[maemo-users] Memory card recognization issue in OS2008

Thanks, Mark.  No, the cards are writeable.  As noted earlier, the 128MB
card worked until the system rebooted following a backup restore and I had
copied the backup data onto the 128MB card from data copied from the 2GB
card (which I copied over to my Vista system).  Boy, that was a mouthful.

I am seriously considering reflashing.  What's the worse that can happen - I
spend a few more hours re-installing software...

I would try reflashing the OS, in case your last flash got corrupted.
If that doesn't work, it's not sounding promising for the hardware.

You have made sure that the little write-protect switches on the cards
are in the unlocked position, right? Some readers ignore those
switches, though, and I had one reader that malfunctioned and always
reported the card was write-protected when it wasn't. I thought the
card itself was toast, but I got a new reader and the card worked fine
thereafter. I hope the same thing hasn't happened to your Nokia.
