Hard drive shows up for `lsblk` but not `fdisk`

Question

I have a hard drive (/dev/sda) that is visible when I run sudo lsblk -f, but not when I run sudo fdisk -l.

What could be causing this?

All the google results I could find were about drives that were not listed with either lsblk nor fdisk.

edit to add:

When I run sudo fdisk /dev/sda, I get the error

fdisk: cannot open /dev/sda: Input/output error

When I try running sudo fdisk /dev/sda, I get the error fdisk: cannot open /dev/sda: Input/output error. — PortMan, Aug 30 '22 at 15:59
Additional information: I get an Input/output error when I try to run sudo fdisk /dev/sda — PortMan, Aug 30 '22 at 16:42
Can you add the output of sudo lsblk /dev/sda and ls -l /dev/sda to your question? — doneal24, Aug 30 '22 at 16:58
lsblk is simply interrogating the drive identify, while fdisk actually needs to read from disk. The error you're seeing suggests that your drive may be bad. — larsks, Aug 30 '22 at 20:44

Use gdisk. It should work. This means either the disk is physically damaged, but to the extent that is it sill recognised or that partition table has been damaged in a way that fdisk is not able to recognize. fdisk will not let you in, but gdisk will.

How should gdisk work if the drive is damaged? – stoney Jan 13 '23 at 07:32
