Iomega ix4-200d Four drives in RAID 5 Lost Data

Hi,
I've Iomega StorCenter ix4-200d with firmware version 2.1.46.30093. The unit has four 1TB drives setup as RAID 5.
I've been having intermittent issues with drive 4 and IOmega device has been automatically reconstructing the protection in last few weeks. Recently drive 1 showed similar issue and now the whole data became invisible.
After Login to the device I see this message:
4 new drives with existing data have been added to your Iomega StorCenter device.
The Iomega StorCenter device failed and some data loss may have occurred.
On the Disks page, I see the four disk and If I hover over one of the disk it display this pop help message:
Disk has been replaced with a disk containing data from another system.
On one of the page I got this message:
Disk Overwite Authorization:
A disk with existing data has been inserted.
Note that using this disk will permanently destroy all of its previous contents.
Check this box to authorize overwriting the disk.
I have not done the overwriting to avoid any data loss. The unit is out of warranty and I need data recovery.
So far I've found these options online. Just would like to know the your experience, data recovery success and $$ amount you paid for the tool / service for recovery.

Please advice.

 Hello svfm
As mentioned in another thread, UFS Explorer has been fairly successful, however I have not seen quite as much results from other applications.   iRecover would be the next recommended option other than contacting a data recovery provider that can work with RAID systems.

  • Removing our AD server / disabling security on ix4-200d

    My organization is in the process of decommisioning our Windows Server 2003 and moving to complete reliance upon our iomega ix4-200d for our file serving solution.
    My understanding is that disalbing AD on the iomega device will remove the existing users and shares that have been synchronized from our Active Directory.
    I'm looking for suggestions about how to recreate the existing AD user accounts once the ix4 is in workgroup mode while causing a minimum amount of disruption to the office -- especially since I obviously don't know the passwords of the existing AD user accounts?

    swgarland wrote:
    Without getting into a discussion of why you would want to remove AD from a network, on the NAS box, you'll need to create local accounts (you won't have a domain anymore).  Then create groups etc, just like you had before and apply the correct rights.  You'll have duplicate accounts for a time period (domain and local).
    PV: Basically, we've retired our Windows Server 2003 in favor of the NAS box and when I finally pull the plug on the Windows box our AD will go away.
    I would create all the accounts FIRST including a new NAS admin account.  Then login to the NAS with the local admin to verify it works BEFORE you disable AD integration.  Once you disable the AD integration, all the domain accounts and groups disappear, and therefore won't work.
    PV:  That's kind of what I gathered, I was just hoping someone else had gone through this before and had suggestions for duplicating the accounts. I guess I will set the accounts up ahead of time and try to figure out a way to make people change the default password I give them.
    Looking at the "Users and Groups" admin applet, however it's not clear to me how to create local users and groups when AD is active. I don't see any interface to add users or groups, only links to "import users and groups from Active Directory" and to "synchronize with Active Directory"?

  • Iomega StorCenter ix4-200d iSCSI performance

    Hi there, just looking for some help here, we have an Iomega StorCenter ix4-200d device that was not in use and I tried to make a drive for storing media files and moving them from the file server. I have created an iSCSI disk and connected to a Windows 2008R2 using an iSCSI Initiator, the Iomega box comes with two network interfaces that were previously bonded, the connection was quick and easy to setup, the problem that I am having is performance. When transferring small file/s the transfer is quick and effective, but if the file/s pass more than 1GB windows explorer crashes and the OS get frozen, I have been monitoring the disk use and is horribly high when transferring those files, taking more than 10min for a 1.5GB to transfer, the LAN is 1GB speed. I read about creating specific VLANS only for iSCSI transfers, but we did not have that before and the drive was previously used as iSCSI backup solution, before another solution now in place replaced it Any help or thoughts are more than welcome Juan

    GUS_Lenovo, Really helpful your coment, please can someone else let us know if it is having this problem. The setup is very simple a VMware ESXi 5.5 virtual machine, OS 2008R2, connected using passtrough native windows iSCSI initiator to an external Iomega StorCenter ix4-200d drive. I disconnected the target from the troubled server and connected the iSCSI disk to a test server, same setup VMware 2008R2 connected to the pysical iSCSI uing the windows native initiator, no roles on it. I double checked that only the test server was connected into it, same symptom, transfers files up to 500MB are quick and effective, if the file/s to transfer pass 1GB or more the transfer halts and the explorer process on the VM crashes, not very effective for now. Bandwith?? any help very much appreciated

  • IX4-300D how do I import a new drive into RAID 5 Array?

