Cannot decode file block: Error decompressing block with deflate, possible data error

Hi,

While reading a file using avrocat tool, i am getting errors *Cannot decode
file block: Error decompressing block with deflate, possible data error.*

And when using avro-tools-1.7.6.jar i get Invalid Sync! errors.

Can anyone please tel me why these errors are coming, and is there a way to
correct the file now without loosing any data?

File was created using 1.7.4 C library

Thanks
Amit
