Welcome to the Forum!
Need more info:
Is this a new/newly installed burner? If not, has it always ripped/burned slowly?
If it is new:
1.) Did it replace another CD or DVD drive? Make sure you have a modern IDE 80-conductor cable plugged in to it from the motherboard.
after that has been confirmed/corrected:
2.) Click on START>right click on MY COMPUTER>click on PROPERTIES>HARDWARE (tab)>DEVICE MANAGER>double click IDE/ATA/ATAPI CONTROLLERS:
Double click on PRIMARY IDE CHANNEL>ADVANCED SETTINGS (tab):
Make sure device 0 & 1 are NOT set to PIO mode.
Select DMA WHEN POSSIBLE in the Transfer Mode boxes on both devices 0 & 1.
Current transfer mode should now read: Ultra DMA Mode 1,2,3,4 or 5
Then, do the same for SECONDARY IDE CHANNEL.
Now, restart your PC for the changes to be permanent.
If this doesn’t work for your device (stuck in PIO mode), right click on the ide channel it is in (1 or 2) in the Device Manager & select uninstall. Windows will ask you if you are sure-click yes. Now, restart your PC & Windows will automatically re-install the IDE channel & the devices (drives) on that channel. You’ll see Windows ‘detecting “new” IDE channel & devices’. Once rebooted, reboot a second time, then check in Device manager under IDE/ARA/ATAPI controllers, etc… like before & see if your drive is NOT in PIO mode anymore.
This worked on one of my optical drives, but the other one would not come out of PIO mode. It turns out on my Dell PC, the second drive (device 1 on primary IDE channel) was turned off - not in Windows, but in the BIOS primary IDE channel.
I hope this helps.