    I already had a 3 x 2TB RAID 5 array, added new forth drive (same 2TB drive model) and let it auto format, which completed OK, but when I look at Status in Admin I see "Unallocated 1.8TB". This tells me the drive was formated but not imported into the Array.
    Looking at Drive Management Page it shows all four drives installed but offers no actions, you cannot even select a drive to display or take action on.
    Going into Settings only shows the settings I used to create the RAID 5 initially, no other options. I would expect a workflow of right click new drive and select to import into RAID 5.
    Looking in the help section no detail on RAID only a basic comment on what RAID is.
    Something badly missing here. Is there some info I have missed?
    Peter

     Hello 2Old2Slow
    I highly recommend that you do make plans to backup your data from the unit before attempting to expand the RAID just in case something goes wrong in the process.  
    When trying to expand an existing RAID 5 from 3 to 4 disks, you can use the "add disks to storage system" option that is located in Drive Management>Settings.  This option will become available after a new drive is added to the empty drive and the unit is powered back on.  It may need to overwrite the new disk, it will indicate which disk is being overwritten by marking the new drive with green stripes.  If you are being asked to overwrite data but none of the disks show green stripes, please stop and backup first as proceeding will most likely result in all disks being overwritten.

  • User quota update bug on Iomega StorCenter ix4-200d - 2.1.42.189​67

    Hi everyone,
    my device is Iomega StorCenter ix4-200d running firmware version 2.1.42.18967
    Last week user X on my device exceeded his personal folder's default quota (2 GB): I told him to move exceeding data away from the storage device and he did so.
    Now he only has 300 MB under his folder, but the the device's web interface is still complaining about userX using 50 GB of space and therefore exceeding his quota. Furthermore, user X is not allowed to put more data into his personal folder, even if only stores 300 MB of data...
    I tried the following solutions:
    reboot the device
    disabled quota on user X's personal folder and then re-enable it again
    but none worked. How can I fix the issue?
    Any help/hint would be appreciated. Thanks in advance

    Hello sanzso
    I highly recommend you contact LenovoEMC PX12 support in your region regarding this issue. 
    a quick suggestions though.  If media server is enabled, in some situations there can be an issue causing a data usage mis-match.  Usually this would only show the  "others" listing to show as having a strange usage level.
    To correct this, media server would need to be turned off, copy the share data to a new share or external storage device, delete the existing share(s) then restore the data to the new share(s).

  • Can you run RAID 5 + Hot Spare on ix4-200d, or just RAID 5?

    Solved!
    Go to Solution.

    Hello trevorsem
    The ix4-200d would only be able to do RAID 5.  Hot spare would not be an option.  You could technically use only 3 disks in the RAID 5, but it would not be using the unit to it's best ability.
    PX class devices can use hot spares with RAID 1, 5, 6, and 10

  • Iomega StorCenter ix4-200d replace all disks

    REPLACED DISKS: 4 Hard Drive SEAGATE 1 TB with code ST31000520AS.
    Before the replacement, had carried out the firmware upgrade for CC38 as executable: DriveFWUpdater-1.8.exe
    Successfully finalized.
    After the replacement of 4 discs, the procedure would make a boot by USB to reinstall the OS, right?
    But when holding the reset for more than 60 seconds, does not appear on the LCD panel USB image >> Network, does not find the boot from USB.
    Is there any other procedure?
    Thanks.
    Solved!
    Go to Solution.

