If you want LZO compression, as you specified:

           /dev/sdc /path/to/mountpoint compress=lzo,noauto,users,user 0 0

Better yet, if your btrfs is actually on /dev/sdc right now, let's get 
that fstab entry mounting it by UUID instead.

           ls -l /dev/disk/by-uuid | grep sdc
           lrwxrwxrwx 1 root root 10 Jan  3 09:40 
12345678-9abc0-1234-5678-9a0123456789 -> ../../sdc

So then:

           # this is not a real UUID, you need to check 
/dev/disk/by-uuid on your machine for a real UUID
           UUID=12345678-9abc0-1234-5678-9a0123456789 
/path/to/mountpoint   compress=lzo,noauto,users,user   0   0

This is EXTRA important with a USB drive, since it's HIGHLY likely it 
won't always be on the same physical devicename.
