I have a Thinkpad T520 (4239) that I just upgraded to Windows 8. I was not able to upgrade from a DVD; I had to use a USB flash drive to upgrade. I'm thinking maybe the problem was that the HLDS GT33N DVD drive did not have the latest firmware; it looks like its firmware version is LT20.
On the Lenovo Drivers and Software page for the T520, there is a DVD Firmware Update Utility for Windows XP, Vista, 7 (fwsb10.zip). The README does not mention Windows 8.
Can the utility be used on Windows 8? If not, when will a utility for Windows 8 be available?

If you do try it I would run it in Windows 7 Compatibility mode. The chances are higher that it will work. I have the same 4239 but a different DVD drive, Sony model and never release new firmware for it. I don't see why that would prevent you from reading a DVD it burned or OEM pressed DVD.

Thanks for the suggestion.
FYI ... using a DVD that I burned, the installation was failing with an 0x8007025d error code more than half way through the "Getting files ready for installation" phase. The error message said something like it could not install required files and that I should make sure the files are available. It didn't say which files it couldn't install and I assume that all of the required files are on the DVD. I'm pretty sure the DVD is not bad because the Windows 7 ISO burner utility verified the DVD after the burn. Sometime later I searched the Microsoft support site for the error code and found this article, which suggests upgrading the firmware of the DVD drive: http://support.microsoft.com/kb/930984 . Although the article is for a different operating system and DVD drive and the error codes are different, the error message is basically the same message that I saw.

Here is some research I found on supporting the DVD:

I decided to try to run the firmware update utility on Windows 8 in Windows 7 compatibility mode. However, there were no compatiblity mode options available for the fwwinod.exe application. I was able to set the compatibility mode on the DVDRAM_GT33N_Lenovo_TPG_LT23_LT31.exe.
When I ran the fwwinod.exe, it initially said no drive was found. The README file (fwsb10en.txt) stated that any media should be removed from the drive before attempting the firmware upgrade. However, if the drive has no media, the system seems to power off the drive, which causes the firmware update utility to not find the drive.
I was able to power on the drive from using File Explorer, and quickly launched the fwwinod.exe; it found the drive, but it said there was no newer firmware available.
I later ran the Compatiblity Troubleshooter on fwwinod.exe, but I wound up getting the same result.
If Lenovo ever releases an updated utlity for Windows 8, I'll try that version then.

I wish that had worked out
Since you're going to wait for the update, you can have the RSS feed inform you when it comes out.
This feed should keep you up to date with all driver updates.

Here it is nearly four years later and the only GT33N firmware update utility available is for Windows 7. I was about to do a clean install of openSUSE Leap 42.2 when I remembered that I never did update the DVD firmware from version LT20 to LT23. So, I wound up restoring Windows 7 from four recovery DVDs. Then I was able to update the DVD firmware. I also updated the Intel Management Engine firmware while I had Windows 7 installed. It was just frustrating that the firmware update, which should have taken no more than 15 minutes, took much longer because I had to reinstall Windows 7.