    Hello estaile
    The "DriveFWUpdater-1.8.exe" utility is just for updating the Seagate firmware to cc38 in the ix4-200d / ix4-200d CE.
    to replace all the disks you would need to follow the disk upgrade guide here.  Basically if you still have at least one original disk with the Lifeline OS firmware, then you can boot the unit with that disk and 1-3 blank disks, after booting the unit will copy the firmware over.  if the web interface requests overwrite,  allow the overwrite.  after that has finished you can power down, install the 4th disk and boot up the unit.  the previously installed disk(s) would then be able to copy the firmware over to the last disk.
    If you do not have any original disks with the firmware intact, it will limit your options as some of the legacy firmware imagers are no longer available.  I recommend contacting LenovoEMC support in your region at that point to see what options might be available.

    nagamani,
    The only option is to flash it, which I understood that you had already tried as part of that set of instructions you posted is for the imager.
    If I am mistaken, you can contact support and request the imager here:
    https://lenovo-na-en.custhelp.com/app/ask/
    I cannot release the imager on these forums.

  • What harddrives are approved for use with ix4-200d?

    Hi,
    I found an article on the Lenovo site for the process of swapping out all 4 hard drives in an ix4-200d, but what I can't find is an article showing the list of approved/recommended hard drives for use with the ix4-200d.  Can anyone point me to such an article?
    My ix4-200d has a 4x500GB configuration (Seagate ST3500412AS drives).  I'd like to swap them for either 2TB or 3TB drives, so I can have one place to store all my raw video, which right now is spread out over three different devices.  Also, if you have any advice or gotchas to look out for when I swap out the drives, I'd love to hear you on that matter.
    Thanks,
    William

    Hello vitorpereira
    In regards to the ix4-200d and ix4-200d CE, Iomega/LenovoEMC never created an approved list of drives.  When a disk failure occured the disk should be replacing with a matching drive if at all possible.  
    When it is not possible to use a matching disk model, a similar disk should be used.  This would be a disk with the same manufacturer, capacity and rotation speed.  
    For the ix4-200d specifically, the units shipped with either a 500GB, 1TB, or 2TB Seagate Barracuda LP (5900rpm) Hepburn disks.  ST3500412AS, ST31000520AS, ST32000542AS
    That is what the ix4-200d units were qualified to use.  Outside of those three specific drive models you will be dealing with hypothetically compatible disk options. 
    The recommendations that Wesley made previously are correct.  You should go though the ix4-300d list find a model that is similar to the stock drive or at least within the capacity limits of the device model.  (ix4--200d is 2TB disks, ix4-200dce is 3TB disks)
    If a different disk models are used in either version of the ix4-200d, it is highly recommended that all disks be eventually replaced with the new model of disk for RAID stability.  to do this, the Capacity Upgrade Guide should be followed.

  • Disk Spindown on ix4-200d fw3.2.10... cloud

    Greetings!
    After many years of dedicated service, a drive in my NAS has failed. These disks are discontinued and unavailable from Iomega/Lenovo, and I can only find reconditioned drives online, which I prefer not to use.
    I took this as an opportunity to upgrade the NAS with 4 new Toshiba DT01ACA300 3TB drives with the understanding that they are not on any 'supported' list for this box.
    All is working well with the exception of one thing. The new drives do not spin down regardless of the setting selected in the green settings. The NAS sits idle for 75% of the day, so it is reasonable to have them spin down.
    I've been tempted to experiment with the linux command start-up procedures, but thought I might first get the insight and opinions of the experts first to help guide me to the correct path.
    I've turned off all services except windows and MAC file access and SSH. I've read that some of the services can prevent spindown from being triggered.
    Console boot shows a call to hdparm that does not set any params. This was true of the original disks as well, so I find myself not understanding the mechanism used to control spindown timing/control.
    I am linux experienced and am comfortable with operating system configurations, so feel free to advise in any configuration adjustments you feel would be helpful.
    Thank You,
    Doug.

