All of a sudden, when booting my Parallels VM; I get the error "Unable to connect Hard Disk 1" and I cannot boot my VM -- I've tried a few solutions I've seen around - but I don't use Boot Camp, and it seems the only people having the issue are boot camp users. Nothing works - I've restarted, restarted PD5, tried to revert to snapshots (I take one every 2 hours; turns out, they're useless in this case).
