An error event in the log may be followed by a second error event that can provide additional
information. For example a CDB is issued to VERIFY a data block is shown below.
CDB: 2f 00 13 8e 93 05 00 80 00 00
The CDB indicates that the drive will verify the 0x8000 block written data on the medium using
ECC starting from LBA 0x138E9305.
It is followed by the sense data, which indicates that the drive returned an unrecoverable read
error on the LBA 0x138EF588.
Sense Code: f0 00 03 13 8e f5 88 0a 00 00 00 00 11 00 00 00 00 0
Next the Controller tries to fix the error using the WRITE and VERIFY command, which
indicates that the drive will write 0x01 block data and then verify the written data in the medium
using ECC starting from LAB 0x138EF588.
CDB: 2e 00 13 8e f5 88 00 00 01 00
It is followed by the sense data, which indicates that the drive failed the read command again.
Sense Code: f0 00 03 13 8e f5 88 0a 00 00 00 00 11 00 00 00 00 0
