Hi,

I have a newer Acer laptop with a Matshita UJ8E2Q DVD drive running on w10 64. It stopped working earlier and has started back up once then stopped again. I am getting a "code 45 device disconnected" in device manager but the drive gets power. I've tried reinstalling the driver as well as editing the registry with the EnumDevice edit and I don't have any lower or upper filters when I go to CurrentControlSet in the registry. Any additional ideas would be appreciated.

Thank you, I know this is the best course. I was gonna try this but the thing is so tightly put together with no instructions on disassembly/assembly except for a foreign video on youtube. I've taken apart my old dell to replace the cpu and inevitably broke a little clip that required a major replacement. I'm thinking of trying to just reinstall the OS...maybe something got corrupted in there. If that doesn't work then will take it someone to get the connections checked out.

That would be great. The dell drive would just slide out and had a simple screw. Is there usually a power and data connection and is the connection commonly made when it is slid in or would cables come out with it? This laptop goes nowhere, doesn't get knocked around at all.

It is an Aspire VN7-791 (V17 Nitro). There are two screw holes directly to the right and left of the "mouth" of the drive at the left edge of the laptop.

Also, the drive was no longer showing in device manager due to my tinkering. I tried removing and resinstalling IDE ATA/ATAPI Controllers and ran the below line again in cmd prompt and it is back (greyed out, code 45).

reg.exe add "HKLM\System\CurrentControlSet\Services\atapi\Controller0" /f /v EnumDevice1 /t REG_DWORD /d 0x00000001

Thanks. Yup, that's the video. Had seen it months ago but I didn't even bother to look at it because thought this would be a complete disassembly. This is a great lead. Am unable to now but will give that a try ASAP. So I guess it makes its connections simply by being slid in. I've tried gently pushing it in in the event that something came unseated but this will give me a better look at what is going on there. That rear hole on the drive looks like a screw hole but I can't see how it would go far enough back to hit that mid-mounted screw on the bottom.

Ha! That worked! Removed three screws, slid drive out and back in (not expecting anything to happen since I had already tried to "seat it" and got nothing), replaced screws, drive shows up in file explorer and BIOS, no longer grayed out no code 45.

You saved me hours of time not having to reinstall OS and frustration from doing that and having the same problem. You are the "laptop master" and "Acer authority."

Thank you very much for your time.
