Yes, that would be explained by the second part of my post: weird partitioning or formatting, with "weird" meaning something that the PC doesn't understand. In your case, the PC did see the card, it just couldn't read the file system and so nothing showed up. You would still see the card if you looked into XP's disk management tool, it would show up as a disk containing a partition of unknown type.Not true in my case. With the camcorder attached to the computer, the computer could read the internal flash memory but not the SDXC card in the second slot. Upgrading Win XP to read the exFAT file system did allow the computer to read that card too.
If you want to make sure that the SD card can be read pretty much anywhere, format it as plain old FAT32.
