I just checked, and all our Toshiba MG07ACA14TE drives run firmware version 0101; and as far as I know, Toshiba doesn't provide firmware images for its drives, so I don't think it's possible to upgrade/downgrade the firmware on those drives. > - Is anyone aware of some HBA or other setting in the middle that > might be masking this setting from reaching the drive? In our case it's an LSI SAS3008 card, and we disable the write cache with `smartctl --set=wcache,off /dev/sdX`.
