Well had my PC for a Bit now and found that as i have two drive's one is a fast reading DVD drive and the other is a blu ray Burner i noticed that the DVD was vanishing
Nothing showing in the Device manager
so after trolling the Net i see this is a issue and many have this Now both are Satter
I Noticed that My Blue ray Drive E: was in Sata 1 and my DVD Drive D: was in Sata 3
Now at this point i must point out this was a Bult computer (wife bought it ) so i did not do the build
so this is How i fixed this swopped the sata cables over then changed the drive Letters
No messing in the BIOS and no Microsoft Fix
Basicly Hard drive = Sata 1 Drive C:\
Firts Optical = sata 2 Drive D:\
Secound = Sata 3 Drive E:\
Then also windows sorts the Channel numbers out this only seams to afect sata Optical drives
