Advice? External USB harddrive accidentally unplugged (no activity at time). Re-plugged, but mountpoint/findmnt/lsblk disagree if mounted?

[sorry, brand-new user, not sure how to format/tag]
So I just accidentally bumped and and unplugged the cable on an external USB harddrive.
- There was no activity at the time.
- It's btrfs
---
I just plugged it back in, and...
- `mountpoint [[path]]` #=> "`[[path]] is a mountpoint`"
- `lsblk` doesn't show it as having a mountpoint
- `findmnt` #=>
Code:```
TARGET SOURCE FSTYPE OPTIONS
/ /dev/sda3[/@/.snapshots/1/snapshot] btrfs rw,relatime,ssd,discard=async,space_cache=v2,subvolid=266,subvol=/@/.snapshots/1/snapshot
[...]
[...]
[...]
[[path]] /dev/sdb1 btrfs ro,nosuid,nodev,relatime,space_cache,subvolid=5,subvol=/
```- but
` sudo ls [[path]]`
#=>
`ls: reading directory '[[path]]': Input/output error`
---
What should I do/check?
Like, I am *aware* of `fsck`,
but I don't know anything specific about how/why to use it...?
Basically, what are my unknown-unknowns here?
