* Handling I/O errors and end of tape conditions are a bit tricky.

- * to include ST_EOT, which is ephimeral, and ST_WEOT, which is
+ * to include ST_EOT, which is ephemeral, and ST_WEOT, which is
* persistent. Lots of routines clear ST_EOT, but ST_WEOT is
* cleared only when the problem goes away. Now when ST_WEOT
* is set all calls to write_block_to_device() call the fix_up
