hard disk issues caused by power supply - is hard disk also dead?

I've had a number of hard disk issues recently including both of my hard drives. They were disappearing (and sometimes reappearing), and I fixed the problem by plugging them into a different outlet of the power supply (and also moving one of the data cables, but both drives were showing issues so it seems unlikely that this was the problem). I will replace the power supply, and I know that dodgy power supplies can kill PC components by overpowering them. Could I have that problem here? If so, I assume this has shortened the life of everything, but the hard drives seem most critical. Would I also need to replace other parts to e.g. stop the new drives from being damaged?

Both disks appear to work, but both had partitions that required manual fscks. One of them normally takes 20 min to fsck - it's only thrown one error but it's been running for over 24 hours and is still checking inodes, blocks and sizes. I've tried sending it SIGINT and SIGTERM, but that's done nothing - I think it may be frozen but I don't want to send SIGKILL if I can help it. Does this mean the drive is bust? It's been running silently for at least 12 hours, and I've set /proc/sys/kernel/printk to '5 4 1 4', so there don't seem to be major issues?

Not sure if it's needed, but for context: before I managed to fix the issue I ran quite a few fscks (and turned the 'quiet' kernel option off for some of them). I photographed the screen with my phone and can type out the issues if it will help - they were things like:

COMRESET failed

EXT4-fs error __ext4_find_entry

status: { DRDY ERR }
error: { UNC }

So if anyone could help my understand whether I need to replace my hard drives / other components, and whether this fsck will ever finish, it would be a great help!

You could check the disk status preferably from a live system booted from usb and on a different PSU…
Also upload the error screen iamge, but you can very much receive bus errors w/o actual damage to the drive. It might just be underpowered.

Thanks for the help. I unplugged my more important (and more damaged) hard drive, and have been running off the other one for the time being. Finally got new powersupply and bootable USB, have only tested the less damaged one so far, but I got a read failure. I guess I need a new drive.

In case it's still relevant, here are some screen photos from before (I didn't post them before because my phone camera's crap, they're hard to read.
