Indexing CD and DVD

[pbaraby]

I have a dedicated database for all my original photos that are backup on CD and DVD. Since it was converted from 3.6 to Imatch 5, indexing a DVD take forever (over 20 minutes). Since I use this database only to find back an original file and on which DVD it is engraved, how should I configure this database to speed up the indexing?

The problem is the metadata extraction. Apparently ExifTool needs minute to load the data for only 7 files.
I don't know how to improve this speed, apparently your CD/DVD is averse to the way ExifTool loads data from files.

Probably it would be much faster to copy the DVD to your local disk, index from there, and then relocate the folder back to the CD.

Dealing with slow CD/DVD drives is usually not much of an issue anymore today. Even a 50 US$ USB stick can take the files of 100 to 200 CD's or 10 to 20 DVDs. A 75 US$ external disk holds the same amount data as 100 DVDs...

I have copy on external disk drives but can you explain me why I had no problem on 3.6?

IMatch 3 did not have support for all the modern metadata standards, had only support for a subset of the XMP and Metadata Working Group standards - and did not use ExifTool.

That ExifTool apparently brings your CD/DVD drive to it's limits is a small price to pay for the robustness, power and flexibility the inclusion of ExifTool in IMatch 5 gives us. I'm not aware of a way to make ExifTool faster when reading data from CD/DVD drives. I know it's much slower than from had disks (naturally) but at least with my Plextor and non-name CD/DVD drives I have not experienced something like 7 files per minute...may be a hardware/setup thing.
