oops. -x = extract.

ok. that does make for better understanding.

i stopped using tar years ago in favor of cpio, which has more advantages,
when i was using tape for archiving. works well with usb memory and usb
hdd drives. in fact, when i archive paths between hdd partitions or drives,
i use cpio instead of "cp -R".

to perform same using cpio, command line would be;

  find path2BigDirArchive -depth -print0 | sort | cpio -p -adm  /sdc1
or
  find . -depth -print0 | sort | cpio -p -adm  /sdc1

in above, "-p" is 'copy-pass mode', equivalent to "|" and "-x" in tar.

because you are having response time issues with usb, i believe you will
find cpio to be more favorable than using tar.
