I have an audio disc that I want to produce a one to one ISO of (it has some marks).
When I try to use “ddrescue” to copy it, I get the following error message.
ddrescue: /dev/sr0: Unaligned read error. Is sector size correct?.
What am I doing wrong? I would assume “ddrescue” would automatically figure out the sector size.
To note, I want to use “ddrescue” because “abcde” keeps hitting read errors on the disk.
Edit:
Seems that “ddrescue” does not support audio discs (https://unix.stackexchange.com/a/558628).
And “abcde” already uses “cdda paranoia”.
Because audio CDs get written the opposite way to data CDs. I forget which is which but one gets written outside-in and the other inside-out.
That’s not right; both audio and data discs are burned and read inside to outside, which is the opposite of vinyl records.
Passing “–reverse” to “ddrescue” does not help, leading to the same error message. 🙁
