to your tests both disks are fine, yet they don't work in your NAS anymore. I wonder if there is a power problem. The external power supply, or the internal DC/DC convertors might be broken, having not enough juice anymore to power both disks, and degrading further, not enough juice to power a single disk.

Not that I'm aware of. As long as Linux can mount it using the vfat driver it should be fine. But some people reported some usb sticks to fail. So maybe there is a hardware constraint, maybe a timing issue.

Your English is fine. At least the written variant.

Hi Mijzelf, thanks very much for answering!
I’ll try to give more information.

Exactly… don’t know why. It did work for some hours while I recovered my files. Not very fast I might add but it did the job. After that I wiped disk 2 (the bad one) and reinserted to the IX2 (Bay 2). That was the last time it booted.

I only plugged into a Windows PC via the S-ATA cable and opened Cristal Disk Info… I didn’t touch the filesystem and I didn’t plugged to the linux PC either.
From Paragon Hard Disk Manager (For Windows) I can see it has 3 partitions.

Good advice. I tested the power supply and it gives 12v but it might not be giving the amps that it needs. Today I’ll buy a new one to see if that is the problem. I'll report later.

Whats that? It can be changed?

Thanks a lot

The power supply supplies only 12V. The disk needs 12V and 5V. (And the CPU 3.3V or maybe even lower). A DC/DC convertor is some magic gizmo which can change one voltage in another.

Theoretically yes.

Hi Mijzelf,
I replaced the power supply for a new 12v 3a as suggested but same red light at boot… recovery still won't work either.
I’m thinking on buying the USB to LLC cable to see what’s happening at boot. Will it work with the IX2? I saw somewere a uboot screen displayed in a putty enviroment or something similar.
Another suggestion you have in mind?
Thanks!

I don't know what 'LLC' means here, but I guess it is 3.3V TTL serial. It's a good idea, and actually the only way to get more info on what's happening.

And yes, it will work. Here is the pinning.

I meant TTL! sorry. It would work if it's 5v and 3.3v? or it has to be only 3.3v?
Thanks!

The board has a 3.3V serial port. (Almost all modern SoC's have a 3.3V serial port. Although I have also seen 2.8V). AFAIK a 5V also works, although for low levels of 3.3V the 5V might not be able to see the difference between a 0 and a 1. In which case it doesn't work, of course.

I have a IX2-DL with solid blue LED and blinking once a second white LED, after replacing the only HDD that crashed in the unit. The HDD was "clean" according to "diskpart" instructions. But that is it. I don't have any linux and do not know how to operate linux, to create the flash pendrive files to boot the IX2 from USB. It would be an angel gift to have the file that needs to be in the pendrive for download somewhere at the net, and some other application to run on Windows that would "format/write" the files into the pendrive. I don't think it is nothing wrong to have it available. Iomega/LeNovo should have it available to help customers with this problem. I can't access the unit via html page, only ping the IP works.

Thank you for any single help.

The desperate user from "LeNovo/Iomega support that does not work".
