The program "copytape" makes exact duplicates of SUN 1/4" tapes and
DEC tapes and probably others. This includes boot tapes. Copytape is
available by anonymous ftp from,
ftp.acsu.buffalo.edu ! in pub/copytape.tar
titan.rice.edu
However, "copytape" fails on tapes that contains files whose record
size changes in a file. For example, the following is a partial
listing of the output of tcopy on a SPARCstation of a tape that
"copytape" can not properly copy.
file 6: record 1: size 65536
file 6: record 2: size 9216
file 6: eof after 2 records: 74752 bytes
file 7: records 1 to 174: size 65536
file 7: record 175: size 57344
file 7: eof after 175 records: 11460608 bytes
file 8: records 1 to 42: size 65536
file 8: record 43: size 64512
file 8: records 44 to 50: size 65536
file 8: record 51: size 1536
file 8: eof after 51 records: 3277312 bytes
file 9: records 1 to 7: size 65536
file 9: record 8: size 6144
file 9: eof after 8 records: 464896 bytes
Copytape handles all the files properly except for file 8 which has
record 43 that has a record size different from all the other record
sizes.
Does anyone know of a modified "copytape" that can handle this
situation?

This would be well-received following SMI's recent, *ill-received* (by me, at least) announcement that they will distribute software on CD only. -- Karl A.
