That's why I like to use the /dev/fs entry in the fstab. I'd prefer the GPT label, but I'm stuck with an MBR drive. The system knows that it is not NTFS, but I'm guessing that it has no tools to recognize exFAT. Que sera sera. Thanks or the pointers to Wikipedia. I've read and used the GPT page a lot, but never thought to look for MBR information, though I should have. -- R. Kevin Oberman, Network Engineer, Retired E-mail: rkoberman@gmail.com
