Raid degraded

I have a Win 2003 Server with an Apdaptec 1210SA Raid card. There are two hard drives in a Raid 1 set. The server has been running slow lately. When I reboot the server, it shows both hard drives are healthy, but it says that the raid is degraded. Could this problem be the raid card itself since it shows both hard drives healthy? Any suggestions? Also, if I put a new hard drive in, can I add it to the raid and rebuild without losing the data on the other drive?

hi,
I cannot know the motivation, but a RAID1
* slow
* both HD healthy
* defined Degraded

is in rebuilding state. I should wait for a while.

Why would it be rebuilding? These hard drives have been in the machine for over 4 years. What is wrong with Raid 1?

hi,
I agree.

If you can, reboot and see if there is some % of rebuilding.

In the case of a disk was failed and re-healthy, and no more in the RAID, then this degraded, performances would be normal (but in critical state).

Wait for a while (weekend) and if monday still this situation, I'ld think to
open an HW call, but for Adaptec 1210SA.
Just a question: has this card a battery ? (it seems no, but...)

hi,
have you installed (on Win) Storage Manager ?

http://www.adaptec.com/en-US/downloads/storage_manager/sm?productId=AAR-1210SA&dn=Adaptec+Serial+ATA+RAID+1210SA

by this you can see events in the card.

Thank you for the link to storage manager. I installed the program and it gave me the following.
It says failed drive: controller 1, port 0 and it gives me the hard drive model #.

Now, if I replace the bad drive, I need to add the new one to the raid and rebuild it. If I rebuild it, will I lose my data on the good drive or will it just build the new drive.

Thanks
