I was trying to dump Destroyer Command, but I receive errors in the way:

How can I fix these so-called "data errors" and continue dumping?

577 C2 errors looks like SafeDisc, but for some reason it was not detected by Redumper.
Is there a "00000001.TMP" or "00000001.LT1" file in the disc?

Yes, there is a 00000001.TMP file present. Similarly, 00000809.016 and 00000809.256 files are here, but there is no 00000001.LT1 file.

That file and the 577 errors indicates it is SafeDisc.  Usually redumper is able to automatically deal with it.
Please dump using 

--force-split

for this disc. Because it has errors, dump twice to ensure the hashes are the same each time.

Put retries=100 or something. You most likely got an error outside of the Safedisc range

I was able to dump it using --force-split and --retries=100 combined. I don't know if it's 100% correct, but at least I didn't get any error. Sending it to "New disc" forum now.
