Test that mirrored drive is working?

July 28, 2009 at 01:24:02
Specs: Windows XP
Ive have two external raid hardrive arrays both set to raid 1.
Having read some horror stories that sometimes the configuration can fail with out notice and then find that the data hasnt been copied, is there a utility that allows me to look at and/or check that the mirrored drive is healthy and is indeed backing up everything from the first drive?

Running a RAID1 array is a good idea but is not a replacement for regular backup/imaging.

I am not qualified to answer your original question with any authority. That said, Googling for that query will produce many good hits. Try [how to test a RAID 1 array].

Thanks for the reply...
I use my raid for a daily back up....I have 3 copies of everything then...
Ive done a bit of a hunt on the net but there doesnt seem to be anything that can look specifically at the mirrored drive.
Im not that technical so maybe Im not looking in the right places.

"I have 3 copies of everything then..."

You are very wise Matt. I also keep 3 copies of everything on my system, but I agree with Othehill. I don't trust raid and do my backups myself. I also occasionally run Beyond Compare to compare my backups.

the best way to simulate fault tolerance is to simulate a fault: unplug one of the HDDs and see if the data is still accessible. Now unplug the other one and check again.

Thanks for all the input guys...

I have read that this is the way to test to see if a mirrored drive is working properly.
It seems a very primitive way of doing it though.
I cant help thinking that there must be a utility that can check these things.....it is a physical drive with data on it after all!

While Googling I did find a couple of methods.

primitive, yes, BUT the fact remains that by introducing new methods of testing, you introduce new variables. if you disconnect a HDD and can still access your data you KNOW that your RAID1 is fault tolerant.

it scares me a little to rely on 3rd party utilities to tell me i'm all good, because how do i know that the utilities are working right...?

This is true.....I guess Im looking for something that allows you to see the drives data as you can with the 'c' drive for example.

Thanks for the responses guys...

I have tried this last app...the Intel Matrix Storage Manager but it wouldnt install on my machine...probably an imcompatible chipset.

Oh well looks like I will have to check things the hard way.
