I've tried that command in terminal mutiple times and it hasn't worked. Are there any alternative commands? I've also tried sudo trimforce disable

Hi Trina,

This will disable trim on the pegasus2. You must have the Promise Utility installed to access the CLI.

 

MacBook-Pro:~ promise$ promiseutil

-------------------------------------------------------------

Promise Utility

Version: 4.02.0000.12 Build Date: Apr 20, 2018

-------------------------------------------------------------

List available RAID HBAs and Subsystems

===============================================================================

Type  #    Model         Alias                         WWN                 Seq

The row with '*' sign refers the current working HBA/Subsystem path

To change the current HBA/Subsystem path, you may use the following command:

  spath -a chgpath -t hba|subsys -p <path #>.
