CRC issues

[2efPer]

if (crc.calcCRC(block) != readCRC(crc)) { throw new InvalidBlockException(); }

I think it's something wrong about the algorithm , it always throw the InvalidBlockException.
Could anybody fix it?

Hi,

Please, send to me content of block on wich you receive an error. I will check checksum

Use byte type definition the block,only represent 127 blocks，is there some mistakes? I can only transfer 127k

protected void sendDataBlocks(DataInputStream dataStream, byte blockNumber, CRC crc, byte[] block) throws IOException {
int dataLength;
while ((dataLength = dataStream.read(block)) != -1) {
sendBlock(blockNumber++, block, dataLength, crc);
}
}

Use byte type instead of int type ,then solve the problem
