Finding out what is the USB drive in /dev/sd*

Start by mounting the stick which should be automatic in GUI.

mount|grep /dev/sd

should tell what is the /dev/USBSTICK

Creating bootable USB stick

isohybrid image.iso
dd if=image of=/dev/USBSTICK bs=1024;

Creating .iso from CD/DVD

First unmount the CD/DVD and then

dd if=/dev/DRIVE of=image.iso

DRIVE can be /dev/dvd /dev/cdrom or /dev/scd0 depending on the CD/DVD.

Backing up scratched CD/DVD

ddrescue -v /dev/device /where/to/create/the/file.iso /path/to/logfile.log

The logfile.log is used to keep track of what has been recovered. You can use same logfile for multiple clones.

Usage: You have two broken copies of same device. First you clone the other and then give same command to other, different source, but same destination and log file. If the device isn’t broken on same part as the another, ddrescue will build a complete file.

I would also use ddrescue with backing up large devicces instead of dd.
