Bing: how did you solve the "ioatacontroller device blocking bus" issue when booting to your SATA drive?

# Acidrain9

i set my hard disk as an external disk when i first installed leopard. you can use the cable nfoav8or mentioned previously in this discussion. after installation, boot into leopard still using usb <a href="http://www.tigerdirect.com/applications/SearchTools/item-details.asp?Sku=ULT40112"> cable</a>, and follow this

nfoav8or@bingtheone:

I GOT IT WORKING!! (well almost completely... all except audio)

here's how I did it:

First off, I got it just as far as you did with the safe mode and then had to transfer from another Mac volume. This seemed to be the only way to not get hung up at the same point as you so I transfered files/info from a "volume" that was simply another external HD that I installed to before the external SATA HD. After I was through this stage, I used the downloaded <a href="http://forum.insanelymac.com/index.php?act=attach&type=post&id=19616">kext</a> from earlier and unzipped it to the desktop. Now you should see the file AppleNForceATA.kext on the desktop.

Next I copied the file <b>Extensions.mkext</b> from <b>System/Library/Extensions/</b> to the desktop folder for manipulation. I manipulated the mkext file from here so that I wouln't lose sight of where the files were even though we'll be using the Terminal next. Because the mkext should be manipulated through your Terminal, make sure you use the bold commands to follow. (note, this was taken from another post in part... I claim no credit for this, just the will to bring it to you... also, make sure you know what directory you are running in when you do this so your work isn't lost to you. most times it brings you to your home folder when you first open Terminal so that's how I'll treat it.)

1. <b>cd Desktop/</b>
1. <b>mkextunpack -d Extracted /System/Library/Extensions.mkext</b> (notice the space between "Extracted" and "/System")
2. <b>rm -rf Extracted/AppleNForceATA.kext</b>
3. <b>cp -rp AppleNForceATA.kext Extracted</b> (notice the space between "AppleNForceATA.kext" and "Extracted")
4. <b>sudo chown -R root:wheel Extracted</b>
5. <b>sudo chmod -R 755 Extracted</b>
6. <b>kextcache -m NewExtensions.mkext Extracted</b> (notice the space between "NewExtensions.mkext" and "Extracted")

don't close Terminal yet, just minimize it (I know the following can be done in Terminal, but I am still new so I prefer to do it visually yet)

Move the old <b>Extensions.mkext</b> to the trash and rename the new file to <b>Extensions.mkext</b> (same as old one, of course)

drag this to the <b>/System/Library/</b> Folder
while in this folder, go into the folder <b>Extensions</b> and look for the file <b>IOATAFamily.kext</b>... right click, select <b>Show Package Contents</b> and navigate through <b>Contents/Plugins/</b> to see another file named <b>AppleNForceATA.kext</b>. drag the one from your desktop to this folder and over-write it.

--Now this is what screwed me up for a while...

You have to go back to Terminal and type:
1. <b>sudo chown -R root:wheel /System/Library/Extensions/IOATAFamily.kext</b>
2. <b>sudo chmod -R 755 /System/Library/Extensions/IOATAFamily.kext</b>

This should do it for you, but in case your computer continue to gets hung up... safe mode in again and search through the Extensions folder for any <b>NV*</b> or <b>GeForce*</b> files and delete them.

Reboot and I hope it works for you like it did for myself.

Cheers!

@ nfoav8or

I never got a chance to use the dvd burner... but i'll reinstall during this weekend and try to burn some dvds. (school begins again, kind of busy this semester.) i'll update how it goes.

@ BING

Ahh school. I remember back in the day... haha. well it wasn't <i>that</i> long ago for me. I've read that the support for Lite-On DVDRWs and TSS brand DVD-ROMs isn't that great for Hacintosh. I've read numerous posts of people with working Pioneer DVR212 drives so I bought one. However, I also bought a new external Lite-On so I could have DVD support as well and a new GeForce 7300 PCIe graphics card. All I've read are supported so lets hope its not too much work to get them to work with OSX... I am sick of being relient on windows.
Cheers all.

@ Bing

Thanks for the info. Running beautifully now.

Awesome Acid. can you post system specs? Thx and congrats.

just a "bump" to see if anyone has solved the SATA DVD problem? I am waiting on the new Pioneer to come in the mail. Just an update. I've decided to try and reinstall numerous times and every time I do, I am able to use my DVD drives UP UNTIL I input the AppleNForceATA.kext then they cannot read/write ANY dvds and/or cds.

Anyone... any ideas?
