Recently I bought a LG 8164 in order to dump some NGC PAL games.
I am using friidump because rawdump does not recognise the drive.
I first dumped a game already in the db and it matched.
Then i dumped another 3 "new" games twice and 1st and 2nd dump matched.
But when i dumped another "new" game twice 1st and 2nd did NOT match.
Compared the 2 dumps > 1 byte is different.
So my question: What to do?

I'd say the drive is either damaged, or has some bad firmware if rawdump doesn't recognize it. My 8164 works perfectly with rawdump.

it's strange, friidump does EDC check, it shouldn't pass with errors.
if it's molested version maybe i messed up something.
you could try last official.
or dump in raw instead and then feed this to decoder.
if different raw images pass through decoder, something is wrong with friidump.
otherwise it could be HDD bit flip maybe.

I used friidump 0.4 but I will try 0.5.3 now.

I don't know how to dump in raw instead and then feed this to decoder.

And HDD bit flip is also abracadabra to me.

Edit:

Dumped this game 3 times with 0.4 and one time with 0.5.3:
dumps 1, 3 and 4 match and dump 2 is 1 byte different.

Can i report this dump based on dumps 1, 3 and 4?

yeah, it's fine
i've checked friidump and it's pretty impossible for it to pass bad sectors
EDC check is part of core decoding logic
it's likely to be HDD fault then
could it be IDE and on the same cable as CD unit?
to be certain in future you could make raw image with -r switch instead of -i
and afterwards decode this image twice, with -u parameter:
friidump.exe -u "input.raw" -i "output.iso"

Very likely, got my first bad sector the day before.

No.

oh, better don't stress it then
could be it's getting ready to pass on
maybe disconnect completely until you can make backup
it always sucks when HDD dies
good luck!
