The same thing applies to reading after the last filemark. Note that after writing a filemark at the beginning of the tape, the situation is different. Now there is a file and the normal EOF semantics apply although there still is no data. I admit that the error return could be more descriptive but the st driver tries to be compatible with other Unices. The behavior can be changed if Linux does not match other Unices. I don't remember if I have tested just this with other Unices. I will try to test this with Tru64 tomorrow. If anyone has data on other Unices, it would be helpful. -- Kai - To unsubscribe from this list: send the line "unsubscribe linux-ide" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
