ewfverify() LOCAL ewfverify() NAME ewfverify -- verifies media data stored in EWF files SYNOPSIS ewfverify [-A codepage] [-d digest_type] [-f format] [-l log_filename] [-p process_buffer_size] [-hqvVwx] ewf_files DESCRIPTION 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: -A codepage the codepage of header section, options: ascii (default), win- dows-874, windows-932, windows-936, windows-949, windows-950, windows-1250, windows-1251, windows-1252, windows-1253, win- dows-1254, windows-1255, windows-1256, windows-1257 or win- dows-1258 -d digest_type calculate additional digest (hash) types besides md5, options: sha1, sha256 -f format specify the input format, options: raw (default), files (re- stricted to logical volume files) -h shows this help -l log_filename logs verification errors and the digest (hash) to the log file- name -p process_buffer_size the process buffer size (default is the chunk size) -q quiet shows minimal status information -v verbose output to stderr -V print version -w zero sectors on checksum error (mimic EnCase like behavior) -x use the chunk data instead of the buffered read and write func- tions. ENVIRONMENT None FILES None EXAMPLES ewfverify can either verify the raw storage media data or logical file data stored in EWF file(s).

Verbose and debug output are only printed when enabled at compilation.
