raw2iso MODE1_RAW RW does not produce a valid ISO image

[xeyownt]

The following works:

cdrdao read-cd --read-raw --read-subchan rw_raw --device /dev/cdrom data.toc
raw2iso MODE1_RAW RW_RAW < data.bin > data.iso

The following doesn't:

cdrdao read-cd --read-raw --read-subchan rw --device /dev/cdrom data.toc
raw2iso MODE1_RAW RW < data.bin > data.iso

In that latter case, the iso image is not valid (eg. error using isoinfo or mount).

Thanks for filing! I'll investigate when I find the time. According to the code, raw2iso treats RW and RW_RAW equivalently.

... and thanks for this small piece of code. It was extremely useful to me for archiving old DVD's I had (trying to go full digital), and making sure the ripping was correct, etc.

Cannot reproduce here. Using an old, pressed game CD-ROM and the stock Fedora cdrdao 1.2.4, both methods yield identical results:

[not-a-user@not-a-box scratch]$ raw2iso
Convert raw optical disk images to iso files.

Usage: raw2iso <track-mode> [<sub-channel-mode>] < INPUT.BIN > OUTPUT.ISO

<track-mode>: MODE1_RAW | MODE1 | MODE2_RAW | MODE2_FORM1 | MODE2_FORM2 | MODE2_FORM_MIX
<sub-channel-mode>: RW | RW_RAW

(See cdrdao(1) -> TOC FILES -> Track Specification -> TRACK.)

Note: Error correction/detection data is not checked (try
https://github.com/claunia/edccchk) and errors are not corrected.

Which software, hardware and media are you using?

@xeyownt And I thought DVDs already where all digital.
