Generally, it's better to have success at the end
of a function and either a goto error or return
error for error conditions.
Something like:
if (!(!memcmp(redundant+0x0D, EccBuf, 3) &&
!memcmp(redundant+0x08, EccBuf+0x03, 3)))
return ERROR;
return SUCCESS;

You might as well take out useless code after returns
instead of just changing function names.
If you keep it you should reformat it.
if (memcmp(redundant+0x0D, EccBuf, 3) &&
_Correct_D_SwECC(buf, redundant+0x0D, EccBuf))
return ERROR;
etc...
