This modification enable you to copy from a tape to disk, with information of blocksizes: tcopy /dev/nsa0 . This produces files like: file-000.32768 file-001.32768 file-002.32768 file-003.32768 file-004.32768 file-005.32768 file-006.32768 file-007.32768 In this case is '.32768' the used blocksize on this tape. You can copy each file with dd to a other tape: dd if=file-000.32768 obs=64k conv=osync of=/dev/nsa0 This modification is helpful for recompilation of tapes and changing the blocksizes. >How-To-Repeat: >Fix: --- tcopy.c.orig Thu Nov 7 18:54:42 2002 +++ tcopy.c Tue Oct 7 15:14:07 2003 @@ -32,4 +32,8 @@ */ +/* + Modification 2000 Daniel Mack, Oliver Breuninger +*/ + #ifndef lint static const char copyright[] = @@ -86,5 +90,10 @@ int ch, needeof; char *buff, *inf; + struct stat statbuf; + char Dirname[0xff], FileName[0xff]; + int BlockSize; + bzero (Dirname, sizeof (Dirname)); + bzero (FileName, sizeof (FileName)); msg = stdout; guesslen = 1; @@ -130,7 +139,16 @@ op = COPY; inf = argv[0]; - if ((outp = open(argv[1], op == VERIFY ?
