Hi,
I am hoping someone here can give me some guidance on setting up RAID...
I have Abit AN52 mobo with a built in nvidia RAID controller. Last year I set it up to run a mirror, and started to store pretty much all of my data on that drive. I've stored thousands of pictures...
Then last week I started getting "Access failure: Critical error on disk ST3160811AS (Port: SATA 1.0)." every 30 seconds. Since it was complaining about the same drive, I figured it must be going dead, so I broke the mirror and started to copy files onto a new (bigger) drive figuring I was ready for an upgrade anyway.
Then I discovered that the second drive was in a very funky state. It was mostly in the same state as when I first created the mirror, with exception of a few files here and there that were added over the last year. I mean, it had files that were deleted a long time ago!!!
The first disk was much worse off, as soon as I restarted with the disk connected to a regular SATA port windows decided to run chkdsk, which reported a whole bunch of errors and attempted to fix them. In short, I lost quite a bit of data.
This whole time the nvidia control panel reported my raid as HEALTHY (my ass).
So my questions are...
- why did this happen? Isn't it the point of RAID that data is mirrored? and why wasn't it mirrored
- I am thinking about setting up the RAID again, should I try nvraid or set it up via windows dynamic disks?
- is there some raid integrity utility that I can use?
Any help will be much appreciated
