Dcfldd is a modified version of GNU dd.
The major features added are:
- Hashing on-the-fly: dcfldd can hash the input data as it is
being transferred, helping to ensure data integrity.
- Status output: dcfldd can update the user of its progress in
terms of the amount of data transferred and how much longer
operation will take.
- Flexible disk wipes: dcfldd can be used to wipe disks quickly
and with a known pattern if desired.
- Image/wipe verify: dcfldd can verify that a target drive is a
bit-for-bit match of the specified input file or pattern.
- Multiple outputs: dcfldd can output to multiple files or disks
at the same time.
- Split output: dcfldd can split output to multiple files with
more configurability than the split command.
- Piped output and logs: dcfldd can send all its log data and
output to commands as well as files natively.
