Did you have a number of folders listed in the folder list box? Each of them would indeed need to be scanned.
Every time I began an ingest I only had one card in the multi-reader so only 1 drive was reported. It reported a drive and not a volume IIRC. I wonder if I had previously selected several directories that are no longer available and they were cached and it hung up looking for them - like clicking on your "A:" drive in Windows Explorer with no floppy in or if there was actually no "A:" drive. In any event I can attest that it took between 3 and 5 minutes to get to the dialog (dual processor 4200+ 1 GB Mem). It was definitely getting hung up doing something. If necessary I would be willing to run a debug version or generate a log if this is a known issue and you wish to pursue it.
If you ever want to process a large number of photos that are already on your hard drive then Ingesting Folders is the only way you can do that without Ingesting the entire disk.
I suspect that is exactly how I subsequently ended up with ingesting volumes.
It unmounts the volume from the file system. I suppose you could say it "ejects" the disk but that term is usually applicable to CD-ROMs or DVD-ROMs.
I wasn't sure if that was the same thing as the "Safely Remove Hardware" in the (windows) system tray. That's handy.
Thanks again for the response. I have my solution and really enjoy the product and have enjoyed watching it evolve over time. The performance enhancements have been commendable. Again, if the particular issue I reported is of interest I would be more than glad to help debug it. It is really, really slow on my system for some reason.
