Hi,

I\'ve got a BenQ DW1640 DVD drive, but when I put a disc into it, until I reboot Windows it won\'t read it. For example if the drive is empty when I start up, it\'ll still think it\'s empty no matter what until a reboot.

Same if a full disc is in there, even if I eject it and change it, it\'ll still think the same disc is there. Quite annoying.

I was wondering if anyone would have any ideas?

I\'ve tried removing it in Device Manager and re-starting when it re-installed it, but had no luck there. I think the problem started when I un-installed Virtual CloneDrive a while ago now, but I can\'t be totally certain.

I\'m running Vista 64-bit, and have the latest firmware on the drive.

Thanks so much for reading!

I'm having the exact same problem! However I have an Optiarc AD-5200S.

If you find the solution to your problem, *please* post here I will do too. Nothing more annoying than threads which remain unanswered but still pop up in Google searches

Maybe there are some software similarities?

I'm running AntiVir, Epson printer utility, VIA HD audio deck, ATI drivers... otherwise it's just the usual Vista processes.

Edit: Just tried a different drive (same model, just a different drive from a different supplier) and it has the same issue.

Hrm. I flashed the drive to the latest firmware (v1.05 to v1.09) then rebooted, then it showed up as a "CD Drive" and the problem was gone (it read both DVDs and CDs even though it said "CD drive", by the way).

However after *another* reboot, it's showing up as a "DVD Drive", but now it has the problem again. The only way it'll recognise the fact that the disk in the drive has changed is if I reboot the computer.

Thanks for posting, and yeah you're so right about there being nothing more annoying than threads which remain unanswered but still pop up in Google searches!

I just tried disabling the sharing on my drive but that didn't change anything.

Sadly it sounds like we're running different software. I'm running McAfee, I have a Canon printer, a nVidia graphics card, and Creative X-Fi Sound.

Hmm :/

I'll certainly post if I find something though.

I found out I'm running AnyDVD, and when I close that, it works fine... except for burning DVD-RW :/ Nero 7 comes up with an error about not being able to start Disc-At-Once and fails to burn. DVD R's are all good though.

I haven't touched AnyDVD for many many months, so it's really strange that was the problem, but maybe it was a conflict with that and Virtual CloneDrive that didn't fix its self when I un-installed Virtual CloneDrive.
