GoMac Posted January 15, 2007 Share Posted January 15, 2007 Hi, I have a 2.5 year old 48x CDROM writer / 8x DVD writer, which under Windows takes about 4 minutes to write a full CD and 50 min to write a full DVD. Under Osx86, in 'best mode' it seems to write up to 5 times as fast! (CD: <2min, DVD< 10 min). The DVDs are readable in in Windows and I confirmed transfer of a full DVD to my PC. Anyone has any idea how this is possible? Could the writer be hardware limited under Win, and that OSX just bypasses this (as with the eject feature). Also I have the feeling that disks in general seems to work faster...

kjur Posted January 15, 2007 Share Posted January 15, 2007 normal time for burning full dvd at 8x speed is about 10 mins. check in your burning aplication under win if it burn with full speed. other idea: maybe windws hard disk is much slower....

Pitr- Posted January 15, 2007 Share Posted January 15, 2007 And also, make sure DMA-transfer is active for the cd/dvd-burner cause slow burning with older burners under Windows is usually caused by burners running in PIO-transfermode or problems with the IDE-controller-driver depending on what kind of motherboard/chipset you have.

GoMac Posted January 16, 2007 Author Share Posted January 16, 2007 Mmm, 10 minutes for a DVD! I use Nero on Windows and when I select 8X, it takes about 50 minutes. I will look into some of the hardware related causes and see if I can crank it up. Another indication that a 20 minutes plain install of OSX86 on 3 year old HW does a better job with it than Win2k. Thanks. Link to comment https://www.insanelymac.com/forum/topic/38778-my-dvd-writer-is-5x-as-fast-as-under-windows/#findComment-277261 Share on other sites More sharing options...

Thanks. Your burner isn't hitting 8x on Win, 50 minutes for a burn sounds more like 2x or 2.4x. And when you use nero, it reports that you're burning at 8x, but that's not an actual burn speed. There are some values you can add to the registry to show the current burn speed, but I can't remember those at the moment.
