I recently bought a
Hama USB multi-format card reader, as I own a variety of older cameras that use Compact Flash, SmartMedia, FujiFilm xD etc. It works well generally, but I'm running into a (thus far, minor) problem when using it with Compact Flash - specifically, a Cisco 256Mb Type II card (I haven't tried it with any others yet).
I insert the CF card into the reader, then plug the reader's USB cable into my laptop. The reader appears as drive "D:" on my system. I navigate to the photos (in this case, they're TIFF files), double click on one to open it with Windows Photo Viewer, and the photo displays as expected. Now, if I click the window close (X) button to close the viewer, it closes the
photo but not the
application, which - after a short period - displays "(Not responding)" in the title bar. If I click the close button again, I get the following error dialog:
"COM Surrogate is not responding. If you close the program, you might lose information."
When I choose to close the program, the OS reports the problem to Microsot and then it closes.
If I now try to eject the D: drive by clicking on the icon in my system tray, I get the following error dialog:
"'USB Drive [D:]' is currently in use. Save any open files on this disc, and then close the files or programs using the files before trying again. If you choose to continue, the files will be closed, which might cause data to be lost."
If I continue, the drive is ejected.
I've repeated this process numerous times opening the same and different files on the CF card, with exactly the same results. There doesn't appear to be any damage to the files, but it's a little concerning nonetheless.
Even if I don't use Windows Photo Viewer and instead simply copy the files from the reader to my laptop's main drive, when I come to eject the D: drive, I get the error message above.
This only seems to happen with CF cards (or, rather, the one CF card I've tried). When reading SD and xD cards, it works perfectly.
I'm running Windows 10 (10.0.19043, build 19043), and the reader doesn't use a proprietary driver. I get the same problem using a second laptop with the same OS build.
If any of my fellow members have experienced this and can offer a solution, I'd be most grateful. Alternatively, any ideas or pointers would be just as welcome.
Thanks in advance!
