I am using the latest version of UltraIso with my Sony f121 laptop, the dvd rom model is Pioneer BD-Rom BDC-TD031 , I have lost 4 dvds but still can not burn my iso file (which is about 3 gig of size) . I have tested 2 models of DVDs and both are R+ , here is the log:
1# Windows 7 6.1 Build 7601 (Service Pack 1)
1# Recorder: (E:)PIONEER BD-ROM BDC-TD031.00
2# On the fly burning
2# Write Speed: 6X (8310 KB/s)
3# Media type: DVD+R
4# Number of blocks in ISO image is 1443154
5# Preparing media ...
6# Requesting burn at 6X speed
7# Error reserving zone for burn
8# Caching of files started
9# Caching of files completed
10# Burn process started, speed is 2.4X (3324 KB/s)
11# Burning process failed!
12# LBA: 544
13# Sense: KEY=04,ASC=44, ASCQ=4b
I have tried to burn iso, not worked, then extracted the data and burned on the fly, still not worked.
Any help would be appreciated.
