I forgot to mention, the program hangs in this code:

   cacheError(fileErrMemError);
   return 2;
  }

  readBytes = FileRead( cache, tempData, 4096, 1, &fileError);
  if (fileError != errNone) {
   cacheError(fileError);
   if (tempData != NULL) Free(tempData);
   tempData = NULL;
   return 2;
  }

  err = VFSFileWrite(fileRefP, readBytes, tempData, &numBytesWrittenP);
  if (err != errNone) {
   VfsError(err);
   if (tempData != NULL) Free(tempData);
   tempData = NULL;
   return 2;
  }

  Free(tempData);
  tempData = NULL;
 }


Thanks,

Do not malloc and free the block inside the loop. Do it outside, break 
in the case of error to free the memory again.
