AnalogueRock Posted July 21, 2007 Report Share Posted July 21, 2007 Hi I've been using Retrospect for about 6 years. Initally on an old PC, then on an iBook G4. This week I changed to a new 2.4GHz MacBookPro. On my new machine, I get an "Incompatible" error when I try and back up to DVD-R. It seems to work okay with CD-R, but that's not practical given the gigabytes of data I need to keep backed-up. I don't have any other types of media to hand to try it with. I'm running Retrospect 6.1.126 with driver update 6.1.11.101 on OS X Ver 10.4.10 on a 2.4GHz MacBookPro with 2Gb of RAM. System profiler reports my optical drive as a MATSHITA DVD-R UJ-857E. Normally it burns to DVD-R perfectly well (using either Toast or OS X). Am I right, therefore, in assuming that Retrospect just doesn't support my drive... yet? How long until it is supported? And what can I do in the meantime? Thanks & regards A-R Quote Link to comment Share on other sites More sharing options...
rhwalker Posted July 21, 2007 Report Share Posted July 21, 2007 The UJ-857E doesn't seem to be in the list of supported devices: Retrospect supported devices It also doesn't appear in the list of devices added by recent RDUs: RDU version history Oddly, the UJ-857D (Apple version) does appear to be supported as of RDU 6.1.9.102, but it is not in the database of supported devices. Only the UJ-857 (with no suffix) appears in the database of supported devices. Support for new DVD devices seems to take almost a year to appear, if ever.

Clive Bruton Posted July 22, 2007 Report Share Posted July 22, 2007 I think there's a possibility that either the Retrospect listings are incomplete, or that the specifications of the devices that have been added are wrong. As an example, I have a Pioneer DVR-112 - this is not listed as being compatible (the DVR-112D is), but Retrospect apparently uses the drive without a problem (prior to 6.1.11.101 I'd been using a custom .rdi file). The difference between these two devices is that the "D" model does not support DVD-RAM writing, where the model I have does - though I don't have any media to test Retrospect with DVD-RAM disks. So, it's possible that the drive you have may work with Retrospect with different media - try it with DVD+R? Quote Link to comment Share on other sites More sharing options...
AnalogueRock Posted July 23, 2007 Author Report Share Posted July 23, 2007 Yes... DVD+R worth a try... Just trying it now, and it's working! Thanks Clive, good thinking. Okay so it would be nice if it worked with DVD-R, because that's what I prefer... but frankly this is a perfectly acceptable workaround. The backup is running now. It'll be a while 'till it's complete. but I'll post back when I've tested it and 100% sure that it works. Many thanks! A-R Quote Link to comment Share on other sites More sharing options...
AnalogueRock Posted July 23, 2007 Author Report Share Posted July 23, 2007 Yes, the backup completed and verified successfully. All is well, cheers. A-R Quote Link to comment Share on other sites More sharing options...
rotozuk Posted July 24, 2007 Report Share Posted July 24, 2007 Interesting.. I was going to suggest that you have the 2 gig issue since you have 2 gigs of ram.. I wonder if + media works for those of us stuck with the 2 gigs of ram issue. Quote Link to comment Share on other sites More sharing options...

Actually, +R media will always work better with the packet writing that Retrospect does. -R is good for regular data (Toast, DiskBurner, etc). But +R is best for Retrospect.

AnalogueRock Posted August 9, 2007 Author Report Share Posted August 9, 2007 Thanks for the tip Dave. Am using +R now and I forgot I ever had an issue! SL Quote Link to comment Share on other sites More sharing options...
