Can somebody show me how to make Gentoo mount my USB? This is what I got when trying mount /dev/sdb1 /mnt:
mount: wrong fs type, bad option, bad superblock on /dev/sdb1, missing codepage or helper program, or other error In some cases useful info is found in syslog - try dmesg | tail or so
dmesg says:
FAT: codepage cp437 not found
You need to set codepage and charset in kernel options:
make menuconfig -> File systems: -> Native language support: <*> Codepage 437 (United States, Canada) <*> NLS ISO 8859-1 (Latin 1; Western European Languages) -> DOS/FAT/NT Filesystems (437) Default codepage for FAT (iso8859-1) Default iocharset for FAT and then recompile kernel...
iso8859-1 and 437 differ for different regions. It seems that you do not have the "codepage cp437" support in the kernel.
Try to Look inside your /proc/config.gz file and search for a line like CONFIG_NLS_CODEPAGE_437=m or CONFIG_NLS_CODEPAGE_437=y. If you do not find it, you'll have to recompile the kernel to add the needed module.
FAT: IO charset iso8859-1 not found First, make the mountpoint:
$ mkdir /mnt/udisk Then, mount the USB drive, specifying the filesystem:
$ mount -t vfat -o defaults,utf8 /dev/sdb1 /mnt/udisk If it were NTFS, you could use:
$ mount -t ntfs-3g -o defaults,utf8 /dev/sdb1 /mnt/udisk Or for ISOs:
$ mount -o loop diskimage.iso /mnt/iso
