I did some fiddling and it isn't the SD card. It also appears that the plugin is not recognizing the size of the SD card (256 MB). With the drag and drop window open, I noticed MC only shows the internal memory remaining in the PDA (15 MB). If you drill down through the directory structure to the SD Card in MC 9 (left pane), it does not update or change the size value. The iPAQ 2215 uses PPC 2003, I don't know of that is a difference for the plugin you developed.
I also tried copying a small file, such as a cover art JPG, thinking maybe it was just not relaying the size information correctly to the plugin. However, if you do like you described in your previous post, once you hit the transfer button the transfer progress dialog window comes up, but then so does an additional empty error window with no text in main dialog window (just red "X"). The title on the top of the dialog window is "h". Nothing else. It then proceeds to hang at the "Device Transfer Progress" box and you can not cancel out of the transfer. MC still works but the transfer box can not be canceled unless you exit out of MC completely.
So in summary:
1) I can add/delete folders within the SD card through MC
2) I can delete any files on the SD card through MC (that I previously copied through Windows XP explorer). So MC does "see" the card contents, etc.
3) The plug in works fine when transferring to internal memory of PDA (not workable though with only 15 MB).
4) Plugin hangs when copying smaller files (such as JPG file) to the SD Card path with an odd "h" error dialog window.
5) I uninstalled and reinstalled the plugin. No change. I am using plugin version 9.0.05. MC is version 9.1.316. It is on a Windows XP box..with all current patches/updates..etc.
6) It isn't the card or some glitch of the connection to the computer. I can copy fine through Windows to the card via Windows Explorer, and like said above, MC does see the directory contents of the card. I need to see if I can borrow a Compact Flash card and see if it does it on that as well.
Thanks,
