Blu-ray Forum - View Single Post - Backup onto dual-layer BD-RE

I have a new (Philips) PLDS DH-4B1S Blu-ray drive that is stated to be compatible with 50GB dual-layer BD-RE discs. I am trying to use it as a backup drive for a PC, and it keeps giving me media data integrity errors.

My PC is a Dell server workstation running Windows XP Professional. The Blu-ray drive came configured for this PC from Dell.

The backup software is Backup MyPC v4.85 (a 6-year-old old and possibly discontinued application that has served me well with DVD+RW discs). It does recognize the BD-RE drive.

The backup media is Panasonic 50GB BR-RE, part #LM-BE50DE.

I specifically wanted the ability to write to dual-layer media, due to the size of my backup jobs.

When I run the backup job, it completes successfully, but when I then verify the data to ensure a successful backup of all files, I get a number of errors that say either...

Error: <file name> has damaged or corrupt data on the media. Compression information mismatch [4886 1316]

or...

Error: <file name> has damaged or corrupt data on the media. File header not found on media [4872 1308]

I'd say it's much less that 1% of the files that show errors like this, but that's more than enough to make this application useless as a backup strategy.

I can't figure out if the problem is due to bad media, software issues, write speed (I see no way to slow it down), or with the burner drive itself.

Any ideas, or suggestions for troubleshooting? These discs are too expensive to go experimenting with various discs, at US$47 per disc, so I'm wary to open another one to try, before I've exhausted other options.
