I added a udev rule in /etc/udev/rules.d/75-persistent-vfat.rules just for fun to have a /dev/sansa device for the internal drive

SUBSYSTEM=="block", ENV{ID_FS_UUID}=="A0BD-5FE2", SYMLINK+="sansa", ENV{GENERATED}="1"

When mounting the drive, use sync option in fstab so that it copies in real-time, and you don't have to wait a ton either running sync or unmounting the drive.

/dev/sansa              /mnt/sansa      vfat    noauto,users,sync       0 0

Copying large amounts of files to the internal disk will overwork the poor little device, and segfault RockBox usually at some point. Just run an fsck on the VFAT block device, and keep going. For the SD card that can go in there, use a modern card reader. :)

fsck.vfat /dev/sdf

Block size of a VFAT filesystem is 512k, so using rsync, you'll see it averaging around that speed limit.

Sometimes your filesystem is really jacked, and needs some rescue. See http://www.dedoimedo.com/computers/rescue-fat32-disk-linux.html

sudo ./fsck.fat -r -l -v -t -y /dev/sansa

Building RockBox from source isn't too bad … if you're patient. :)

Download 3.14 source code here and unpack it.

cd into tools/, and set proper permissions for executable files:

chmod +x *.pl *.sh configure genlang

Run configure, the architecture type is ARM.

Make a build dir outside of the tools directory, and run configure.

mkdir ../build
cd ../build
../tools/configure

The target for the Sansa Fuze is 58.

Run make as normal to build the install!
