. . . there is a little switch on the sd card itself that will switch it to read only.
maybe obvious but easier to overlook. Perhaps yours has one too.
Thanks for the thought, but it isn't that.
I've since tried to reformat the disk back to FAT via the card reader on my PC, but that didn't fix it.
I've also bitten the bullet and reflashed to OZ 3.5.3 with Opie - I hoped it might have different (better!) drivers. The problem's still there, but now manifests as loads of spurious files on the SD disk. I think I'll just have to give this card up as a bad job, and try another manufacturer.
By the way, the card works like a dream on the PC!
