Mismatch with a checksum stored in a negative-azimuth track during C3 error

 

correction while reading. MEDIUM ERROR.

97h

C3 error correction failed during a Read. MEDIUM ERROR.

Mismatch between checksum calculated while reading, and that stored in a positive

 

track. MEDIUM ERROR.

9Dh

Mismatch between checksum calculated while reading, and that stored in a

 

negative track. MEDIUM ERROR.
