NAME

ewfverify — verifies media data stored in EWF files

SYNOPSIS

ewfverify [-A codepage] [-d digest_type] [-l log_filename] [-p process_buffer_size] [-hqvVw] 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 support the Expert Witness Compression Format (EWF). libewf supports both the SMART format (EWF-S01) and the EnCase format (EWF-E01). libewf currently does not support the Logical Volume format (EWF-L01). EWF-X is an expirimental format intended for testing purposes to enhance the EWF format. libewf allows you to read and write media data in the EWF format.
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), windows-874, windows-1250, windows-1251, windows-1252, windows-1253, windows-1254, windows-1255, windows-1256, windows-1257, windows-1258
-d digest_type
calculate additional digest (hash) types besides md5, options: sha1
-h
shows this help
-l log_filename
logs verification errors and the digest (hash) to the log filename
-p process_buffer_size
the process buffer size (default is the chunk size)
-q
quiet shows no status information
-v
verbose output to stderr
-V
print version
-w
wipe sectors on CRC error (mimic EnCase like behavior)

DIAGNOSTICS

Errors, verbose and debug output are printed to stderr when verbose output -v is enabled. Verbose and debug output are only printed when enabled at compilation.
