Nope, you didn’t break anything. For some reason, they called it ‘smartmontools’, so use that instead of smartctl in the apt-get command.
(Actually, at one level smartmontools makes sense as a name, but it makes remembering what to type a bit harder when doing the apt-get…)

SMART Error Log Version: 1
No Errors Logged
…
Notice that we have ‘pre-fail’ and ‘old-age’ above, and especially the ‘Overall-health self-assessment’. That one is the one that the BIOS checks to see if the drive is dying.
The important ones in the above list, from the point of view of failure alerting (IMHO), are reallocated sector count (5), raw read error rate (1), attributes 10-188, hardware ecc recovered (195), reallocated event count (196), offline uncorrectable (198). (If you see a lot of UDMA CRC Errors, that’s probably a cabling issue, assuming I actually understand what the vendor is using that attribute for!).
First, let me back up and say that, since there were no errors logged, this drive is PROBABLY happy and not going to fail ‘real soon’. But, the raw read error and seek error rates aren’t as low as I’d like. On the other hand, this IS a rotating drive, so maybe that’s normal. On the other hand, I compared that drive with another rotator, and that other one has 0 raw read errors, 0 reallocated sectors, 0 seek errors, 0 reallocated events, 0 offline uncorrectable, etc. The second one has been running 21,596 hours.
A third drive has similar zeros for errors, but yet has had 8 errors:
ATA Error Count: 8 (device log contains only the most recent five errors)
…
Powered_Up_Time is measured from power on, and printed as
DDd+hh:mm:SS.sss where DD=days, hh=hours, mm=minutes,
SS=sec, and sss=millisec. It "wraps" after 49.710 days.
Error 8 occurred at disk power-on lifetime: 5610 hours (233 days + 18 hours)
When the command that caused the error occurred, the device was active or idle.
After command completion occurred, registers were:
ER ST SC SN CL CH DH
-- -- -- -- -- -- --
84 51 18 2d aa 03 e0 Error: ICRC, ABRT at LBA = 0x0003aa2d = 240173
Commands leading to the command that caused the error were:
CR FR SC SN CL CH DH DC Powered_Up_Time Command/Feature_Name
-- -- -- -- -- -- -- -- ---------------- --------------------
ca 00 28 1d aa 03 e0 08 48d+06:41:01.204 WRITE DMA
Anyway, watch these numbers, and if they start changing much start looking for a replacement disk ☺ If you start getting lots of errors in the error log, that’s probably significant also.

You might want to check syslog (or messages) to see if the drive is getting errors. (which is to say, getting ready to die)
Or use smartctl -a to see what the SMART attributes say (look for the ‘pre-fail’ attributes). Or, best, do both.

I ran fsck. It just returned through. So then I reformatted it with gparted. So all is well (I guess). I did have to restart the computer after the reformat though (don't remember why) but everything seemed okay. Oh yeaaaaa! I think I had to restart it because it would not unmount and I figured I would try to restart it and if it would gracefully do so it would be good. And it did and upon restart the drive auto mounted.

Ok, unmount the drive, then run
Sudo fsck <your device here>
When completed, remount and then try to remove the files using:
Sudo rm -rf <name of files here>
