RAID10 Recovery in UFS Explorer

March 8th, 2012, 11:25

Hi,
I am trying to recover my data from raid10 (ext4 filesystem) with Ufs Explorer Standard Recovery. I have three disk images (one missing disk is damaged).

I used plugin to build virutal raid. I added ext4 partition as first and unkown partition as second.

In "raid preview" filesystem is opened but I see only one dir named "lost+founds" and it is empty...

2 questions.
From the 3 drives, have you found out already which ones are belonging to the RAID0?
Also, are you sure about the stripe size?

All disks will have MBR because striping does not start at sector 0. This is why you see all same information.

Use Winhex to look at sector 20975619, should be Linux superblock at at least 1 disk. Other disk should have empty space (probably)

first partition is system (gentoo), second swap and data is on third and fourth partitions.

it is mdadm software raid with default options (chunk-size=512)
I think sdd does not contain valid file system..

And have you compared sdb and sdd to check if the content is the same?

This should be fairly simple case. If it is giving you so much problems then let someone else handle it for you. Very likely it can be handled remotely.

Contact DR-Kiev,

He will be able to rebuild your RAID remotely for a small fee.
