Hi all. This is a sad story... :sad:
For my backups I 'm using Verbatim LTH BD-R single layer
So far I have experienced this:
burning is ok, playback is ok, but after some months (about 5-6 months) disk is not playable anymore.
To check my BD-R I've tried copying them to hard disk. It tooks a bit but apparently I succesfully copied the content of the BD (BDMV and Certificate dirs) to hard disk simply with a copy and paste.
After that I executed clownBD on the BDMV folder on the hard disk and....eac3to it's complaining about source files damaged!!
The source file seems to be damaged (sync byte missing). <WARNING>
The source file seems to be damaged (discontinuity). <WARNING>
So just copying from BD to hard disk without any error message is not enough to be sure BD content is good???
Also... I have verified the BD with imgburn and it didn't report any damaged sector... it took a lot of time to complete and speed degraded a lot for the last 10% (start at 2.48, finish at 0.3) but no errors reported...
Same happened using nero scandisk. read speed degraded but it didn't report any damage/defect.
So now I'm stuck... What am I missing?
P.s: I'm very disappointed about this degradation on verbatim LTH. What do you think about? And what do you advice? I'm thinking about conserving backups on hard disk and burn cheap mediarange when children or friends want to watch movies.
Thanks all for your suggestions/explanations
