It may be a problem with the CD itself. Another possibility is the use
by the interface of a faster timing than the CD-ROM is capable of.
Most or all modern CD-ROMs can handle PIO mode 3 as this is mandatory in
the latest ATAPI revision. Mode 3 should be enough in your case, but I
don't know the specs for your CD-ROM.
If you have the possibility of slowing down the interface, try that.
Connecting the CD-ROM to the secondary cable would be a good idea as

ATAPI devices are designed to be compatible with ordinary IDE (ATA)
controllers. There are no EIDE CD-ROMs in the sense that they need
an EIDE controller to work properly.

It does nothing for the CD.
