You might consider checking out your mail client. What you see above is the [text/plain, 7bit, iso-8859-1, 0.4K] version which, I think you'll agree, doesn't make a lot of sense as the most important line is missing. I could read that only from the [text/html, quoted, iso-8859-1, 2.7K] version. I don't know the type of card reader(s) you're using. My tiny ?µSD cards either fit in a USB2 device that's not much larger, or into hollow SD-size cards. All of the latter have a readonly slider. Is each µSD in its own adaptor, or are you using the same one for all? Cheers, David.