  • Ix4-200d CE locking up on device restart after FW update to 3.2.10.30101

    I updated the firmware on my iOmega StorCenter ix4-200d CE (4TB) to 3.2.10.30101 last night from 3.2.8.30031. After it uploaded to my NAS, it started to do it's normal shutdown, followed by the power up. Everything was going well until the power up, where it has locked up at 95%. There were no messages at all that came up either via the web interface, or on the LCD screen on the front of the device itself. 
    Has anyone else run in to this problem? Does anyone know of a solution? I have powered it off twice, and turned it back on. I get the same results. 
    Can I maybe load the previous version of the firmware on to a USB key, and install that without using the web interface, or losing any data? 
    EDIT: I should add, that it does show up as connected to my network when I look at the connected devices on my router. Upon seeing that, I decided to see if I could access the drives over my network, and oddly I can. I can access them both from my MacBoook Pro running Mavericks, as well as my PS3 which I use to access the Media Server on my NAS. My TimeMachine back ups are also still going to the NAS, and I can copy files too, and from it. 
    So it appears it has fully restarted, but the  device itself on it's LCD screen, the web GUI, and the LenovaEMC Storage Manager keep saying that it is still "restarting", not allowing me to do any managment of the device. 

    Hello SurveyGeek
    If your device did not seem to complete like others did on this forum thread, please try the following.
    - Backup any critical data from the unit if another copy does not already exist. 
    - Power down the unit swap the first and last hard drives so they are in opposite bays and also re-seat the remaining disks.
    - Reconnect power cable and allow unit to boot.  you should close all previous web sessions to help speed up the boot process.
    - If the issue persists please contact LenovoEMC support to review the issue further.

  • DIY Fusion Drive and RAID 5

    Hi everyone!
    I have spent several hours by reading various forums but haven’t found any definitive answers.
    I have a 12 Core Mac Pro with the following setup: one 1TB SATA hard drive that carries the system and applications. For the files and storage there are three 2TB SATA drives in RAID 5 controlled by Apple RAID card. I am going to install a 512 GB Samsung 840 Pro SSD drive in the optical bay and have initially planned to use it just for the system and applications, but am curious if the following is possible.
    1) Is it possible to combine the RAID 5 array with the SSD and create a Fusion drive?
    2) If yes, will it retain all the features of the RAID 5?
    3) Should TRIM be enabled?
    Thank you in advance!

    TRIM directly addresses the shortcomings of having only garbage collection available. SSD controller manufacturers and designers (including SandForce, the controller manufacturer for OWC's SSDs), recommends that TRIM be used with their products. So does Samsung. 
    For example, here's a 2011 article from OWC describing how you don't need TRIM on their SSDs and how it can in fact hurt performance or reliability.
    That article has been discussed here on MacInTouch before. In my opinion it's bad advice, and inaccurate in some of its assertions. It also ignores the recommendation made by SandForce to use TRIM with their SSD controllers. But even if one were to take that article at face value, applying that advice to SSDs other than OWC's makes little sense.
    The reason I'm advising against TRIM is simply that it's yet another driver-level modification of the OS, and these always carry potential risk (as all the folks with WD hard drives who lost data can attest to).
    Apples and oranges comparison, for a variety of reasons. The short of it is that TRIM is supported natively in all recent versions of OS X. The tools used to enable it for third party SSDs do not add a new kernel extension; they change the setting to allow Apple's native TRIM implementation to be used with SSDs other than those factory installed by Apple.
    This shows that the 840s do work slightly better with TRIM than without, but the differences are (in my opinion) trivial, a 9% increase at best.
    One of the major reasons for the skepticism that exists about TRIM is that so many people, the authors of both articles you linked to included, don't understand it.
    TRIM is not, strictly speaking, a performance-enhancement technology -- though it is plainly obvious that most people think it is.
    Though it can, in many circumstances, improve performance, there are also circumstances under which it will provide little or no noticeable benefit. Not coincidentally, a new SSD tested fresh out of the factory packaging is unlikely to show much (if any) benefit. Or rather, TRIM is providing a real benefit for new SSDs, but that benefit doesn't become measurable in terms of benchmark performance testing until every memory cell in the SSD -- including many gigabytes of cells hidden from visibility by the SSD controller -- have been written to at least once. Writing 128 GB of files to an SSD with a nominal capacity of 128 GB won't do it, as there are several gigabytes (exact number varies depending on the model) still unwritten.
    Under real-world use conditions, having TRIM disabled means eventually having noticeable write performance degradation due to write amplification. It is far greater than "9%" -- it can be a 50% or greater drop in write performance, depending on various factors. Defining "eventually" is difficult because it depends on how the SSD is used. But given enough time and write cycles, it can happen to all SSDs used without TRIM, no matter how sophisticated their garbage collection algorithms are.
    Under those same real-world use conditions, having TRIM enabled means that the SSD should almost never reach a state of having noticeable write performance degradation, as it should almost never get into a state where write amplification is happening.
    I will concede that it is possible to design a lab test in such a way as to defeat the benefits provided by TRIM, but such tests do not reflect any real-world usage scenario I can imagine. Furthermore, those same contrived tests would put an un-TRIMmed drive into an equally-addled state even more quickly.
    I would suggest reading through the rather lengthy previous discussions about TRIM. Here are a couple of my past posts that are most relevant to the current discussion:
    A description of what TRIM is here.
    I addressed some of OWC Larry's comments about TRIM use with OWC/SandForce SSDs here.

