Need help with DVD-RAM on UJ-825 ("Superdrive")

Recommended Posts

Hello,

 

I got a big problem trying to backup to dvd-ram. The device is listed as qualified in the database, and DVD-RAM media are explicitly listed as supported.

But retrospect does not erase the media, configuring attempts result in errors. According to some error dialog retrospect recognized a "CD" medium.

The burner works fine with media of other types, and Disk Util recognizes dvd-ram as read-only (normal).

All Software (MacOS, Retrospect) is latest versions. How can I get the backups to work?

 

 

Retrospect Version: 6.1.126, Retrospect Driver Update version 6.1.4.103

 

Burner: MATSHITA (Panasonic) DVD-R UJ-825, Firmware DAM5, via ATAPI in an Apple G4 Powerbook

 

Tested Media are Verbatim DVD-RAM for recording, #43449, 3x certified, 4,7GB; Panasonic DVD-RAM Disc, 3x speed DVD-RAM Revision 1.0; Fujifilm DVD-RAM 4,7 GB.

 

Thanks for any suggestions!

Hi

 

When you create the backup set make sure you choose "removable disk". DO NOT create a CD/DVD backup set.

 

You may need to tell Retrospect to ignore the device in configure->devices->device status in order to use DVD-RAM.

 

DVD-RAM and DVD are completely different media types.

 

Thanks

Nate

Hi, Nate!

 

Thank you for the fast response.

I have followed both your suggestions but failed to get a result with a test backup: "No removable media found". frown.gif

Hello, Natew and all,

 

I have done some further testing, following Natews suggestions (Ignore Device ID, Removable Disk), on a clean system install (10.4.0) to exclude possible other causes.

 

Of 3 blanks from different manufacturers, only the Panasonic blank gets mounted on the desktop. But in Restrospect it appears "write protected". It is the only one of the three showing a format (UDF) in Disk Util.

 

Could it be that Retrospect *requires* pre-formatted UDF blanks? And that it has no own capacity to override a write protection? Or is the write protection caused by the missing DVD-RAM write capacity of the Finder -- why would a manufacturer sell blanks as write-protected? How would I enable Retrospect to write to and format a DVD-RAM?

 

Still trying,

Sam
