ewfverify is a utility to verify media data stored in EWF files.
ewfverify is part of the libewf package. libewf is a library to access the Expert Witness Compression Format (EWF).
ewf_files the first or the entire set of EWF segment files
The options are as follows:
codepage
the codepage of header section, options: ascii (default), windows-874, windows-932, windows-936, windows-949, windows-950, windows-1250, windows-1251, windows-1252, windows-1253, windows-1254, windows-1255, windows-1256, windows-1257 or windows-1258
digest_type
calculate additional digest (hash) types besides md5, options: sha1, sha256
format
specify the input format, options: raw (default), files (restricted to logical volume files)
shows this help
log_filename
logs verification errors and the digest (hash) to the log filename
process_buffer_size
the process buffer size (default is the chunk size)
quiet shows minimal status information
verbose output to stderr
print version
zero sectors on checksum error (mimic EnCase like behavior)
use the chunk data instead of the buffered read and write functions.
