Hard Drive - If the power is cut, can that be bad for it?
I use SynBackPro to make two "mirror" copies of one folder on my C: to two 1 TB hard drives: Western Digital Black WD1003FZEX
WD Black
I have the hard drives on a power strip. I power them on and off, about once per day, to make a daily backup.
After the copy has been completed, I use "USB Disk Ejector" to "safely remove" the hard drives

Sometimes, it takes 30 to 60 seconds for a drive to "eject". Sometimes, they both "eject" immediately.
After being "ejected" / disconnected, the drives continue to spin . . .
1.) If I wait for 20 seconds, they auto-power off / auto-power down.
2.) What I have been doing, however, is just cutting the power to them, when they're still spinning.
My question is - with #2 - I haven't noticed anything, but could this have a negative effect on the hard drives, or the data?
I'm thinking that with #1, the needles must "park" themselves, which is what you want - but this cannot occur in scenario #2.
But, I don't know how hard drives work that well - for all I know, the needles park themselves, somehow, even if I cut the power.
