Problem with Recheck torrents data

[xaaru]

Hello.
I have a problem - I use Deluge on Laptop with Linux OS. I place downloaded data on my USB-HDD. Sometimes My USB-HDD disconnects when Deluge is Running, and it begins to recheck all of my downloaded torrents. So it's a big problem for me. I didn't find any options to disallow Deluge recheck data, when torrent's destination folder is inaccessible.
How can i solve this problem&

Pause the torrent

of course, to pause torrent is the solution, if i decide to disconnect HDD. But sometimes it happens not depending on me. for example, my child touches the cable, and HDD disconnects from the notebook, or i move notebook, and something happens< and HDD is unmountin, and i have to rechek all of my downloaded torrents

Maybe it's possible to add an option, to choose what to do, if Deluge can't access torrent's data - recheck them, or leave how they was before...
