[Solved] Is this hard drive failing?

Solution

Yeah, the drive is dying. As suggested by @nous, and @Granixo, I ran a S.M.A.R.T. test (the , and received the following report:

Original Post

I have a pulled hard drive from an old Western Digital external hard drive. I connected it to my desktop to see what was on it, and, after running fdisk -l (which took a weirdly long time to run while also keeping one core at 100%), it gave the error message:

<pre style="background-color:#ffffff;">
<span style="color:#323232;">The primary GPT table is corrupt, but the backup appears OK, so that will be used.
</span>

However, trying to mount it resulted in another error saying that the drive doesn’t exist. Looking at dmesg reveals a ton of other errors like the following:

Is this drive dead? Is something just corrupt? If there is data on it, would it be straightforward to pull it off?
