HowTo : Recover Intel RAID "Non-Member Disk" Error.. - Page 24

post #231 of 287
Changed ram kits and the BIOS reset which caused my RAID0 to fail giving me non-member disk. My first attempt was to disable RAID and re-enable... which did nothing

Like Post #1 says:

Enter RAID BIOS
Delete current RAID
Create exact RAID
boot Windows
Run testdisk_win.exe
Select RAID
Let it scan (took 5 seconds)
Select Partition & Write

Reboot. Enter Disk Management and resign the correct Drive letter.

Thank you so much! you saved me 500GB of re-downloading Steam/uPlay/Origin games again thumb.gif

so long story short, after hours and hours of restarts/scans/tests i found out that my RAM was physically loose doh.gifdoh.gifdoh.gifdoh.gifdoh.gif (5 required, 1 for each hour).

and in the process of that fun 5 hours, my raid 0 array failed. both hard drives are both present in bios, and the intel raid controller menu (after bios, but b4 windows) . the intel raid controller says that one of the disks is a "Non-member disk". and the raid array fails.

this is what my winodws intel rapid storage tech shows



i think that the 932gb SATA disk on the bottom is the one that changed to "non-member disk" status during those restarts.should i fallow the steps in this thread (or even the post above me) to repair my raid 0 array? the only thing i don't know is the order of HDD's added to the array, but since its only 2, not rly hard to try both.

should i proceed with the steps in this thread for my current raid 0 failure?

i'm being cautious as i have an OS installed on there (yup, i was asking for it).

EDIT: id also like to point that i think what happened here is the raid array data for what HDD'S are part of it has be corrupted. in intel rapid storage tech the raid array is missing the HD with serial # "D-WMAW30549154:0" and the HDD that is currently a nun-member has a serial # "WD-WMAW30549154" . Is it possible to edit the array so it has the right serial #?

Thanks a lot this solved my issue I keep getting missing raid members when upgrading or downgrading windows. I'll remember this trick from now on, it's a lot quicker than recovering the info and repartitioning the drive. thumb.gif +1
post #234 of 287
So, I have a kindof interesting one, maybe someone has a clue. I am lead tech in a small repair shop and have used this and similar methods for RAID recovery in the past.
Last week, a heavily virus infected older Alienware comes in. I hand it off to a tech to work on. Normal first order of business for us is to check drive health. The existing windows install would not read smart stats with any of our normal tools, which is not unusual when RAID is involved.
The box has two 2TB WDs in a RAID 0, and was bootable and working (except for malware).
The tech labeled and pulled the drives to test individually on another system. When I do this I normally use a linux system that does not automount the drives. She used a windows system and an ATAPI bridge. I think that one of the drives mounted and had something written to it (perhaps automatically by windows/AV etc).
Now, one drive shows as non-member.
To be safe, I took ove at this point and took a DD image of both drives before proceeding with this procedure.

The strange thing is, the recreated RAID array is not the same size.
Before rebuild:
ARRAY0
RAID 0
Stripe 128k
Disk 1 - 1.8TB
Disk 2 - 1.8TB
Size 3.6 GB

After rebuild:
ARRAY0
RAID 0
Stripe 128k
Disk 1 - 1.8TB
Disk 2 - 1.8TB
Size 3.4 GB

It's an intel controller, and not many options at all, only stripe size and members, so this has me puzzled.

I am running testdisk now, but it is generating cyl, head count mismatches, and I am concerned. I know I can start again since I have the images.
Anyone have any ideas why this could have happened?
post #235 of 287
An update. Testdisk found the partitions, but the disk was too small to write them. I went to recreate the array again, and noticed that size is an option, but it states that the default is the largest possible and had it set at 3.51TB. I reset that to 3.6 and even though 3.51 is supposed to be the largest, it took. Testdisk is now rerunning, so we will see!

Been really impressed with the recovery success rate on this thread and was wondering if my situation can be recovered.

My raid 0 PC has 2 drives and has lost its raid partition. The machine has 2 drives in raid 0 which the PC boots from. Since the raid cannot be seen, windows cannot load.

I am wondering if i need to use a 3rd drive to install windows, hence allowing TestDisk to be installed. This will allow me to reconnect the raid and allow the posted steps on the thread to be followed to restore data from the raid.

Any help ?

yup, thats how i recovered mine. i allrdy had a 3rd HDD with a windows installation. i used that one to recover the lost raid array. GL with your recovery, its alot easier then it looks, just fallow the steps slowly.

Just got around to running windows on a different drive

When recreating the new raid on the existing array, does the data gets deleted?

The process prompts you that "All data will be lost"

Just checking if i'm following the procedure correctly

Hi,

please, where I can download or obtain TestDisk software ?
post #240 of 287
Awesome! I was able to copy all my files to my external drive and then repair the boot sector of my Raid10 setup! Back up and running... Kind of a pain when you have an OC rig and every time you have BIOS reset you have to go through this over and over again! mad.gif Makes a NAS sound more reasonable...
