[GRLUG] trouble mounting fat32 thumb drive

[Eric Beversluis]

I've got a thumb drive formatted as FAT32. It mounts (albeit slowly) and
works ok on  windows 7 boxes and mounts automatically on my fedora 17
box. But when I try to mount it on a clearos box (based on centos), it
won't mount: Tells me it "can't find a valid FAT files system on dev
sde."

[root at clearos mnt]# mount -t vfat /dev/sde /mnt/thumb
mount: wrong fs type, bad option, bad superblock on /dev/sde,
       missing codepage or helper program, or other error
       In some cases useful info is found in syslog - try
       dmesg | tail  or so
