Sorry if Its delayed but I must have missed that little bit in the TOC if it said that new posts are delayed.
Windows 7 Home Premium, 64 bit
Gateway Laptop NV55C (I would upgrade ut currently not working so a major hardware upgrade is gonna have to wait 
I've got the latest SATA AHCI Driver for my system according to Gateway.
As for the latest Intel RST software/drivers, I have version 9.6.2.1001 on the IAStorDataMgrSvc.exe file, which is the same version as the SATA drivers I found on the Gateway site.
Lately, the last few weeks, I have been having problem with my DVD drive disappearing.
In the Intel RST app, its shows my HD on Internal Port 0; and Internal Port 1 as empty.
I've only just checked this status after my DVD disappeared.
I'm guessing that my DVD is on Port 1 because I get a dialog popping up saying something about Port 1 being removed. Then my DVD drive is gone.
If I reboot, it comes back.
And it may stay for 5 minutes or 5 days (or more), then the DVD just disappears with the Intel RST popup.
It lasted 1 hour 12 minutes this time.
Last time, it lasted about 5 minutes.
I may not be doing anything particular, youtube, working (EagleCad and other Circuit board and schematic design software, and related utilities), general web browsing. Nothing special and nothing I haven't been doing for years.
I do Windows updates on a fairly regular basis (At least once every 2 week if not once a week)
This does kind of have me wondering if a recent Windows update broke something.
It would not be the first time I have seen that happen.
And as a side note, although its been 7+ years, I used to work in IT repairing pretty much everything, so I'm comfortable getting waist deep into the guts of anything computer related if need be.
