You may be out of luck. FreeBSD has a 65536-byte blocksize limit on tape devices. You _might_ be able to read it by running "dd if=/dev/nrsa0 of=tempfile.tar bs=1m", then untarring tempfile.tar, but chances are it won't work. -- Dan Nelson dnelson@allantgroup.com To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
