[CoLoCo] I'm confused about how the disk works

[NICK VERBECK]

I'm having what seems to be the same problem on my laptop as well.
I'll have to check the swap disks and see if its the exact same thing.

You may look into using UUID's in the /etc/fstab for mounting the
swap. That maybe where the problem is at. I use to have problems with
my tower where one hard drive wouldn't mount to the same point every
restart. Converted to using UUID and now I haven't had the problem.
