Power outage kicked my external power connected HDD out.

Hey guys,

I messed up my install. I should've debugged better before taking some knee-jerk actions. So last night, we had a storm which caused an area outage and I didn't feel too good about it. Next day when I tried accessing Plex running on one of my server, I noticed that none of the media was showing up. I opened the Proxmox UI and saw that one of the HDD had a small question mark icon next to it, and on clicking anything other than the "Summary" tab, it was showing a "Input/output error". So I ran to google with it, and the answer seemed to be close to what I suspected. It was a hardware fault. I thought of it as no biggie and unplugged the hard drive, waited 5 seconds and re-plugged it. Bad Idea! But the error didn't go away.
I have been debugging on google for couple of hours now thinking that the HDD was corrupted to save whatever I could. While doing that, I was constantly booting up the VM after every possible fix. And it was then I noticed, while booting up the VM was trying to do something. It was trying to mount the UUID of the disk I specified in the fstab file. And after 1:30 min it times out and wouldn't boot. So now, not only my plex-media is gone, I can't boot the server itself. It had a bunch of other services running on it. If anyone knows how to fix the fstab file on an arch linux server please let me know, as that might save it? I tried going into the GRUB menu but there just two options within "Advanced options" which only let me edit a few configuration, non of which were the fstab ones.
And then it hit me, had I just logged in to the proxmox node and checked first if the drive was mounted or not, I could've fixed it with a single command! Unplugging and replugging it has given it a new UUID so fstab isn't picking it up.
For now I've mounted it again. I did a bunch of `df` and `du` to see that there is a qcow2 file which I'm using with the following command to import in a new VM from scratch. I don't know how it'll go. But being a noob, I wanted to ask here as the usual google search I can't find the specific situation I've gotten myself into.

Thanks for reading.
