You are correct. Actually my problem is that tar, cp, dd, and cat all
return the same result. My test app was specifically designed for this
list. I fixed my test app. It returns the same result.
#include <stdio.h>
#include <fcntl.h>
main()
{
if (open("/cdrom/dbed_ora.3.5.sol.CD.tar.Z",O_RDONLY) < 0) {
perror("open error");
}
When I get home tonight I will try this out on my systems there. I doubt
that the SCSI cd driver will produce any different results than the acd
driver on my system here at work does.
I've tried other CDs, all to no avail (I thought it was the Oracle CD I was
using at first but RedHat CDs exhibit the same behaviour).
