Is the card that is not showing up under Linux formatted as NTFS? Depending on your distro, you might not have support for that out of the box.

One Linux recognizes just fine when I use a flash card reader in the USB port. The other Linux does not recognize at all. Generally such media shows up as /media/usbdisk, but NOTHING shows up in /media with the card that Linux doesn't recognize. They are the same brand. The only difference I can think of is that the one that Linux does not recognize was written to under Windows. I can't remember if it was XP or 7.0, but it was one or the other. Windoze 7.0 will happily recognize, read, etc., the card that Linux will not. Any ideas what's going on? I'd like to move some of the junk--er, highly valuable data--from this card to my Linux HD. Not to mention just understand what's happening. Thanks. Howard Sanner linux-au...@terrier.ampexguy.com
