Read Deleted Data
This command is the same as the Read Data command, only it operates on sectors that contain a Deleted Data Address
Mark at the beginning of a Data Field.
Table 22 describes the effect of the SK bit on the Read Deleted Data command execution and results. Except where
noted in Table 22, the C or R value of the sector address is automatically incremented (see
Table 23).
