Hi all,

For the First write, read is happening. Again for the subsequent writes it is in loop. (means same write is happening and same read data getting).

plz help me out.

Huh? You need to be more verbose. We do this for free, at least be appreciative enough of our time and take enough of your time to be clear about the issue you need help with.

Thanks,

Sorry for providing less info.

I am able to move ahead and completed read and write

I was using WdfRequestCompletewithPriorityboost for completion with Increment
and replaced this with WdfRequestCompletewithInformation it started yielding proper result

Thanks once again for your kind support and quick replies.

Using a priority boost on up completion yields better scheduling/performance, it does not fix programatic errors. I am guessing your bug is still there, now just more hidden.
