There was a discussion about this awhile back. I think that you need to de-install from device manager, shut down, restart and allow the OS to re-discover. The drive got put into PIO mode because there were problems at DMA speeds. I am not 100% sure if this will work in Vista because the previous discussion concerned XP.
Sorry I'm stuck. It did work for me but I'm using XP. Did you check in the BIOS to see that DMA didn't get turned off somehow?
open up device manager and delete serial controler reboot computer os will reinstall the controler and drive will go to DMA
Had the same problem.. desktop crashed, burned & fried.. Was re-built (only able to salvage the case, 1 drive and a USB card), and the shop that built it for me installed 2 SATA DVD burners (1 lightscribe & 1 regular).. Couldn't get the lightscribe drive out of PIO mode.. checked the controllers, only found 2 that said IDE, one was set to DMA (my hard drives), the other didn't even have the option available.. Was going crazy till I found an old thread on Videohelp.com that talked about the specific lightscribe drive they installed in my desktop.. VideoHelp Post look for the post dated Jan 15, 2008 22:42 from BUDZ apparently the BIOS settings would not allow the drive to be set to DMA.. changed the 3 settings he listed and re-booted and now have both drives set for DMA... After doing so, the lightscribe drive immediately showed with DMA, but the non-lightscribe was suddenly showing up as a RAID drive.. a little more research found a link specific to my new MB and showed how to update the driver back to "Standard Dual Channel PCI IDE Controller" and now everything is working great... New MB is a Gigabyte GA-EP45-UD3P, so that "glitch" might not apply if you've got a different MB.
Ah, thanks for catching that. Now I remember I deleted the drive but had to delete the controller instead. You need to delete the IDE/SATA controller that the optical drive is connected to. Thanks for the clarification.
OK, this is what I have under storage controllers. Intel ICH8R/ICH9R/ICH10R/DO SATA Raid Controller ITE IT8211 ATA/ATAPI controller Microsoft ISCSI intiator The TSST Corp SH-S183L is a SATA drice. What I wonder is will my computer be able to boot up & get into Windows if I delete the Sata Raid controller? Also how do I get into the system BIOS to check there?
or "ESC" or "DEL" when you're booting.... depends on the MB.. usually if you're watching the screen during boot, there should be a key at the bottom of the POST screen (very first screen) that tells you what key to hit.. Goes very quickly though, so you have to be paying attention and hit that key very quickly... If you get to the Windows scroll bar, you've gone to far and you'll need to re-boot again.
