LBA and UDF errors

[Megalith]

Can someone explain to me what these are, and if they are a real concern?

 

Once in a while, I will get a "possible UDF error" after verifying a DVD burn, and a "Miscompare at LBA" error after verifying a CD-R burn (which happens much more frequently).

[LIGHTNING UK!]

UDF error is where the program didn't build the filesystem properly.

 

Miscompare is where the data on the disc doesn't match that of the image. So either the disc messed up or something else is manipulating the data 'on - the - fly' so to speak.

 

Yes, both a bad.
