Problem with software mirror-best course of action

I have Server 2008 R2 installed, and setup with a software mirror. Today, after a power outage, the system wouldn't start. It had a message along the lines of 'could not start, file missing'.
I powered off and back on, and was presented with the options of booting to Server 2008 or 'Windows Secondary Plex'. I chose the secondary plex, to attempt booting to the secondary drive.
It booted no problem. But when I look at my disk manager now, the primary disk is not present. I tried to recan for disks, but no change. Is this normal, when you have booted to the secondary drive?
Also, what's the best course of action to get back to a point where I am setup with a working mirror again?

in most RAID sets you could pull the bad drive and it'd show as a broken mirror. than add in a new drive and rebuild the set.

backup backup backup, before you do anything, if your booted up plug in a USB drive, and make a copy of everything even kinda sorta important, copy to a network machine, and get a copy of acronis true image and do a dual destination backup image.

did I mention you should get a good back up immediately before you try to fix anything else?

Yep I already have a good backup-what next?
I'm not sure there's a problem with the drive itself, so I would like to mirror back to this drive again

with the relative cost of hard-drives compared to data, if in doubt toss it out,

pull the bad drive. and replace it. test the pulled drive it in another machine,  use manufacturer tools and if your really really sure it's ok, put it on the shelf to replace the next failure.

so for my money don't mess with a drive that failed in a server.

if you insist on reusing it, you should still be able to just pull it, break the mirror, than put the same drive back in and rebuild the set. every controller is different so make a phone call and confirm that your not going to mirror the empty drive onto the good one. you might need to move the 2nd drive to the 1st slot or something. again make the call to the controller manufacturer, or read the manual carefully.

Thanks. The reason I think the drive is ok is the specific error:

\windows\system32\winload.exe
status 0x000000f
the selected entry could not load because the application is missing or corrupt.

I had the same error a few months back with the same server, and replaced the disk. But I think its more of an issue with winload/bcedit.

I answered the question asked, rephrasing it should be a new question. introducing new facts at the end of the dialog, and not giving the points is sorta cruddy.

I don't see a question in the last post, I see a statement, that I took to relate why they aren't going to replace the drive, I would replace the drive in this case, I didn't agree with re-useing the drive. if there was another question In there I didn't see it.  I'm happy yo continue helping but I didn't realize it was a question.
