Reposted-by: emv@msen.com (Edward Vielmetti, MSEN) 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 contain 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? Rob Richards Stanford University
