None no

Haven't you heared about some kind of device to put between sata host and a disk in order to disconnect SATA cable in a proper fassion? This is very high speed data line and I can't do it just by putting any differential multiplexer. It must be something special for this speed with proper impedance, capacity and hundred more factors. Reconnecting disk to the working computer works. After I dismount VC volume I also unplug SATA and also no problem. For example this: https://addonics.com/products/cc2dt.php...

Yes but if you know you have a disk encrypted and dismouunted it would be safer to power it down. Now I unplug sata when I remember in order to prevent cryptolocker strike but contacts will wear our. Now I built PC with 6 hhds, 2 x raid 1 plus 2 disks for offline backup. And it is a server, I can't go and replug cables... Lets discuss such case with a second semi offline disk.... Maybe I should build a relay module and power down the disk using Arduino over RS232 ? It is a solution but switching...
