[Paulfromsurrey]

Good Morning

I have very strange situation.

I have these two drive they were setup as mirror raid
these both drive wd2003fzex-00SRLA0 were Western Digital Black working on window server 2012 r2
raid show erorr system does not boot so we try to back up the data

I was able to back up everything but I notice most recent files are missing specially 2020

folders within folders are missing Drive is working fine
heads are fine.

what really happened to those folder for 2020
we ran mft scan+index nothing shows up under deleted
scanning unused sector.

Anyone can help or guide or even by TeamViewer can help let me know.

Hello,
As you said they were mirror pair ,Have you tried logical recovery on both or in one only ,Might be one was offline since few months ?

+1 as Amarbir says, one drive has been offline for a longer time. Check the other drive, have seen this many times.

Hello Amarbir and Digital support

Max from acelab did tried that he said one of the drive is hangs up so he prefer to work work on the other mirror drive .
As drive was in mirror configuration it should have mirror data

if one one of the drive is offline other should have the current information.

but both the drive have the same informaiton

Both have the same file structure. They both missing a lot of information since april 01,2019

even user created after april no longer exist on the system.

So may be one of the drive was offline but I should have the data on the other drive

I was advised by max that I should try scan used space

so far no luck

Thank you Amarbir and Digital support

What do you mean by the drive 'hangs up' the data must be on that drive.

[Paulfromsurrey]

Yes Data is there but is older data

in both partition files is like all from april 2019

I created the image of the one of the drive

All files and folder are there but they do not have recent Data

seems like all the server reset back to april 2019
on april 9th server was working fine no problem
on april 13 they reported that server was not started it shows error in one of the raid drive

i tested the server drive they both have the data

they both have the data and but older

then i searched the folder name >>> all the sudden i can see other missing folders

all the sudden those folder disappeared

i never seen anything like this in 26 year

Let me know if anything else you can think off

So do you have a 100% image of the drives with no bad sectors?

[Paulfromsurrey]

i did created the image of the one of the drive

at this here is what I have done

1.Try to run same process on both the drive

1. complete disk analysis on that is done i running scan on used space

but it has been 3 days process is still running on both drive

Hello ,
If you have a clone copy of the Media ,Then i suggest you try to scan the entire media using rstudio , recovery explorer , getdataback also .

You have to create images of both drives to see if either of them have any bad sectors. Only when you have done that can you tell the condition of the RAID.

At any point, was a RAID rebuild performed?

My guess, just from reading this... you had one drive offline for some time (since April 2019). At some point, the drive that the computer was operating from also kicked offline and the system switched back to the old out of sync drive. Then, the up-to-date drive came back online and a rebuild was done cloning all sectors from the out-of-sync drive onto the other drive.

That would explain exactly what you are finding.

Hello Paul,

Try to check parity on the array. Also, what's file system on the raid?
