12.3.2 Mode Sense data
The Mode Sense command provides a way for the drive to repo
rt its operating parameters to the initiator. The
drive maintains four sets of mode parameters:
1. Default values
Default values are hard-coded in the drive firmware stor
ed in flash E-PROM (nonvolatile memory) on the
drive’s PCB. These default values can be changed only by downloading a complete set of new firmware
into the flash E-PROM. An initiator can request and receive from the drive a list of default values and use
those in a Mode Select command to set up new current and saved values, where the values are change-
able.
2. Saved values
