HI guys, need some help with WD dx4000. We have this NAS, which was setup with one single boot drive partition C and D where OS was and in bay 3&4 we have 2x4Tb HDD as RAID1. Identical drive models WD40EFRX-68WT0N0. What happened, was that the boot drive failed and we had to replace it. It was replaced with supported 3Tb drive and we installed the OS. The NAS is booting up and we can access the unit, no problem there. We plugged back the mirrored drives and after booting up, the NAS was verifying them for 8h last night and after it was done, now the NAS comes with invalid drives and the drives are not visible in Windows. On this 2 drives we have the company data. First question is how can we get the data of the drives and second why suddenly the NAS will say the drives are not supported, if this drives worked before for couple of years with out a problem and how we can get them back to work.
You said the boot drive failed and you replaced it. How did you do this with one drive?
In any event you should be able to plug one of your data drives in a PC and read the data if it is still there. If it does not show perhaps send it to a data recovery firm or maybe try some data recovery software.
Plugged one of the drives in Win7 box and Win does not see it. It comes as foreign drive if I try to import the drive comes with Mirrored volume, Data not redundant. Not sure if I should try and import the drive or I will loose the data on it. The data is very important and on top of that the backup ext drive failed also. All if this happened within a week.
Still not sure how you loaded the OS?
I am fairly certain I have looked at data from the raid 1 in a PC but do not have the time to test it right now. You might want to look at something like this then.
Manage to get the drives visible again by installing WD drive enabler from here Software and Firmware Downloads WD Support
Now I got 2 New separate drives in Bay3 and Bay4, but no data on them. For what ever reason, WD did not keep the RAID. Any idea how to get the data back apart from trying plugging both drives into a PC and running RAID recovery software?
Not sure what happened, but after drives were visible with WD as single drives. I switched off the WD and plugged the drives into the same PC, which was seeing one drive as RAID. Booting up BIOS sees the drives, but going into Windows drives are not there. the same if i go to Disk Management, drives are not there. How now can I get the data, any ideas?
As I said, I have no clue how you got to where you are. The original setup was manually done by someone. A DX4000 at minimum started with two drives in a RAID 1. If any compatible drives were added it was converted o RAID 5. If you added 2 non compatible drives I suppose it is possible someone set them up as a software mirror in disk mgmt., or installed the Intel Raid tools.
1. Verify Drive Compatibility: Double-check the compatibility of the replacement 3TB drive with the NAS. While the 3TB drive worked for the OS, it might not be fully compatible with the RAID setup. The original boot drive was 4TB, and there could be compatibility issues when mixing different drive sizes in a RAID configuration.
5. Backup and Restore: If you manage to retrieve the data or set up the RAID array again, consider implementing a regular backup strategy to prevent such data loss scenarios in the future. Backing up your important data to an external storage or cloud service can provide an extra layer of protection.
6. Firmware and Software Updates: Check if there are any firmware or software updates available for your WD DX4000 NAS. Updating the firmware and any associated software might help resolve compatibility issues and improve the overall stability of the NAS.
