Yeah, most people aren't convinced until something fails catastrophically. Make sure your backups are good.Also, it isn't necessarily the physical drive. Could be the firmware, drives, switch, cache, any filter drivers in the IO stack, etc. In short, anything between SQL and the physical disk platters. In most systems these days, that's a lot of parts.
The hardware support team concluded that because the temperature was unusually high on the drive (84 C), that was probably the cause. I'm told that we've installed some kind of extra cooling on it and now it's back within typical operational temperatures.
