Safe removal of USB storage - suggestion for a future LL release

[m654321]

As in Windows OS, and at least one distro that I know of (Zorin 9), there is an option to mouse-click on for safe removal of USB storage devices.

For example in Zorin 9, at the file manager window, I right-click on the icon for the USB device concerned and a drop-down box will appear - one of the options in this box is safely remove hardware.  When I click on this option the device activity ceases (as you would expect), reflected  by it's blue indicator light going off.

In LL2.8 the options in the drop-down box mentioned above, include unmount and/or eject - either one separately , or unmount followed by eject,  don't appear to stop activity of my external USB drive, i.e. the USB device's blue light stays on. To make LL newbie-proof could we have this safely remove hardware option at some future date?  Obviously I don't want to remove a storage device until it is turned off as I may lose any data still being written...

In the meantime is there a terminal command to safely remove hardware?

Thanks
Mike
