Pioneer DVR K06 MISSING in Windows 7 (possible DMA issu

Greetings to everyone

I’ve been experiencing issues with my Pioneer DVR K06 slim DVDRW drive that is connected to my HTPC. Being a slim laptop drive I have attached a sata adapter which is detected in the bios, and allows me to boot from the disc, but when booting into Windows 7 x86 & the drive is missing and the boot time takes a long time.

I have tried all the tutorials in regards to missing DVD drive in Windows 7 but none of them seem to work. It takes a lot longer to load windows then usual boot time and if I insert a disc just before the windows boot sequence starts it detects the drive and boots into windows a lot faster with the drive detected.

Has anyone experienced the same problem and manage to find a solution to fix it. Any advice would be greatly appreciated as I have run out of options and have absolutely no idea. I have been pointed out that it might be a DMA issue but unsure how to disable or modify the DMA

Below are two snap shots of regedit and device manager

any help would be greatly appreciated as this has been an ongoing issue for quite some time

Cheers

I've tried re installing Windows 7 with my NEC DVDRW and it works fine. I then disconnected the drive and reconnected my Pioneer drive and the same problem has occurred.

Maybe the SATA adapter is not compatible with Windows 7.

Below is how the adapter looks
