I've already done a fair amount of research on this, but no much luck so far.
My LG BT10N (Panasonic UJ-240 in an enclosure) is rated to burn at 4X for BD-R DL and 2X for BD-RE according to http://www.lgsolutions.com/products/digital-storage/optical-disc-drives/blu-ray-drives-slim.
Whether I use Nero (verify disc is unchecked) or Windows drag and drop it takes around 5 hours to burn one disc. My calculations support http://en.wikipedia.org/wiki/Blu-ray_Disc_recordable, which says 48mins for 4X!
The disks I bought are TDK BD-R 50GB DL Ver 1.3 1-6X, and TDK BD-RE 50GB DL Ver 1.3 1-2X.
I've loaded up ImgBurn, and it reports:
State of Last Session: Empty
Free Sectors: 24,438,784
Free Space: 50,050,629,632 bytes
Free Time: 5430:52:34 (MM:SS:FF)
Next Writable Address: 0
Supported Write Speeds: 1x, 2x
So clearly,I'm not going to get anything fast out of that programme either.
I am burning from external 1.5TB Seagate SATA drive to the burner, both of which are USB 2.0. However, the bottleneck remains with the Blu-Ray spec at 144Mbps.
I ran Nero Info Tool: http://www.thebreadcrumbtrail.org/ga...2_itemId=24095, but came up with same result
The only thing I can think to do now is buy some different discs, incase this was the issue. And if not, then I'll know it's the drive. Or update the firmware
Any suggestions welcome
