The speed advantage appears only if the loaded session was produced with
-disk_dev_ino "on" too.
.TP
\fB\-md5\fR "on"|"off"
Enable or disable processing of MD5 checksums for the overall session and for
each single data file. If enabled then MD5 checksums get loaded from the image
if there are any. At image generation time they are computed for each file
which gets its data written into the new session. The checksums of files which
have their data in older sessions get copied into the new session.
For now checksums can be exploited only via find action get_md5.

\fB\-rom_toc_scan\fR "on"|"off"[:"emul_on"|"emul_off"]
Read-only drives do not tell the actual media type but show any media as
ROM (e.g. as DVD-ROM). The session history of MMC multi-session media might
