Since it can't be both at the same time. Right ?
So which one is really used ?
Alcohol User Manual wrote:Write Method: Includes DAO/SAO (default), RAW SAO, RAW SAO+ SUB, and RAW DAO. Most CD/DVD recorders support DAO/SAO writing mode, but not every CD/DVD recorder supports RAW writing mode. You can check which writing modes your CD/DVD recorder supports in “System Info” in the above window.
DAO/SAO writing mode is used to backup normal CD/DVD discs. In contrast, RAW writing mode is used to backup raw data of CD/DVD discs (mainly for special CD/DVD formats).
As far i understand over Alcohol 120% :
(The Disc At Once method always allow the writing of RAW 2353 byte sectors with some subcode channels variations) :
1) RAW (DAO) : where the 96 bytes of associated P-W subcode channels are ALWAYS generated by the HARDWARE recorder.
2) RAW DAO-16 : where the 16 bytes of associated P-Q subcode channels are generated by SOFTWARE (but R-S-T-U-V-W by HARDWARE).
3)*RAW DAO-96 : where the 96 bytes of associated P-W subcode channels are ALWAYS generated by SOFTWARE.
*N.B : Best CD-R DAO write mode is #3 since :
(It allows writing of all subchannel information, including Digital Signatures, CD-Text, ISRC, Catalog Numbers, CD+G, CD+Midi, Gaps, Indices, TOC, etc.)
I beleive the setting in Alcohol "Write Method" = DAO/SAO is using DAO write mode #1.
But i dont understand what's SAO has to do into this..
DAO always write in RAW but have some subchannel variations.
(SAO is another story.)
Someone could tell me which write method between DAO or SAO is actually used when burning a CD in "Normal CD" datatype.
My burner have some big problems reading back DAO RAW-96.
But, my burner could read back the CD'R if it was previously burned over DAO/SAO
I would like to confirm it could read back DAO (RAW). (And not SAO)
