terrimw Posted October 22, 2009 Share Posted October 22, 2009 I am new to this, so sorry if this is a really dumb question. My drive is an HP DVD Writer 840b ED56. I found something that said the OEM is LG, but when selecting this book type the current setting field says: Unknown (FAILED!) Reason: Invalid Command Operation Code Any help would be appreciated. Thanks! Link to comment Share on other sites More sharing options...
LIGHTNING UK! Posted October 22, 2009 Share Posted October 22, 2009 Either the drive just doesn't support the commands then or your drivers are blocking them. This is common if the drive shows up as '(SCSI)' or '(RAID)' in the disc info panel on the right. Link to comment Share on other sites More sharing options...

Cynthia Posted October 22, 2009 Share Posted October 22, 2009 Do you see SCSI or RAID in the log? Like this example I 15:06:27 Destination Device: [6:0:0] PIONEER DVD-RW DVR-216D 1.09 (H:) (SCSI) Link to comment Share on other sites More sharing options...

Cynthia Posted October 23, 2009 Share Posted October 23, 2009 It's a re badged LG GSA-4166B, so if the commands fails for LG the first words in post #2 is the issue. It seems it's possible to flash it to a "genuine" LG - but the warranty will be gone and also the drive might be harmed. http://www.videohelp.com/forum/archive/hp-840b-broken-t305893.html Another option is to replace it with another drive. The log you posted from the TSSTcorp DVD+-RW TS-T633A drive shows that it was book typed to DVD-ROM. Link to comment Share on other sites More sharing options...
LIGHTNING UK! Posted October 23, 2009 Share Posted October 23, 2009 I'm confused... do you have a TSSTcorp drive or do you have an HP one?! Post the disc info for the HP drive as that's the one you're having issues with! Link to comment Share on other sites More sharing options...
