If your drive has a correction offset value of +6 and factory write offset is +2, combined correction offset is +8, 32 bytes (You can, pottentially, miss 8 bytes at the end, not beggining, of disc). Thus, if you use audio trap disc, you can extract 0 - 50197 range using CDTool (With C2 reporting enabled, subchannel reading (Raw mode and deinterleaving enabled) and Main+Sub+C2 read order). You have to substract 32 bytes at the beginning of dump and append 32 zeroed bytes in the end. Start of a data track scrambled is always 00 FF FF FF FF FF FF FF FF FF FF 00 01 82 00. (00 FF FF FF FF FF FF FF FF FF FF 00 02 00 00 once descrambled).
Then, open SubCode Analyzer, load .sub and make CUE file. This CUE file is useful for spliting dump with CDMage and, then, descramble data track. If everything is fine (Tracks properly cutted, no missing data...), you will get a match. With trap disc method and my Pioneer drive I have dumped several discs for my personal archive and they match database.
Every utility noted is here:
PS: As far I know, also IsoBuster extracts ranges in burst mode, not single sector mode.
