Linux software to record .iso from optical drive multi session disk

Question

Which Linux software can be used to record .iso from optical drive multi session disk?

I tried k3b but it said it does not support multi session. Tried brasero and it did not detect the optical drive.

Answer 1

You can do it with dd :

1. Reading the block size and the volume size:

[root@testserver ~]# isoinfo -d -i /dev/cdrom | grep -i -E 'block size|volume size'

Logical block size is: 2048

Volume size is: 327867

2. Running dd with the parameters for block size and volume size:

[root@testserver ~]# dd if=/dev/cdrom of=test.iso bs= count=
