Hi All,

Looking for some help here from a very unusual problem.

I have a Plextor 716-A DVD drive in my machine that's running Windows 7 32-bit, ASUS P5Q deluxe MB and 2 x SATA HDD's.
The DVD drive is not found by Windows on start-up, it does not appear in My Computer or in Computer Management - basically Windows knowns nothing about it.

The DVD drive is found in the BIOS and I can see it's being loaded during boot-up. I can use the drive as a bootable drive.

The drive is only discovered by Windows when I enter and then resume from sleep mode or hibernation and works fine.

I've gone through every article I could find on the Web from Mr Fix it to the Upper/Lower Filters regedit.

Any ideas?

I mean I can see the device was found before windows starts loading i.e. just after the BIOS screen (the BIOS Post screen)

I contacted Plextor and it looks like this drive isn't supported by Win 7 - think it's time to bin it!

That doesn't really make sense. Whether the drive works should not depend on the OS involved. It is a generic Windows driver.

You know, right, that by default Windows 7 does not show empty drives?

But if you do get a new drive, please let us know if the problem went away. There may be some strange reason that the drive doesn't work in 7 (which means it couldn't work in Vista, either).

The drive didn't show on the Windows 7 compatibility list either when I was installing the OS. Since the drive works when I resume from Sleep I'll probably hold onto it until I really need to upgrade, not ideal I know. I rarely use the drive anyway.

Well, it's your business, of course, but I thought I should say something so you didn't end up in the same boat with a new drive.

Just for the heck of it, in Control Panel > Folder Options > View, is "Hide Empty Drives" checked?

Good luck.

Yes that option was checked, I unchecked it but the drive did not appear - thanks anyway for your suggestions.
