I recently went through a big effort of swapping my linux install over to my SSD, to gain speed and power savings.
However I can still hear the hard drive spinning sometimes, particularly for the first 30 or so seconds after coming out of sleep/boot etc.
The drive isn't mentioned in fstab, all there is on the drive is a windows partition and an ext4 position (brand new, untouched)
Is there a way to make linux ignore the disk, so it never spins up? Bonus points: Can it be done while still mounting a data partition, such that it spins up before doing any data read/writes?
Edit: Running linux mint 18.1 kernel 4.4.0-83, on an asus harman/kardon with a 120gb ssd and 1TB HDD.
