I don't think it is possible. The label is part of the first tape file and tapes don't support rewriting in the middle or at the start (only appending). > How can I make a dump of the tape to disk, so that I have more than one > try on this? I tried dd, but this needs a block device as source. What error did it give? dd if=/dev/nst0 of=/tmp/file should work. Note however, that you probably won't be able to read anything useful from this tape, only the zero length file at that was written over the label. __Martin ------------------------------------------------------------------------- This SF.net email is sponsored by: Splunk Inc.
