Here are the results of my scans of the Made in Taiwan DataLifePlus Verbatim 1-4X DVD+RW disc, MID MKM A02, using Nero CD-DVD Speed to create the data disc and then Read Transfer test followed by the default PxScan batch file scan. I tried to fully erase the disc prior to the data burn but Nero stopped pretty quickly with an error message. Why?
Results are ok but not as stellar as with the DVD+R's I have scanned sofar, but I anticipate that is the norm when comparing rewritable discs - they just aren't as error free. I have read somewhere in this forum that the RW's error rate may improve on the second burn but then steadily deteriorate after that. Don't understand why that may be unless the first burn was on a fresh out of the wrapper RW disc, not fully erased before first burn, since I assume that an erased RW would also show deterioration in the "erased" quality similar to data on the disc degrading over time as well. I don't have any evidence to back this theory up, just the writer's anecdotal experience.
The real proof will be when I (try to) convert and burn an Xvid file to DVD format to play on a non-XviD supported DVD player, my initial purpose for using DVD+RW in the first place (along with harddrive backups).
