RAID 1 Critical

Posted on 2009-02-10

I purchased an ICY DOCK (, 2 x 1.5TB Seagate HDD (, and an ASUS M4A79 Deluxe motherboard (  I have an 80GB HDD as my boot drive and the 2 1.5 TB  drives in a RAID 1 in the ICY DOCK connected via eSATA.
Everything worked great for about 5 weeks, but this morning at boot the RAID 1 shows 'critical'.  I investigated the configuration and it shows 1 drive crashed or disconnected.  Wierd thing is though, when I boot it up, WinXP shows C:(80GB), D:(1.5TB), E:(DVD-ROM), and F:(1.5TB).  and the files on D and F are identical.  AND I am able to write to both drives independantly.
One happened and how do I fix my RAID 1 without losing data?

    so the raid array 1 is d: an f: thats why both drives show the same can you copy the data off the raid array
    It points to the icy dock raid controller is faulty so you may try and do a warranty swap out as it should be under warranty.

    huh?  the raid controller is on the motherboard, so my motherboard is bad?  Are you sure?  Is it possible to reconstruct the RAID 1 without loosing the data?  Maybe adding the 1 HDD back into the array?

    would i loose the data if i killed the array in the bios, then formatted 1 HDD and reconstructed the array.  would the data of the one be copied to the other?  or do both HDD have to be blank(formatted) when the array is constructed?

    Accepted Solution

    I had it set as BASIC instead of DYNAMIC and the drives got seperated in WinXP PRO.  So I backed up my data, rebuilt the RAID 1 , setting it to DYNAMIC this time.

    Setting the Dynamic option in Windows is not hardware RAID.  It is a software RAID solution that can be a nightmare to recover from.  I would recommend researching how to enable hardware raid in the icy dock documentation.
