#This script is used to remake the archive directory tree
# when the USB disk has errors when copied in Boulder.
#This script uses a begin and end YYYYMMDD string to recreate
# the archive directory tree to USB disk.
#The script is called with a DiskToPath, BegYMD and EndYMD, where
# DiskToPath is the path to the USB disk (eg. /media/usbdisk)
# BegYMD is the first day of the archive to recreate
# EndYMD is the last day of the archive to recreate
