Hi Sarami,

I recently had a couple of discs that produced huge subError.txt (>900MB) files. The dumps were fine but the huge subError files made MPF go haywire. At first I thought it was because the discs got scratches but this one I'm dumping right now is really mint. Could you check the logs?

The game is a rerelease of Panzer General.

This subRtoW is rare. Not to detect as suberror.

I have a disc (Rayman CP Calcul) that is consistently giving a couple of bad sectors (same each time) when dumped with a Plextor (755), but the dump appears fine when dumped with an ASUS BW-16D1HT.

The sectors appear to have no sync when dumped with the Plextor.

Plextor sometimes shifts some bytes when dumps the disc.

So which dump is correct? Is this a plextor bug or are these bytes actually shifted on the disc. If it is a plextor bug, can it be resolved?

Asus.

I think so.

It's impossible for me. If this is firmware problem, it might be valid to downgrade it.

Is there an error with DIC or is it normal to see 0 errors although SecuROM 5 is used on this disc?

Multiple dumps produce the same result.

There was a message regarding sectors which lack ECC though, so I guess it would be normal to see no errors for those sectors because they couldn't be checked.

The 4th sector from the last does not change the mode.
