larrymcg Posted August 6, 2006 Report Share Posted August 6, 2006 I have a backup set on CD-Rs mostly written by an old CD-RW drive. I have replace that drive with a new DVD write (dual format, dual layer, 16X,...). Today I tried to restore a file from CD-Rs that were written by the old drive. Retrospect asked for a specific disk and when supplied it took a look at it and decided that something (the drive, the CD?) was incompatible. Is there a requirement that the disks be read by the same drive that wrote them? --Larry I'm using Retrospect Pro 6.5.382 although the disk of interest was written by an somewhat earlier 6.5.xx version.

nekr0phage Posted August 9, 2006 Report Share Posted August 9, 2006 Hi Larry, If it is possible it would be best to use the same burner to restore. If a custom driver was created to use a particular burner, the likelihood of being able to restore that data with a different burner is rather low. You could try running a custom configuration for the new burner with the same media that you had previously backed up with. This might allow Retrospect to properly interact with that device/media combination. Link to comment Share on other sites More sharing options...
larrymcg Posted August 9, 2006 Author Report Share Posted August 9, 2006 Foster, Thanks for that news (bad news as far as I'm concerned). I'm absolutely flabberghasted that this is (might be) the case. Indeed I had to do the custom configuration for the DVD writer since it isn't one of the (seemingly few) natively supported by Retro 6.5.xxx. One conclusion I get from this is that once you do a custom config with one media type, you have to keep using that type and maybe only that type. That is simply not acceptable. Tell me it isn't true! --Larry Link to comment Share on other sites More sharing options...
nekr0phage Posted August 9, 2006 Report Share Posted August 9, 2006 Larry, Unfortunately that is true. When performing custom configuration you are telling Retrospect to build a custom driver for the devices. The custom drive will only support media types that it succesfully configures for. It is possible to configure for more than one type of media - at the end of configuration with a disc it should ask if you'd like to configure with any additional types of media, you need to say 'yes' and insert the next media type. You can configure with as many types of media as you want to, but they all need to be done at once so that they load in the same custom driver.

larrymcg Posted August 10, 2006 Author Report Share Posted August 10, 2006 I'd like to have a definition of "media types". Does that mean different brands of CD-Rs? Or does it mean CD-R vs DVD-R? Thanks, Larry Link to comment Share on other sites More sharing options...
nekr0phage Posted August 18, 2006 Report Share Posted August 18, 2006 Hi Larry, The definition of media types I use includes both brand name and format type. So a GQ 8x DVD+R would be different from a TDK 8x DVD+R,in addition to the obvious differences of CD vs. DVD and DVD+ vs. DVD-. Link to comment Share on other sites More sharing options...
