I have a raid 1 that has failed partially. The controller tells me the raid is degraded, but does not tell me which drive is failing.
When I look in My Computer, I see that the controller split my raid 1 two the separate drives, so now I have two of the same partitions. I can read data from both them just fine. The SMART status is being dumb and says no errors.
One drive is making a clicking sound, but I can't tell which one. Can I amplify the sound some how to locate it?
What are some tricks/tips I can do to figure out which drive is failing without taking the computer down and swapping drives? I am trying to minimize down time.

Poor man's stethoscope: Long'ish screwdriver. Tip on the drive, handle on your ear. Listen to each drive. If either clicks you should be able to quickly isolate it.
(Works great with valve-covers on your old cars when listening for valve noise too ;-) )
Of course, this assumes clearance and common sense about where on the drive you touch...
