Dumping Dreamcast GDRs with bad sectors?

Hey all, quick question.

I'm in the middle of dumping a bunch of old GD-Rs with dcsdrip and came across a few stubborn discs that seem to have some bad sectors but otherwise play fine. I kept redumping the same few discs again to see if it was just a fluke but I keep running into the same problems with them. I was wondering if anyone had any experience with dumping games with bad sectors with something like DreamShell, or if there might be some other alternative method that involves maybe BBA/Sd cards that can get over the bad sectors? dcsdrip doesn't seem to have the ability to skip the bad sectors on the disc but DreamShell seems like it can. Although I haven't heard many stories for dumping with DreamShell since everyone just goes with dcsdrip.

If anyone has any recommendations, please let me know. Thanks!

 

I know one method of ripping GDs using BBA and httpd-ack. I'm not sure if GD-Rs are different


I'm not sure if there is options for skipping bad sectors though

 

httpd-ack can handle bad sectors but requires modifying the url used to download the track. You will want to make 2 changes to the url

sector_read16 to sector_read1
abort1 to abort0

This will cause httpd-ack to read 1 sector at a time (will make dumping a little slow) and to not abort on read error. sectors that cant be read will be fill with the letter Q for their data to make it easy to find them with a hex editor.
