A bit of backstory:
I upgraded to a laptop with 32-bit Vista in April 2007, and then to a desktop with 64-bit Vista in August 2007. DVDFab always worked fine on my laptop with its DVD burner. However, I never could get it to recognize either of my burners on my desktop. Thinking this was likely a 32-bit vs 64-bit issue, I hunted around for 64-bit ASPI drivers, etc., etc., etc.
To make a long story short, I never could get DVDFab to work on my desktop. If I came across a disc I could not backup using DVD Decrypter, I would bring it over to my laptop, then transfer the resulting ISO file back over to my desktop.
A couple of weeks ago, I reinstalled Vista from scratch on my desktop (I’ve been playing around with vLite). Hoping that perhaps something had been changed or fixed, I installed DVDFab again. Lo and behold, it worked now! I did a test rip of one of my movies, worked fine, etc. Awesome!
I went about configuring my fresh OS install with my usual complement of software and settings. A week later, I fire up DVDFab again… and back to the old problem of not recognizing either of my drives! Application conflict? Driver conflict? Something that I had removed with vLite? But why did it work at first, but not now? And yet it continues to work fine on my laptop (also with a vLited Vista install)!
After more head-scratching and quiet meditation, I figured it out: DVDFab 5 (including 18.104.22.168 beta) appears to ignore the A: and B: drives (bolded for those who want to cut to the chase ). Since I have no floppy drives on my system (haven’t touched one in years, and have no intention of ever touching one again!), I assigned my two burners as A: and B:. Upon reinstalling Vista, the drives went back to their default assignments (J: and K:, or something like that). DVDFab worked fine like that. When I reconfigured things to my liking, I switched drive letters around, created additional volume mount points (I have a lot of drives), etc.
It works on my laptop, because the DVD burner there is F:. Yet all my other DVD-related software recognizes A: and B:… Windows Explorer, DVD Decrypter, ImgBurn, Nero DiscSpeed, DVD Shrink, DeepBurn, etc.
I’m thinking that for some reason DVDFab is hard-coded to ignore A: and B: as potential optical drives, when it really ought to be scanning down the list of devices, without discriminating based on drive letter. Can anyone else test this out to confirm? I’m going to try this on my laptop next.
