I also searched for NTFS boot sector patterns (signature: EB 52 90 4E 54 46 53 20 20 20 20). (Drives 1 and 2 had "00" hexadecimal values at their beginning.) The MBR (signature 33 C0 8E D0 BC) was located at the following offsets: I also did some analysis of the drives with an hexadecimal editor. The docks in which the drives are were powered on respecting the order of the drives had in the NAS (1, 2, 3, 4). So, here are the screenshots of the disk manager and UFS RAID Recovery.
Should anything go not as planned, I'll be happy to help recovering the data from this NAS remotely. Start with UFS Explorer, I believe RAID Recovery edition (as well as Professional) will reassemble it automatically: If nothing else has failed or has been done by the client, cloning the drives and recovering them as RAID 5 should work smoothly. Moreover, your description (if everything's correct) suggests that you're dealing with RAID5. I usually forget such technical details rather quickly, but if I'm correct, WD Sentinels can work in RAID1 mode only if it's a two-drive model or if there are only two drives inserted.

The manual suggests that the maximal RAID 1 storage capacity for this system is 2 TB. We received a WD Sentinel DX4000 NAS storage with 4 x 2 TB. Should I assume a RAID 5 system and try reassembling the third partition of drives #1 and #2 with the unique partition of drives #3 and #4 ?

I hope that there is no encryption, BitLocker or else.Ģ) Restoring/reinstalling the system, if possible with the data, otherwise without the data, but after their recovery.ĭoes anyone here had some experience with the WD Sentinel series ? The manual suggests that the user can unlock the storage using a password. There is some reset button at the backpane of the NAS, but I don't want to play with this, unless all drives were cloned first. However, what I find strange if the system partition was in RAID 1 is that no file system is detected.Īs this NAS is running Windows, I expected the system partition being NTFS or so.

So, my assumption is that there might be some RAID 1 by default for the system partition, on which Windows Storage Server 2008 R2 Essentials should be installe, as there is such license sticker at the back pane of the NAS, and then from within Windows, the description of some logical drive, spanning over the remaining space of all drives, or alternatively RAID 5. However, the manual suggests that the maximal RAID 1 storage capacity for this system is 2 TB, and this is also in contractiction which the size of the third partition (5528.78 GB), which suggests that at least three drives are used. The identical partititioning shemes of drives #1 and #2 could suggest this. The computer technician who usually cares for this company believes that the system was in RAID 1. So, there is some conflict between the two drives, as they were same.ĭrive #3 as well as drive #4 have a unique RAW partition which covers all the drive.
5528.78 RAW When drives #4 is attached to another computer, whilst drive #3 is, it is not "In line" but "Off line" in the disk manager.īut when attached alone, it is becomes "In line".
