Hello Richard ... Thanks for your answer
1 / I am using dd 4.1 as follows $ dd --version dd (fileutils) 4.1 Written by Paul Rubin, David MacKenzie, and Stuart Kemp. Copyright (C) 2001 Free Software Foundation, Inc. This is free software; see the source for copying conditions. There is NO warranty; not even for MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. $ 2 / Yes , my system supports SCSI. For example, the command: tar cvf /dev/st1 /etc/passwd /largefile will work fine but I notice that: dd if=/etc/passwd of=/dev/st1 is OK but dd if=/largefile of=/dev/st1 IS NOT OK because the largefile size is biggest than the default blocksize. 3 / I am using 7.1.94 because my system is a IA64 system Thanks for your precious help.
