Thanks Sarah for you help. Another issue popped up for me. I noticed when I suspend having a usb3 filesystem mounted (ie mount /dev/sdb2 /mnt), when the system comes back up, the filesystem is remounted onto /media (probably a distro thing) but more importantly it comes back as /dev/sdbc (note the 'c' and not 'b'). Looking into my previously mounted /mnt directory yields an i/o error (probably because it is now under /dev/sdc). Unmounting everything and remounting 'mount /dev/sdc2 /mnt' (using the new letter 'c' instead of 'b') works fine and no data loss seems to occur. Just thought it might be annoying and was wondering if you had any ideas on that?
