Slow Rip Speed?

[yeeman15]

My Lite-ON LTD 163 (DVD-ROM)has recently started to rip DVDs at a much slower speed (max 1.8x). It used to rip a DL disc in around 20 minutes; now it takes around an hour. I'm using the newest version of RipIt4me, however ripping a disc with dvd decrpyter by itself is also slow(still 1.8x). Can anyone tell me what happened? Fixes? Thanks

The reader may have reverted to PIO mode.

To check DMA/PIO mode within Windows:

Control Panel>System>Hardware>Device Manager>IDE ATA/ATAPI controllers.

From there, right click on one of the channels and choose 'Properties>Advanced Settings'. All drives should be DMA mode. The 'Current Transfer Mode' for Hard drives is usually DMA 4-6 and DVD burners DMA 2-4, DVD ROMs usually DMA 2. If you see any in PIO mode, that can slow things down.

Changing them back may be easy or complicated. First see if you can change them in that window. If not, I usually uninstall the channel the drive is on and let the OS reinstall it. This will usually take a reboot. This will not damage any files on the computer.

From there, if no luck, get back to us.

if everything you've done per redwudz advice and it still rips slow then the dvdrom maybe dying. it be a good time to upgrade to a new dvd burner since the cost of a dvdrom is about the same.

That was it Redwudz thanks

You're welcome. Just for future knowledge, if Windows has 6 read failures in a row of any drive, even a hard drive, it will automatically revert to PIO mode, after trying some slower DMA settings. Unfortunately, it won't reset automatically, and it won't alert you to the problem.

It's a Windows 'feature' of some questionable value that allows a drive to continue reading at a slower speed. If you are having difficulty reading a disc with a drive, and from then on, it reads and burns all discs slowly, and it uses a lot of CPU power to do it, PIO mode is the first suspect.
