Whilst I don’t know what protection this game uses, if you encountered 400 read errors early in the reading process, it’s almost certainly safedisc 2.
If so, you quit too early. Safedisc 2 protected cds generally have 550 to 600 bad sectors which are all contained in the first 10,000 sectors (out of approximately 300,000 or so). After blindread has finished reading the bad sector area normal extraction will resume and it will only take another 2 or 3 minutes to read the rest of the disc. Just be a little more patient.
Assuming that it is safedisc 2 protected, you won’t have any problems making a working back-up with your writer. If using blindwrite burn the image using dao pq or dao pw and do not check enhance weak sectors. If using clonecd, you can just use the default gamecd profile but make sure that you have disabled AWS from the settings sheet for your writer.
Note also that if you want to play the back-up copy from your writer rather than an ordinary cd/dvd rom, you will have to enable clonecd’s hide cd media before doing so.
