Yesterday when I switched on my machine I got the message that the 1st array status was critical and it suggested that 1 disk was not responding or had failed. The screen went black and the machine would not boot.
I had a look in the BIOS at the boot settings and found listed under boot devices the following:
RAID array 2
RAID array 3
Single Disk 1
So I selected Single Disk 1 as the boot device and the machine started up and I was able to get into Windows. Under Computer I could see the operational data array as D:\ but I could also see both disks from the failed array as C:\ and H:\. This suggests to me that neither of the disks has actually failed but that the RAID array has somehow become corrupted and needs to be rebuilt.
In the BIOS/RAID setup options there is no option to rebuild an array and my motherboard manual also does not give information on rebuilding an array - only creating one in the first place.
I called the company who I ordered the machine from as I got a free 3 year warrantee with the machine. They were very unhelpful and told me to search the internet for a fix! And I dont really want to have to ship my machine back to them as firstly it will take a long time and secondly I am sure they will wipe my OS and restore the machine to base which is exactly what I was trying to avoid in getting a machine with RAID 1 setup in the first place. So I've been searching the internet without alot of success. What I did find was a program called AMD RAIDXpert. This has showed me that Drive on Port 1 is assigned to 'JBOD' which I believe means that is the disk I am booting to as 'Single Disk 1'. Drive on Port 3 is assigned to Raid 1 LD 1. Whilst both disks show up as having 150.03GB capacity, the disk on Raid 1 LD 1 has only assigned 149.97GB. The disk on JBOD has assigned the full 150.03GB. So I am wondering if maybe one disk has picked up a bad sector or some such thing which has effectively made the disks different sizes and resulted in the corruption on the RAID 1 array??????
If someone can try to help me out with this I'd really appreciate it as I work from this PC every day and really need it fixed and to know my RAID 1 is giving me a reliable backup!
My system spec is as follows:
OS: Vista 64 Bit
Motherboard: Asus M4A79T Deluxe
Chipset: AMD 790FX/ SB750
RAM: 4GB DDR3 1600MHz
Hard Drives: 2x 150GB WD Velociraptor 10,000rpm in RAID 1 (This is the failed OS array)
2x 500GB 7200rpm Drives in RAID 1 (for Data)
Graphics Card: ATI Radeon HD 4870 1GB
I think that may be all the info required? I will be pleased to send any more info or screenshots (even if I have to make them with a camera!) etc at request.
Thank you in advance to anybody that tries to help me. You don't know how much it means to me.
