Raid 1 Degraded What do?

I have two Western Digital WD Black WD2002FAEX 2TB 7200 in Raid 1
In my BIO's, the status is degraded for the past whatever months.
I now decided to finally fix the bloody problem back to normal.

I'm using HD Tune Pro 5.50 to check for error scans but all turns green.
Used WD Data Lifeguard Diagnostic and everything all checked green and Passed.
Yes I plugged a non-Raid Sata port into the hard drive.

I have no idea which drive is dying slowly.

One thing that also bothers me when I only plugged one of the drive in:
Drive #1: Has 6GB of free space left - Has everything
Drive #2: Has 32GB of free space - I have no idea what is missing?

Why aren't they the same? I thought Raid 1 was suppose to copy every files.

Drives were never replaced, bought and installed last year of April.

When it says the array is degraded, it should say which drive it is (by SATA port number and drive serial number).
 
If a drive failed or is failing, it should show up during POST when the RAID utility comes up. It should also say it in the RAID utility itself should you enter it.

As far as the free drive space, that's probably why the array is failing. It's not doing the duplication like it is supposed to.
 
Push comes to shove, just break the array and boot singly off the drives. the one with 6GB free is the master. I don't know if the second drive is failing, if it's simply a software bug that degraded the array or something else. In any event, you can rebuild off the master drive. You could try with everything as you have it now (ie try to have your raid manager rebuild the array) as it sounds like your drives may be fine. I'm assuming you tested out both drives for errors.

I tested both drives with HD Tune Pro and everything is green on the error scan.

I'm using the BIO's for raid. How do I rebuild using BIOs?

Attached a picture of my BIO's, doesn't say which one is dying of sorts.

So above the post, the picture shows the RAID status is rebuilding after I disconnect both drives, plugged into a non-raid port for error scan, plugged both drives back into RAID ports, JUST restarted my computer, status is now normal....what?
 
If it rebuilt the mirror you are probably good. If it degrades again it's likely a drive problem.

Generally the RAID software (either the BIOS or whatever it presents in Windows/your OS) is where you go to rebuild it.

How do I rebuild using BIOs? It said something about rebuilding within your OS.
