Andriy Gapon submitted an equivalent review request time ago: https://git.reviewboard.kde.org/r/105432
It solves the same issue (I was not aware of it), introducing a function which was proposed for the Solid API. Apart from the specific code, for which you seem to trust our judgement, what's your preferred approach? I admit that at this very moment I am not aware of other places which require that function, but I guess there could be some (I may have seen one where CD drives need to address their parent storage drive).

By the way, would you approve a change to set both individual Removable and Hotpluggable properties? This would make the dataengine more consistent, while it's the plasmoid which has to check for both the properties to identify removable devices (I've read the HAL spec - which I think can be a reliable reference for those properties - and yes, one should not be set when the other one is, so we're handling them in the wrong way).

This works fine with UDev, but not with HAL, which can have (at least on FreeBSD, where I'm testing it) a StorageVolume device in the middle. Going up the whole tree of the Block device ensures that we eventually get to the StorageDrive one to fetch the correct removable property.