  • Ix4-200d firmware update

    Is there any way to update the firmware via USB (from a flash drive)?

    Hello esurplusplus
    There is a way to flash the firmware via usb on ix4 units, however this is completely data destructive so it is not considered an update process.
    If you have an ix4-200d I recommend checking the nas-central.org forums, they should have guides on preparing a usb flash drive for firmware imaging.
    If you have an ix4-200d CE that is in warranty or if you are having issues updating to the latest firmware, please contact support as we still have the 3.2.6 imager utility which helps if your device is stuck at an older 3.0.x firmware.
    If you are just trying to load the firmware due to formating all disks, purchasing an empty ix4-200d CE, or replacing all the disks at the same time, I can not say for certain that support would assist with an imager as those situations are handled per case.

  • Extrenal Hard Drive with Raid 1 option won't mount through Airport Extreme

    I just purchased the new Airport Extreme and the Iomega UltraMax Desktop Hard drive, 1TB. The hard drive has Raid options. I plugged the hard drive into the back of the Airport Extreme through USB and if I have the hard drive set up to be Mirrored (Raid 1), the hard drive will not show up on my desktop.
    I switched the hard drive back to Striped (Raid 0) and it shows up. However, if I open the Airport Utility, the hard drive doesn't show up there. I also can't see the drive by going into the disk utility either so I can format the drive before using it.
    Any idea why this doesn't work as Raid 1 through the Airport Extreme and then I'm puzzled with why it doesn't show up in the Airport Utility nor in the Disk Utility.
    I want to be able to access this hard drive with a laptop eventually and I also want to make sure that I protect my data by using the Raid 1 option.
    Can anyone please help me figure out these issues?

    Sure. Forget about the AirDisk and buy one of these:
    http://www.dlink.com/products/?pid=509 - It's a D-Link DNS-323 2 drive bay SATA NAS box, and shouldn't cost you more than $185 without drives. It has Gigabit Ethernet, supports SMB and AFP (it'll work with Windows machines and Macs), and it even runs an iTunes server inside the box.
    http://preview.tinyurl.com/32vfc3 - Maxtor 500GB drives for $100 each shipped.
    So for ~$385, you can have 1TB of space which you can then array as RAID 0 or 1, or use as a big, contiguous drive.

  • Can i recover lost data from encrypted drive by Bitlocker

    Hello Dears. I had encrypted my drive by Bitlocker in windows 7. 
    few days after my friend did quick format in my encrypted drive.
    my 300 gb of data lost. and nothing saved
    i remember unlock password. 
    how can i recover my data ??? i need my data
    i tried drive recovering tools (advanced EFS data recovery, easeus . . ,) . but . . . it's encrypted and formatted drive. 
    can i undo quick format and decrypt ???
    sorry my english is not good.
    someone help me please. 

    BitLocker is not the cause of failed to recover files. 
    Format a drive will clear all data saved on the hard disk. Thus recovery formatted data will be a hard disk based technology but not related to operation system. There is no build-in data recovery feature in Windows operations. So we will needto use third party recovery tool or contact third party data recovery company for current issue.
    As recovery missing data service will be expensive, we can also check emails and contact friends to see if that can help get a part of files back especially for photos, documents etc.
