The Solution Rating System

With so many solutions, how can you tell which solutions are most likely to help you and which ones are not? To provide you with a tool to use, we rate our solutions based on various elements that most accurately determine if a solution is a quality solution. To explain what factors affect the solution rating, here are the elements we take into consideration when formulating our solution rating.

The Grade of the Solution
The Zone Rank of the Expert Providing the Solution
The Number of Author and Expert Comments
The Number of Experts Contributing
The Feedback of the Community

Your Input Matters
Because of the way the system is set up, the most important variable in this equation is you. As a member of Experts Exchange, you are able to cast your vote on the quality of the solutions in regard to how complete, accurate, helpful and easy to understand each solution is. When you provide your feedback, each rating is adjusted accordingly. So, if you see a solution that has a poor rating that you think is a good solution, let us know by rating it. As you do, the rating will be adjusted and will become more accurate for other members of our site.

If you have any suggestions that you would like to make for our rating system, please ask a question in the Suggestions Zone of Community Support.

Determining Physical Drives in NT

Asked by mel150 in Windows NT Operating System

Tags: set, failed, fault, nt

I have a Windows NT 4.0 Server which contains 4 IDE drives. 2 of the drives are mirrored through Disk Admin that contain partitions C and D.
The other 2 drives are mirrored (RAID 1) and are Drive F:
I received an error in event viewer today that says "The Device \Device\Harddisk3\Ft1 that is part of a fault tolerance set has failed and will no longer be used"
When I open up Disk Administrator, it shows Mirror Set 4 is "Broken". And "Disk 3" is of course Red. I think its pretty safe to assume that Disk 3 is my problematic drive, BUT I'm wondering, when I open up the box how do I actually know which drive is Disk 3?
Unfortunatley, I cannot turn the machine off during the day being that its still our PDC, and when I open it up while its running, I cannot tell if one drive is physically dead or not. There doesn't seem to be an easy way for me to figure out which drive is the one that needs to be replaced.
I know which drives in the machine are mirrored for drive F, so I can narrow it down to two actual HDD's but while its running it appears that both drives are still functioning.

I had a chance to reboot the machine quickly thinking that maybe the mirror broke for some reason and after a reboot it would rebuild the other drive, but that did not work.

I was also thinking, what if I create a text file on Drive F, shut down the machine, unplug one of the HDD's and boot up. If I see the text file on Drive F, I probably have the Good drive plugged in...

Any better suggestions out there, or advice?

Thanks in advance.
