I cannot copy any files to the SD Card (1GB) using a SD Card reader (TravelLite from Kingstone). It says the “Cannot copy xxxx file. The Disk is write-protected. Remove the write-protection or use another disk” message. SD Card is not locked.
I read many forums and newsgroups. Solution is nor software nor strictly hardware related:
put a piece of tape over the switch on the sd card and it will work. It worked!
