Is there any risk in keeping the data cable for a SATA disk connected when its power cable is disconnected ?
There are several projects on the web to switch between disks by connecting them to individual SATA ports and switching on/off the power to one or more.
Of course the switching is done when the PC is powered off and never when the disk is in use.
But I wonder if the unpowered logic on the disk or the host may be damaged by doing that.
 

If PC is turned off (motherboard is off, not standby state), then there is no problem to do that with HDs.
 

I mean that the disk will be connected by the data cable when the PC operates normally. This is to switch between disks with different operating systems. For example disk A is connected and powered on and disk B is connected but un powered. Then I could turn the PC off flip a switch and turn the PC on back again. with disk A no power, disk B with power.
