Figure 92. Mode Page 7 (Verify Error Recovery Parameters)

The Verify recovery parameters are used for VERIFY command and verify potion of WRITE AND VERIFY
command.
PER, DTE, and DCR settings in page 7 override those of page 1 during VERIFY and verify portion of
WRITE AND VERIFY commands.
! PER. See below for description of bit values.
! DTE must be zero since the drive always continues on recovered verify operation errors.
! DCR. See below for description of bit values.
There are only four valid conditions for the PER, DTE, and DCR bits. All other combinations return
CHECK CONDITION status.
PER DTE DCR
0 0 0
1 0 0
0 0 1
1 0 1
! Verify Retry Count sets a limit on the amount of ERP steps the drive attempts when recovering
errors during processing of VERIFY or WRITE AND VERIFY command. A value of 0 disables all
recovery. A values of 1 enables all steps of ERP. Only the values of 0 and 1 are valid.
! Verify Correction Span is ignored.
