RAID array question / replacing

[bloodlet]

I'm going to pull out an existing RAID1 array - 2 hard drives. Once they are pulled and new array is setup, is it possible to go back to the original RAID1 array if I put those 2 old drives in / without losing any data ofcourse? Will the controller recognize the old RAID1?

Yes I am planning on backing up the data, but I would love to know the above.

You should be able to plug both drives back in and be ready to go.

Ok so the hard drives themselves contain some sort of marker to let the driver know they're in some sort of RAID. Do I have to go into hte Raid controller setup on bootup to select anything? or should it simply boot up as it used to...

Thanks for the info!

Yep. Typically the controller will write some sort of metadata to the drive to identify it as part of an array.
