RAID 1 Disk Not Initialized error

mouthpiec · Jan 26, 2014

Currently my PC is configured as follows:

Disk C: on which Windows 7 is installed together with programs (no raid)
Disk D: on which all my files, photos etc are stored. this Disk is made up of two identical HDs and mirrored using RAID 1 with Windows

But today I noticed that one of the disk is not initialized ... what does this mean? Is the HD faulty?

When I right click on the disk and select "Re-Initialize"

Where do you see that the disk is not initialized?
If you have two drives in RAID, Windows should only see this as one disk.
If the RAID setup states the second disk is not initialized, it should give you the option to initialize it.

VincentP :

Thanks Vincent for the fast reply.
I am getting disk not initialized in Computer Management Window.

When I try to re-initialize the disk I am getting this

thanks again

You are using some volume spanning feature of Windows rather than any sort of RAID provided by your motherboard chipset or RAID controller.
I guess this is OK to prevent data loss, but performance won't be great.
Windows has identified the redundant volume as missing.
The uninitialised drive is not being recognised as the same drive.
Was it replaced?

Try right clicking on the missing disk and see if you can remove it from the volume.
Initialise Disk 1 as a dynamic disk and see if you can then add it to the volume as a redundant drive.

Yes I am using Windows Raid and I am quite happy with performance.
Disk was not replaced .. it was installed around 3 years ago and everything was fine.

When I right click on the disk I have the following:
-Initialize disk
-offline
-properties
-help

Which one I should select?

BTW in device manager the disks looks fine

I can't view any of your screen shots in Chrome.
Only capture2 worked in Internet Explorer.
What options do you get for the disk labelled as "missing"?
Did you change the SATA port the drive was connected to?

No hardware changes were made since I installed this PC ... shall I take a look at the cables maybe a cable become loose?
How can I upload the photos here pls?

VincentP · Jan 26, 2014

Can you view the same links if you open them on your PC? Surely "drive.google.com" works with Chrome. Maybe they didn't upload correctly.

mouthpiec · Jan 26, 2014

yes I can view the links with Chrome.
Try download this zip file.

That worked for your screen shots.
It could be a drive failure, I can't say for sure.

hmmmm .. thanks for your help. will check the cabling etc and then will see :/
If I replace the HD, will it sync with the 'good' HD without formatting ?

VincentP · Jan 26, 2014

You shouldn't need to format the new drive.
You should be able to initialize the new drive and add it to the volume as a redundant drive after removing the "missing" drive.
