Try the command lines from the example section in the man page ;-) |

This is a useless command line as -C /media/sda1 is executed after archiving |
25 |
/media/hda5. |

There seems to be a problem with xattr support on your system. |
41 |
Unfortunately, Linux allows you not to install a sufficiently complete OS |
42 |
basesystem. |
43 |
|
44 |
Make sure that not only star supports xattrs. |

As I don't know what's in both files, I cannot comment. |

If you create a tar archive with POSIX.1-2001 extensions, you get at least |
67 |
1kB of additional meta-data per archived file. |
68 |
|
69 |
GNU tar does not support Linux specific extensions... |
