How do I extract raw sectors from a CD-ROM?


Hello, I want to extract RAW sectors (2352 bytes) from a CD-ROM to a file in my hard disk. How can I do this? Thanks.

dd---the univerally dangerous power tool

Note: I know nothing about CD formats, but fdisk says that a sector is 2048bytes

Assume that your CD is /dev/hdc:

To read the first 2352 bytes into a file:
dd if=/dev/hdc of=filename bs=2352 count=1

To jump ahead to the 6th block:
dd if=/dev/hdc of=filename bs=2352 skip=5 count=1

to read N blocks: count=1

etc

man dd for more (or find the megathread on dd by Awesomemachine)
