i suffer the same issue

There is an endemic problem with OCZ and likely all PCI-e based SSDs is that the power to the expansion slot appears to die before Windows is finished doing its shut-down thing. The only solution at this point appears to be to do a re-start as opposed to a shut-down and to turn the computer off when it starts to reboot, before the drive is accessed.

SITE RESPONSE: It is unfortunate that you have had such troubles and we can only relate our experience on views on same. The Revo card is still installed in our test bench and there hasn’t been any difficulties experience whatsoever. If a thought could be offered… You appear to be a very tech rounded individual and I wonder if it is possible that you have fine tuned your system with a quick shutdown. I mention this because, I have read other complaints of similar when people shut down windows improperly and same occuring. If you have adjusted your registry tweaks for a quicker shutdown, although all seems to be perfect, it could be cutting short the proper closure of services, one of which that might cause the result you are experiencing. In any case, good luck and hope you find the root of the problem.
