DAT tapes can use a variety of densities and block sizes, and can use compression. You typically have to use "mt" to set the drive to use the same settings as were used for writing the tape. A corollary of this is that the drive used for reading the tape has to support the format with which it was written. -- Glynn Clements <glynn@xxxxxxxxxxxxxxxxxx> - To unsubscribe from this list: send the line "unsubscribe linux-admin" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
