I have a Flash drive accessory for my camcorder which allows me to record to it as well as the SDHC cards it also uses as media.
This Flash drive can be connected to a computer using a USB connection and is recognised as an external hard drive formatted as FAT32, containing a single AVCHD folder (containing the video).
I have my own external USB Hard Disk, formatted as Mac OS Extended (Journaled, Case Sensitive) and wish to copy my video to that drive for storage, so that I can clear the camera Flash drive for future use with my camera.
I copied the video by dragging it in Finder, however, the new copy will not open in QuickTime; instead a message box "cannot open" appears.
After doing lots of comparisons, I was able to see that the contents of both copies were exactly the same, with the exception that one file:
AVCHD/BDMV/INDEX.BDM had changed case (to
Upon renaming this file, Finder no longer associated the file with QuickTime, but if I copied the file, so that I had both INDEX.BDM and index.bdm, it worked correctly.
My question is: what is going on here? Why did the case of that file and only that file change during the copy? Why does QuickTime expect it to be one case and Finder another?
