Yes, this is possible and i do it from time to time. Between Linux kernel
2.6 and 5.6 or 5.7 there was a throughput problem which could be
circumvented by using /dev/sg instead of /dev/sr. See
But meanwhile this has been fixed.

SCSI errors were not a symptom of that flaw. Normally they indicate
individual problems of the hardware.
If you show the particular error messages then i may be able to tell more.

Have a nice day :)
