ATA-66, most likely. The cable length has been cut to 18" max.

You can't copy vcd sectors directly, you have to use the CDROMREAD*
ioctl to get to the data. There are several video-cd players out
there that do that, so you just need to get one of them.

There you are, the command used to read the sector is not right for
video cd.
