Installing a New drive to a RAID 1

Imtrying to set up a RAID 1 for mirroring the primary drive in case of failure.  The RAID card does not recognize the new drive.  This is probably a dumb question, but do I need to format the drive first? I thought that for mirroring, you had to have an unformatted drive?

Yes, but with Ghost you would have to update the ghost backup every time any of the contents of the primary changed.  With RAID 1 you have a hot mirror you can use.
Maybe you need to have both drives set to master on the drive itself and have them on seperate ide channels on the RAID card?

What type of RAID card do you have? SCSI or IDE?
Can you get into the BIOS for the RAID card?

Yes I can.  Its an Adaptec IDE Card

Stupid question, but is the new drive you are installing the same size as the old drive?
Are there jumper settings on the drive that you need to change?

The new drive is actually the exact brand and model of the boot drive.  Again, remember its not formatted or partitioned at this point.  I had thought you dont want to partition or format a drive when your going to use it to do a RAID1?

No, you dont normally have to format or partition a drive when using RAID.
What you will need to do is go into the BIOS of the RAID card and add the new drive as a mirror.
Does the BIOS of the RAID card see the new drive as being installed?

The RAID bios does not see the new drive...only the boot drive.

You need 2 drives for a mirror...and both must be connected to the RAID card. How are you trying to set this up? T

Have you tested that the new drive is working OK?  Is it OK in another system?  It doesnt need to be formatted or partitioned, just visible in the BIOS

Another thing....how is the cabling setup for 2 drives?  Are they on the same cable from the RAID card or seperate?

CallandorCommented:
For best performance, each drive should be on a separate cable.  Did you try the drive just as a plain old IDE disk and use the regular controller to see if it can be detected?  We need to eliminate whether this is a hard drive problem.

So the drive IS detected in BIOS on another PC but only when set as a master...NOT DETECTED when set to Slave or CS.  Tommorrow when I go back and try it in the original PC, if it also sees it as master I guess that'll work. The whole purpose of this is to have an immediate replacement in case of pri drive failure.  Couldn't I accomplish the same thing by installing Ghost and having it make the image on this 2nd drive tho?  Instead of going with a RAID 1?

Well, Ghost is used to make a snapshot at a given point in time; RAID-1 is a real-time backup that is always up-to-date.
