Description

For example a file can comprise 5 blcoks . In that we have written 4.5 blocks and invoked sync.
Reading of this 4.5 blocks will be successful at this point of time.
Now when writing the remaining 0.5 block write has failed due to checksum errors, Then the reading of the previously synced 4.5 blocks also fails.
