http://redump.org/disc/54329/ -- why was it altered? Do you understand the fixable error there isn't a read error? How many other fixed submissions do we have?

I don't think that error should be there, but we will see when TeamEurope redumped the disc. I don't remember any similar cases.
If any of the dumpers remember a dump with no c2 errors that was changed some way after submitting - please, write here.

Or ask iR0b0t to make a report that shows any dumps with modified clrmame data compared to the original submission?

http://redump.org/disc/54329/ can't be redumped because the disc was returned to the guy who sent them.
Similar issue from same dumper/same drive: http://forum.redump.org/post/63120/#p63120
Hopefully sarami can find out the cause of this issue. In any case I think the 0 error dumps are more trustworthy.
I still think it could be some kind of mastering error and in any case dumps without c2 errors shouldn't be blindly fixed.

I don't think we have any similar cases were a normal drive/dump produces a valid data sector, but a d8 plextor dump gives invalid sectors that are preferred instead? I wonder if it's even possible to master a mode1 sector where ECC/EDC doesnt match and it also isnt any protection or end-of-datatrack mastering error. If we found such cases before, the dumps were deemed suspicious and needed to be redumped: http://forum.redump.org/topic/16655/ibm … to-redump/ so I'm still convinced that it's some kind of firmware/drive bug.

Can you check what's wrong?

Perhaps drive's cache is broken (or firmware/drive/dic bugs?). It maybe is fixed if rereading (but it's not supported yet in this case).
Same dumper, same drive, same problems. Non-plextor dump is good. Why do you keep mistrusting me?

If I remember rightly, some Sega Saturn discs (perhaps +588/+1176 offsets?) have duplicate sector in the pregap of track 1.
Or some FM Towns discs are same. http://forum.redump.org/topic/16418/add … new-dumps/
These pattern can't recognize at 0xbe (non-plextor drive) ripping. Is TeamEurope disc similar pattern? I don't know now... It needs to dump by other drive and other disc.
As a result, you maybe are right. But you shouldn't have fixed it without consultation and discussion, should you?
At least, I think you shouldn't add the disc which is suspicious of the error in the db directly, for reliable db.

The discs are mine and i have already dumped them before on another forum anyway.
If one of my cd's needs to be redumped it will be redumped as soon as possible.

I was going to wait for the redump of TeamEurope's own Amiga Plus CD ROM No. 2/98 disc with a similar issue before bothering you
