That is because bzip2, by default, uses a much larger block size than gzip.
Gzip's default block size is a mere 32k, whereas bzip2 uses a default 900K
block. That's one of the reasons bzip2 can deliver such better compression.
Even so, it's wrong to say that bzip2 silently ignores errors in compressed
files. If a CRC check fails, you get this message:
bzip2: Data integrity error when decompressing.
Input file = foo, output file = bar
It is possible that the compressed file(s) have become corrupted.
You can use the -tvv option to test integrity of such files.
You can use the `bzip2recover' program to attempt to recover
data from undamaged sections of corrupted files.
If you find a case where bzip2 silently fails to report an archive error, tell
us how to reproduce it. Maybe the problem can be fixed.
