My pc is set up with a Raid1. I have dual 280g WD drives that make up the Raid and are used for data only. I have a 3rd drive, 80g WD, for my programs. Last night I re-booted my pc (I keep it in hibernate mode most of the time so I re-boot once in a while just for g.p.) and now it doesn't recognize either Raid drive. The Bios doesn't see them either although it does show the Raid drivers are still there. I don't know what to do next. If someone could explain in plain english, I would appreciate it. I have a custom built system but the person who built it for me is no longer around.
Thanks!

Please supply the following information: Operating system, processor, motherboard, power supply amount of Ram. Are you using software for Raid (for example if you are using a intel chipset Intel Matrix Storage Manager), if you are using hardware for Raid (for example a Adaptec or Promise Raid card). What are you setting in the BIOS for you drives? Did you do a BIOS update recently? Usually you do not see the volume not the individual drives. You shoul ony see the 80GB drive.

To howardp6:

I will do my best to give you what info I can. I am no pc geek, so please bear with me.

O/S is Windows XP home edition, with SP3, AMD Athlon 64, ASUS K8-NE deluxe motherboard, 600 watt power supply, 2 gigs ram. My drives are WD, all 3 of them. I am not sure what you are asking as far as BIOS settings...please explain and I'll look. No, I did not do a BIOS update recently. The 80g drive is the drive I have all of my programs on. The RAID is what I have all my data on.

Thanks for your response and help.

Boot into your RAID BIOS to see if your array is degraded or failed.

I'm not sure how to read it. I booted into the RAID BIOS and it shows the 2 drives. One has a zero next to it and the other has a 2. I attempted to do a rebuild but it said I had an invalid setup. I removed the drives from the tower and then put them back hoping it might be a cable or something. Still got the same response...nothing.

Did you put them back in same position they were in?

Normally, you'll boot into the RAID BIOS and you'll see your array with a status next to it. Here is where you define the array

Here is a thread that has some nice images of the RAID BIOS

If you don't see an array set up, it has failed. If this is the case, you're out of luck. You'd have to define the array again and your data would be gone.

I don't have the nVidia RAID utility. F4 during boot up on my keyboard takes me into the DOS RAID utility. I discovered that one of the drives has failed. Now I am wondering how to get the data off of it. I accidentally erased the good one while trying to figure it all out. I am glad I still have the one good drive and glad I do regular back-ups to an external. I don't think I will go back to a RAID set-up...too much redundancy for personal use. I am not noticing much difference in data transfer without it either. I am now looking for data recovery recommendations.

Something like this may work. I've heard of it, but never used it.
