SD write protect indication?

[toga94m]

I've got a 2GB SD card with the slider write-protect switch thingy. Often when I insert the card, it drags on the slot and moves to 'protected' position. However, when I hit the pushbutton to force logging, the logging LED blinks cheerfully, indicating it's logging to the card. It's not until I get back to a PC and try to download the data that I learn nothing was recorded on my test drive.

Could the logging LED blink differently, or not at all, if the write-protect slider is on? Or should I just epoxy the slider into the 'enabled' position - fix it in hardware instead of software?
