Disappearing RAID array

I am running Windows 7 -64 bit Professional
The system boots off a 10K velociraptor

I also have a RAID 5 set up for my data through a Silicon Image Sil 3124 running in one of the spare PCI-E slots. It comes on just fine (as Drive D) and is a fast as I had hoped it would be.

Frequently, usually after the system has gone to sleep, the drive just plain DISAPPEARS.
I have to reboot to bring it back to life on the system.

Two questions; toward the same end.
1) How do I get it to stop disappearing?
2) How do I get Windows 7 from going to sleep? I’ve messed round with the power options in the control panel and I’ve come to the conclusion that Windows 7 -64 bit is narcoleptic

  1. I have the exact same problem... it's actually quite eerie.

    I'm using the same HDD for booting, same OS, same RAID (5) for D:\, and the same thing happens to me. The only difference is I'm using a slightly different model raid controller (3114 instead of 3124).

    I've reinstalled drivers a couple times and I am positive they are the latest ones.

    Don, if you've found the answer that doesn't involve changing the power settings, I'd love to hear it!

  2. I just flashed the firmware after I noticed it was out of date. Not sure if that will solve the issue, but it's another thing to keep in mind.
