Aaru.Documentation/Creating-a-dump-from-physical-media.mediawiki

==Command description==
This operating will create a dump image from real media using a physical device. It will retry errors and when finished create an XML metadata sidecar and an Alcohol 120% media descriptor for optical media. The dumping operation can be interrupted and continued later, even with a different device.

==Command usage==
<code>DiscImageChef dump-media -i <device> -v [true/false] -d [true/false] -w [prefix] -r [true/false] -s [true/false]
 -f [true/false] -p [passes] --persistent [true/false] --separate-subchannel [true/false] -m [true/false] --lead-in [true/false]</code>

<code>-i, --input=<dump></code> path to the physical device<br />
<code>-v, --verbose=[true/false]</code> shows verbose output ''(default false)''<br />
<code>-d, --debug=[true/false]</code> shows debug output ''(default false)''<br />
<code>-w, --output-prefix=[prefix]</code> prefix of the name for the dump media files<br />
<code>-r, --raw=[true/false]</code> dumps sectors with all of their tags, or for optical media, dumps scrambled sectors ''(default false)''<br />
<code>-s, --stop-on-error=[true/false]</code> stops dumping on first error ''(default false)''<br />
<code>-f, --force=[true/false]</code> continuing dumping whatever happens ''(default false)''<br />
<code>-p, --retry-passes=[true/false]</code> how many times to retry reading a sector ''(default false)''<br />
<code>--persistent=[true/false]</code> try to recover partial or incorrect data ''(default false)''<br />
<code>--separate-subchannel=[true/false]</code> save subchannel in a separate file. Only applicable to CD, DDCD or GD media ''(default false)''<br />
<code>-m, --resume=[true/false]</code> create and/or use resume mapfile ''(default true)''<br />
<code>--lead-in=[true/false]</code> try to dump Lead-in. Only applicable to CD, DDCD or GD media ''(default false)''<br />

==Example==
FreeBSD: <code>DiscImageChef dump-media -i /dev/cd0 -f --persistent=true --separate-subchannel -w mydisc</code><br />
Linux: <code>DiscImageChef dump-media -i /dev/sdb -r -f -p 15 -w myusbfloppy</code><br />
Windows: <code>DiscImageChef dump-media -i \\.\PhysicalDrive3 -f -p 0 --resume=false mydisk</code><br />
