Backup software always ask to erase DVD+RW: Pioneer DVR-109

Postby Patrice Brousseau on Mon May 16, 2005 10:54 pm

Hi,

I got a brand new Pioneer DVR-109 last week. It is working well in Nero,
CDBurnerXp Pro and another freeware burning applications.

It works well too with Image for Windows 1.51 except for one thing: when I
use DVD+RW that were erased with any of the already mentioned applications,
Image ask me if "I want to erase media". Of course, I answer yes and there
is no problem doing the backup and validating the image.

Strangely, if I insert one of these erased DVD+RW in other burning
program, none of these warn me that I must erase the media. However,
CDBurner XP Pro gives me the info (in the media property page) that the
DVD+RW was closed last session.

Please note that I tried with 2 brand of medias: Mitsumi and Sony, all of
them 4x DVD+RW and that I have the latest firmware for my Pioneer.

I also tried to format with DVDInfo Pro: same behavior in Image for Windows.

Thanks a lot.

So the "Image for Windows" software requests an erase regardless of the RW media's current state? Probably a 'bug' in the software. ( or a "feature" ) :P

Well, after extensive testing it appears a little more complicated.

With Image for Windows software: if I put an unerased DVD+RW to make the backup, Image erase it but in the image ends corrupted. Reproducible 100% anytime with two brands of medias.

However, if I erase the DVD+RW's with Nero or DVDInfo Pro, the image and the validation remains ok. Also reproducible 100% anytime.

Just to be sure, I made the test only with Nero: without erasing the DVD+RW, I started a new data disc (4GB of data). Nero warns me about "all data now present will be destroyed" and burned the data with the option "verify after burn". Oh well, an error occured on one file that is unreadable... Bad media, bad burner...?
