Try using some other --format arguments to tar. The formats are more or less identical for "simple" filesystems, and differ in how they deal with symlinks, long filenames, funny characters, and so on (yes, this is a gross simplification). I suspect that for most of your partitions, tar is creating an archive that doesn't contain anything 7-zip finds confusing, but for this particular partition, tar is creating a tarfile with a GNU-specific option that 7-zip chokes on.
