First of all, I'm very new to linux as a whole, so please bare with me on that!

As stated, the issue is ubuntu 16.04 doesn't detect (nor mount of course) an external HD when i plug it in. I actually reinstalled the same version, and the problem remains. However, when I try it on a laptop with ubuntu 14.04, it works perfectly. On this same laptop I also have windows 7, and it also DIDN'T detect the drive.

I've been trying the different solutions proposed in this site and others for issues with mounting external drives, but so far no luck. Through fdisk command in ubuntu 14.04 I manage to confirm it's ntfs, just in case.

It doesn't even show up on fdisk -l, df or lsblk, so I can't use the "manual" sudo mount , because apparently technically the device doesn't exist for ubuntu (at least it has no assigned label/direction, the message I get is that there is no such device). I even tried "faking it" (wrote /dev/sdb since the other hd is sda, then tried with sdb1, still no luck).

When I try dmesg, however, it DOES show up there. I copy output below:

[   48.663473] FAT-fs (sdb1): Volume was not properly unmounted. Some data may be corrupt. Please run fsck.

I think that's all the relevant stuff.

I also read a suggestion about fixing corrupted filesystems with fsck, but I get a rather alarming warning and I don't want to lose the data already in the ext HD. Besides, it won't let me direct the command at the HD specifically, since there's no "sdb1" or whatever that I can use as argument.

I don't know if that might be it, but the computer I've got the ubunte 16.04 on is an old one, only with usb 2.0 ports.

Anyway, that's all I've got so far, thank you for any help!!

It sounds like we are talking about 2 different computers as opposed to 16.04 vs 14.04, I see mention of chrome in dmesg, it may be that this computer doesn't have enough power to supply an external HD judging by dmesg getting to the point where it says [sdc] Spinning up disk... but then gets no further, if your external HD does not have it's own separate power supply then this may explain why it's not working on what I'm guessing to be a chrome book as opposed to a laptop that probably supplies more power to the USB port.
