I/O Error on LG GSA-H12N DVD drive on Windows 7

I am facing an I/O Error when I try to burn DVD data discs on my LG GSA-H12N DVD drive on Windows 7. Note that I was able to do this same operation on the same hardware/software just a day earlier without any problems, but with Windows XP. The only change (AFAIK) has been the installation of Windows 7 to replace Windows XP on this PC.

Here is the error I get when I try to burn a DVD data disc using CDBurnerXP 4.2.7.1801:

Burning error occured

An error occured while burning the disc. Most likely the disc is not usable.
Usually these errors happen if the inserted media is not compatible to the drive or of poor quality.

(devNTSPTI_IO_Error) Could not write to Disc (LBA: 52864 Length: 32).

SCSI Pass-through Interface I/O Error. - 0xFF045D

Note that there can be no problem with the discs since I have been using the same discs (from the same box) just before the Windows 7 installation with no problems. The only change has been Windows 7.

I tried InfraRecorder v0.5 and ImgBurn v2.5 and got similar I/O errors:

Note that Windows 7 lists the LG GSA-H21N drive as being compatible (see this link).

I also checked the LG Drivers website and using the firware update from there updated the drive firmware from version UL01 to UL02. But, even this has not helped. The drive reads DVDs without any problem, but continues to produce coasters.

Could someone help me figure out what is the problem? Thanks :)
