Created page with "# copy CD/DVD to iso image and mount Copy ``` dd if=/dev/sr0 of=my-output.iso bs=10M ``` Mount ``` sudo mount -t iso9660 -o loop lotrbfme2-2.iso /tmp/a ``` Using noerror fo..."

New page

# copy CD/DVD to iso image and mount

Copy
```
dd if=/dev/sr0 of=my-output.iso bs=10M
```

Mount
```
sudo mount -t iso9660 -o loop lotrbfme2-2.iso /tmp/a
```

Using noerror for attempt at protected disk

You may get something like this
```
dd: error reading '/dev/sr0': Input/output error
51+1 records in
51+1 records out

```

This may work but
```
dd if=/dev/sr0 of=my-output.iso bs=10M conv=noerror,sync status=progress
```

Try these two commands

Get volume size
```
isoinfo -d -i /dev/sr0 | grep -i -E 'block size|volume size'
Logical block size is: 2048
Volume size is: 2264834
```

Set count to volume size value
```
dd if=/dev/sr0 of=my-output.iso bs=2048 count=2264834
```
