Xubuntu 14.04. nfts-3g is installed.
/dev/sdc is the Flash drive. I have created new partition with fdisk (tried with cfdisk too). Tried with W95 FAT32 code and W95 FAT32 (LBA) code. ("b" and "c" in fdisk).
After writing the changes I try to mount it with:
mount -t vfat /dev/sdc1 /media/flash4gb/
mount: wrong fs type, bad option, bad superblock on /dev/sdc1,
missing codepage or helper program, or other error
In some cases useful info is found in syslog - try
dmesg | tail or so
dmesg says:
[60591.890070] FAT-fs (sdc1): invalid media value (0x73)
[60591.890077] FAT-fs (sdc1): Can't find a valid FAT filesystem
NOTE: Usually the other software like: USB bootable USB creators working well. After they touch the drive, everything is fine. I am not sure FAT32, but the NTFS is well.
