Do I have to use / raw to rip the DVD correctly?

RAW DVD dumping is theoretically useful to preserve the discs with CSS protection, but it stresses the drive heavily and I'm not aware of any programs that could convert the 2064 RAW images into 2048 + CSS keys.

Do you use /raw only for DVD-Video?
By the way, is it for the DVD where /c is also used CSS?

I think both "/raw" and "/c" are for experiments.

So, when ripping a DVD, is there no problem if /raw and /c are not considered?

If you want to get as much data as possible - "/raw" and "/c" are needed. If you only want to dump for redump.org - not needed.

Is the DVD option basically unnecessary.
Thank you admin.
I am very sorry. I have three more question.
but is it safe to specify ALPHA-ROM and Safe-disc DVD without any options?
Is the submission without Barcode invalid?
Is it unnecessary to use /a and /f?

For SafeDisc DVDs there was a test version of DIC with the "/sf" switch enabled for DVDs, try to ask sarami for details.
Alpha-ROM is listed as unsupported in readme.md:
## Unsupported Disc
...
Protected Disc
- SecuROM(v4.x or higher), StarForce, CD-Cops [recording density]
=> These needs DPM(Data position measurement). cue, ccd doesn't support DPM.
You need to use the [Alcohol 120/52%](
http://www.alcohol-soft.com/) to store it,
- Alpha-ROM, ROOT, TAGES [duplicated(double, triple) sector]
=> It can read in reverse, but specifications are not decided in redump.org

You mean the box or spinecard/obi barcode? No, they are optional.

/f is recommended for the protected and scratched discs (safer cache erasing), but not necessary. Also recommended for dumping very small discs (smaller than 8 MB for PX-716A, smaller than 2MB for other Plextors).
/a is usually not needed (sometimes needed when the Audio CD verification doesn't match the redump.org entry).

Answer thank you admin.
Safe-DiscDVD is officially not implemented, OK
The specification of ALPHA-ROMDVD is not decided = not supported, OK.
Isn't the /a and barcode mandatory for discs submitted for the first time?

Code: Select all
Option (for CD read mode)
/a Add CD offset manually (Only Audio CD)
val samples value
This "/a"? Nope, usually not needed (as described in my previous post). Barcodes aren't mandatory, only the ringcodes are really important.
