我試咗新 d 嘅 HDD support PUIS, i.e. "sdh - HGST NAS".
"sdc - WD Green" 就唔 support.
但因 BIOS/Controller/OS 未能 support, 起機隻碟會 missing 咗, 所以用唔著.

root:~# hdparm -s0 --yes-i-know-what-i-am-doing /dev/sdh

/dev/sdh:
spin-up: setting power-up in standby to 0 (off)




root:~# hdparm -s0 --yes-i-know-what-i-am-doing /dev/sdc

/dev/sdc:
spin-up: setting power-up in standby to 0 (off)
HDIO_DRIVE_CMD(powerup_in_standby) failed: Input/output error

16-20 bay應該用HDD Enclosure, 再由enclosure供電
