dc3dd 7.2.640 DCCI 2012-10-09 Issues: ------- When imaging to a device with verification under Mac OS X, verification can fail due to automatic mounting of the target device. One solution is to use Disk Arbitrator in conjunction with dc3dd on OS X. New Features: ------------- Log output may be sent to multiple job logs and hash logs. Simply specify log=LOG and/or hlog=LOG more than once. Verification of an image restored to a device larger than the image is now supported. Specify hof=DEVICE to hash only the bytes dc3dd writes to the device. Specify fhod=DEVICE to hash both the bytes dc3dd writes to the device and all the bytes that follow, up to the end of the device. Specifying hof=DEVICE will now default to phod=DEVICE behavior (hash only the bytes output by dc3dd, not the full device). Building dc3dd: --------------- dc3dd is distributed as source code and must be compiled before use. The default configuration can be built and installed to /usr/local/bin with the following commands: $ tar zxvf dc3dd-7.2.640.tar.gz $ cd dc3dd-7.2.640 $ ./configure $ make $ sudo make install Note that autoconf-1.10.1 and gperf may need to be installed prior to execution of the above commands. dc3dd can be customized at compile-time with various options. The available options are as follows, and can be verified after compilation using the --flags command line option: -DDEFAULT_HASH_MD5 (equivalent to hash=md5 command-line option) -DDEFAULT_HASH_SHA1 (equivalent to hash=sha1 command-line option) -DDEFAULT_HASH_SHA256 (equivalent to hash=sha256 command-line option) -DDEFAULT_HASH_SHA512 (equivalent to hash=sha512 command-line option) -DDEFAULT_OUTPUT_FILE_SIZE=BYTES (equivalent to ofsz=BYTES command-line option) -DDEFAULT_VERBOSE_REPORTING (equivalent to verb=on command-line option) -DDEFAULT_COMPACT_REPORTING (equivalent to nwspc=on command-line option) -DDEFAULT_DECIMAL_BYTES_REPORTING (equivalent to dbr=on command-line option) --enable-hpadco Enable checking ATA/SATA drives for hidden areas No command-line equivalent, cannot be overridden. These options are enabled by including them in the CFLAGS argument to configure. For example, to enable MD5 hashing and default output file size: $ ./configure CFLAGS="-O2 -DDEFAULT_HASH_MD5 -DDEFAULT_OUTPUT_FILE_SIZE=1900M" The program can be statically linked by adding "-static" to the CFLAGS compile options: $ ./configure CFLAGS="-O2 -static" Portability Notes: ------------------ Mac OS X: To enable error recovery, use /dev/rdisk* instead of /dev/disk* Windows: dc3dd can be compiled using Cygwin, but bad sectors can put the program into an infinite loop due to bugs in Cygwin.
