Hi,
Thanks for the feedback. I applied the patch in you previous post but
this makes no difference. I have had a second look at readcd reading the Aopen
CDROM and Plextor CDRW and can confirm your findings re; sector-size and CRC
stuff as follows;
$ readcd dev=0,0,0 -f /dev/null -c2scan # This is the AOpen CDROM
readcd: Warning: controller returns wrong size for CD capabilities page.

Capacity: 274517 Blocks = 630531 kBytes = 615 MBytes = 645 prMB
Sectorsize: 2352 Bytes

Here is the result of an cdrecord verbose inquiry of both drives. Does this
stuff shed any light on what Aopen drive does wrong?

I followed up Jorg's suggestion of firmware updates for the Aopen but there

readcd to read only the true data/2048 sector-size?
