Mac Pro raid will not wake from sleep

[SmilesLots]

I have the 1.1 Mac Pro with a software raid 0 of two Seagate 2tb drives for 4TB total. Whenever I put the computer to sleep it will not wake up. My Seagate single 1.5 TB drive wakes with no problem. Any ideas? TIA

wow. how very odd. have you attempted to repair disk permissions with the OSX disc? i would start there.

what OSX version are you running?

Try those steps even though it's not "made" for you but it sums up the same methods I would suggest anyway

OS 10.6.3 - like in my sig
I'll give the disk a try; been using SL cache cleaner almost daily.
Thanks

oh! my mistake, apologies.

SL cache cleaner doesnt really do much - it is really worth trying the boot disc first of all, then we can go from there.

has this always been happening?
