LG DVD-RAM Drive not reading discs in Windows 7

Anonymous

Title pretty much sums it up....

I have 7 installed and it's running great! But if I put anything into the drive to load onto the system it doesn't spin it up. I can see the drive in My Computer, but it still thinks that CD1 of World of Warcraft is inside of it, but it didn't spin up that disc either.

I had a bunch of things turned off during the install (HyperTransport, IDE, FDD), should I turn everything off again and try to load it up, just to turn it all back on later? Or is there a known fix? Exact model is the GH22NS30.

AMD Athlon 64 x2 Dual Core Processor 5400+ Black Edition; Abit AN52 nForce 520 Motherboard; OCZ SLI-Ready Edition 4GB DDR2 (PC2 6400); Western Digital WD360GD 36gb Raptor; Western Digital WD740ADFD 74gb Raptor; LG GH22NS30 DVD-RAM Drive; XfX GeForce 8800GT Alpha Dog Edition

Hi Rustedbucket,

Thanks for posting to the Getting Ready for Windows 7 communtiy forum.

Try deleting the filters in the registry, see if this helps to resolve this.

Remember to backup the registry to external media prior to editting the registry.

Click Start

, type regedit in the Start Search box, and then click regedit in the Programs list.

Collapse this imageExpand this image

If you are prompted for an administrator password or confirmation, type your password, or click Continue. 2. Locate, and then click the following registry subkey:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class{4D36E965-E325-11CE-BFC1-08002BE10318}

Caution There can be many instances of the registry subkey that is mentioned in step 2**. You must make sure that you are in the appropriate registry subkey before modifying the UpperFilters and the LowerFilters values. To verify that you are in the appropriate registry subkey, make sure that the Default data value is DVD/CD-ROM and the Class data value is CDROM**. 3. In the right pane, right-click UpperFilters, and then click Delete. 4. Click Yes to confirm the removal of the UpperFilters registry entry. 5. In the right pane, right-click LowerFilters, and then click Delete. 6. Click Yes to confirm the removal of the LowerFilters registry entry. 7. Exit Registry Editor, and then restart the computer.

Please let us know if this assists you or if further assistance is needed involving this issue.

Thanks for your suggestion.

but I tried it and still no luck.

I've pretty much given up on this matter.

it's clearly a win 7 issue, b/c if I switch system to win xp, DVD works just fine

Nearly two years since your post -- but I have had the SAME EXACT problem for months and just now got around to researching the fix. Tried everything listed here, to NO avail.

Then, I started inserting my whole library of CDs. One CD in particular loaded a screen that said something like, "This CD is formatted in Mt. Ranier *MRW* format, but your operating system does not appear to support it. Please download a third-party software such as InCD or click here to install it from this CD."

Well, I installed the InCD software, rebooted, and my LG DVD-RAM is now reading discs. EVIDENTLY not all CDRs, CDs, etc., are manufactured with this solution. So for anyone who happens upon this long thread, hopefully this will work for some of you.

P.S.

This from Wikipedia: "Mount Rainier is implemented natively in Windows Vista (2007). Linux has built-in MRW support sincekernel version 2.6.2 (2004).Amiga OS4 supports this natively since the first beta appeared in 2004. Operating systems that don't support MRW natively (notablyWindows XP and prior versions) need third-party software to read and write MRW-formatted discs, and these tend to be the samepacket writing utilities which allow native UDF filesystems to be written to optical media."

This solution totally worked for me. I upgraded from Vista Home Premium 32-bit to Win 7 Pro 32 bit and my LG hl-dt-st dvdrw gs20n ata stopped working all together. I did everything suggested here in this thread before I found the BIOS suggestion. I went to http://michaelstevenstech.com/bios_manufacturer.htm found the pc manufactuere. Now it asked me what OS I was running and I picked Vista cause there wasn't an update for Win 7. So, just for grins update your BIOS... what do you have to loose?

A big thanks to Obsoleet!
