/dev/cmt00 (internal CMT), /dev/sysdat (internal DAT)
The length of a fixed-length blocked tape is an integer multiple of 512-byte blocks. Because management information is not recorded on the medium, only 512-byte integer multiples of data can be handled. Therefore, this medium cannot handle binary format.
Files in DAT format are handled by padding the unused portion of the last block with 0x00 (0x00 is not normally found in DAT-format files).
Copy DAT-format file '/etc/csh.login' to CMT internal tape '/dev/cmt00':
dd if=/etc/csh.login of=/dev/cmt00 conv=sync![]() ![]() |
