Read error codes are presented when using tape with Amstrad CPC computers. The possible read error codes are:

  • Read error a: The signal is dropped or timing is incorrect.
  • Read error b: CRC error.
  • Read error c: Invalid file type / seems to be used with "CAS CHECK". This is where you are comparing data in memory with data written to tape. So effectively a verify that data was written correctly.
  • Read error d: Block is too large to fit in the buffer. (given when you do a CAT on large blocks)
