Berkat hdparm -B1 /dev/sdb
HDD saya tidak lagi berputar ketika dinyalakan saat boot. Tetapi setelah menyelesaikan pesan BIOS POST dan memulai Ubuntu, HDD mendapatkan sinyal melalui kabel data SATA dan berputar.
Membiarkan kabel data (tetapi masih dengan kabel power SATA) membiarkan sistem melakukan booting sepenuhnya dari SSD saya tanpa memutar HDD.
Apa yang menyebabkan HDD berputar? Mungkin Grub2?
Sunting: tidak, sepertinya bukan Grub2 yang memutar drive. Saya baru mengatur Grub untuk menampilkan menu tanpa timer. Nothings terjadi sampai saya menekan opsi boot standar Ubuntu, kemudian beberapa detik kemudian drive berputar.
