18 exabytes written to Boot Device?

[Thedinggo]

I have some images in an imgur link. Not sure how it happened, Got home from work and seen my theme was set back and was missing the dockers tab an was about to restart then i noticed the amount of data writes to the boot device. I'm pretty sure the usb from unassigned devices is the boot device i'm going to restart after makes this post and see if it fixes this(good chance it wont though). If anyone knows how this could happen, Or of how to fix it. I would really like to know. I also attached the diagnostics report, Still have one from 2 months ago as well if it would help at all let me know.
thank you.

Stupid large stats numbers usually mean a dropped device, and it's what happened here:

 

Apr 13 18:22:15 Tower kernel: usb 3-3: USB disconnect, device number 3
Apr 13 18:22:15 Tower kernel: sd 0:0:0:0: [sda] Synchronizing SCSI cache

Flash dropped, make sure you're using a USB 2.0 port and/or or try a different port.

I didn't see that in the logs, but had a feeling it was a dropped device, only after the restart and everything was back to normal, Next time the system is rebooted i'm going to move it to another usb2 port. Thank you for the help and the insight in this.
