No, I have another adapter, but 1) I can't find it at the moment and, 2) it came with the Transcend micro SD card that normally lives in my phone and, when it first arrived ~ six months ago, I tried it with its adapter in the laptop and it was also read-only. At that time I didn't follow up on the issue because I intended to use that micro SD card only in the phone, and it worked fine there. However, there is a note on the Thinkwiki that some adapters are flaky. It is entirely possible that both adapters are bad. But if that were the case I would expect that the card wouldn't mount at all, or mount but suddenly disappear, or give corrupted reads and writes or something, not that they would always uniformly mount read-only. But what do I know? Oh wait ... I do know that this adapter has some peculiarities. One of the connectors looks like it has a tiny bit of a curve to it, two of them stick out 1/32 of an inch more than the others, and the gap between the rightmost two of them is narrower than the others. Not a sign of good manufacturing quality control. I suppose I should google on what each of the pins does. But figuring out what the effects might be for each pin's failure sounds like a lot of research. _______________________________________________ PLUG mailing list [email protected] http://lists.pdxlinux.org/mailman/listinfo/plug
