[kwlug-disc] Using mSata drives

First, why do you want swap to be used at all? If it is used, it means RAM
is not enough, and you get really bad performance on spindle disks, less so
on SSDs.

Second, if you are using swap a lot, then it would shorten the lifespan of
your SSD.

Third, yes, please try parted as the message says. To do this, just type:

sudo parted

Then enter:
print devices
You will see all the drives that parted knows about.
