3.2.2Set Features command (EFH)

The Set Features command (command code EFH) allows you to enable and disable the multisegmented cache and Automatic Reallocation features and to identify the transfer modes the drives use. The multiseg- mented buffer consists of Read Look-ahead and write-immediate and write-merging features. The table below lists the features the drives support. The features that are set to default by the factory are indicated in the Feature column.

To use the command:

1.Write the Feature value to the Features register.

2.Write the Set Features command to the command register.

Note. If the value in the Features register is not supported or is invalid, the drives post an Aborted Command error.

At power-on or after a hard reset, the feature selections are restored to the factory-default values.

The table below shows alterable features that the drives support. Values that are preset at the factory are indicated as default in the feature description.
