While installing esx11, I accidentally disconnected the usb drive from the Kronos (it was attached to an extention cord and I moved things around), and now the installer hangs at 28%. Reconnecting it doesn't make the installer continue, so now the machine is basically stuck.
Since it's actually been writing files, I'm afraid turning it off now could cause problems.. But there's not much more I can do now, it's unresponsive (alhough I can still play a piano tune

What to do?
