I put it on a thumb drive because dd seems only to take devices not
directories. Do you know how to make an img from a directory?
To make an image from a directory (assuming the directory is named
raid_directory and the image should be named raid.img):
# Figure out how much space you need
host# du -ksh raid_directory
6M raid_directory
# Make an empty file a little bit larger than that
host# dd if=/dev/zero of=raid.img bs=1M count=7
7+0 records in
7+0 records out
7340032 bytes (7.3 MB) copied, 0.0836722 s, 87.7 MB/s
# Create a filesystem on it
host# mkfs.ext2 -F raid.img -L driverdisk

This filesystem will be automatically checked every 33 mounts or
180 days, whichever comes first. Use tune2fs -c or -i to override.
# Mount it via loopback
host# mount -o loop raid.img /mnt
# Copy the directory contents to the mountpoint
host# rsync -av raid_directory/ /mnt/
# Unmount it
host# umount /mnt
