Hello,

I have to recover the data on a raid1 array(2x maxtor 160GB). I don't know what controller / mobo the array was created on. The mobo I have is a ASUS A7B8X-E with silicon raid.

The individual drives are not recognised by windows but are recognised by the silicon raid utility.

In the raid utility:

Resolve Conflicts ->No conflicts exist!
Rebuild Mirrowed set -> No mirrored set. Press any key to return.

Will the create array option format the drives?

Basically need to get all the data & information.

Thanks

Creating an array will destroy the existing data.  Each controller has their own way of recording the array type.  You have to know which controller was used and use the same one.  It is possible that you could use a controller from the same manufacturer, but I have not tried that.
There might be a software application that might be able to reconstruct the raid, but can not think of the name.  You might be able to find it within experts-exchange. The utility might let you see the contents on the drive. good luck.

There is a util at http://runtime.org/raid.htm that may help though not sure if it will work with Raid 1. This just recovers data it doesnt actually rebuild the raid it needs somewhere to write the data . Also it costs 99$.

Can you bring the disk online if you leave one out of the controller. ie, it is a broken pair? This might allow the disk to be brought online as a single drive. You can then remove the data and rebuild the array if you need the array itself.

You should be able to do this on any controller. if it fails, at least you have the other half of the array.

Raid 1 is a mirror, So just connect one of the drives to a PC as a 2nd disk, start that PC normal OS and then you should have access to the other drive and copy the data you need off. You don't need raid to copy data from mirrored HD's.

I think Ipkon networks soloution could have had its merits, perhaps not as well put as Rindl's but similar.

Thank you for everyone who tried to help!!!!

My solution in the end was very simple, I tried with another mobo (Asrock) and the hard drive was detected as a second drive in Windows as rindi suggested. But the Asus mobo did not want to detect the drive. I think all had valid suggestion that may work in different situations so I devided the points.

Cheers
