So I went out to look at a video server the other day that had degraded raid issues. I've read about the various raid levels and how they are supposed to work, but the behavior I witnessed here has me a bit baffled.
The Raid 1 drive was marked as degraded. The system actually incorrectly id'd the culprit drive (verified by chkdsk), but what was really weird was it looked like the raid stopped trying to mirror the two drives months ago, but only gave an alert a few days ago. There are no files or event logs younger than 5/14 on the bad drive. It's boot-able, but has a tonne of bad sectors that are causing rampant blue screens.
Finally, since the good drive was marked as degraded, the system wouldn't boot from it, the raid had to be broken (after file backup!) and then a new one created live in the Intel matrix manager.
Is this behavior the result of the slow death of the bad drive? Is it anomalous? Is it something I may expect to see again?
