I developed a full virtual scsi port driver that works perfect in XP (tested with driver verifier). Now I am moving forward to Win7 and all seems to work fine from the Windbg output, except that my virtual disk is not detected by the disk management console neither explorer, by other side the disk device is showed in the device manager. Recently there was a thread with a similar issue, but the solution found was not a real solution and also it does not work for me (disabling Virtual Disk Service) 
My client does not want the miniport option.
What is new in Win7?? What I am missing now???
Thanks in advance.
Look at the flow of SCSI commands to your disk, probably you fail something which is now mandatory.

Thanks, Maxim, that is what I am doing now. Just in case that some good guy already experimented this same issue and want to give me a simple and little hint, that will save me a lot of time 
Anyway if I find the answer I will write the solution here. I want to finish before the end of the year to celebrate in peace
