Attempted to wipe 2nd disk, no longer shows up

Heyo, so I tried to wipe my 2tb HDD yesterday and now it no longer shows up

To do this I used a wipe command through terminal. It was going slowly but after it hit 100%, it just kept going
I quit it at 115% because I didn’t know what it was doing, and at the time I could still see the drive in Thunar, just empty. So I made sure games worked and then went to bed

When I wanted to make it mount the drive on start up today, the drive was gone.

Here’s a log I made using the log tool https://clbin.com/uDERo

I feel like I misunderstood what wiping does and have made the drive unusable

You probably need to create a new partition table and partition. Install GParted (or another partitioning app) and create partitions on your drive all you want. Male sure you are modifying the correct drive.

The output in your log shows two devices.
Was it a third drive you tried to wipe?

Looks like the Microsoft partitions on sdb have been wiped:

Do you have anything worth saving in partition /dev/sdb3? If not, you can use e.g. gparted (as suggested above) to re-format disk /dev/sdb. After formatting (and partitioning?) you should see the disk and partitions e.g. with command

df -hT

Thanks guys, this helps a lot
I’ll look into gparted ASAP

I think I might still have had my USB plugged in at the time of the log, so maybe but I’m not sure

Oh I just read the log again, and I completely read past the fact that it sees the second drive as 2tb. That’s absolutely not a USB lol my bad

/dev/sdb was the one I tried to wipe

Try the suggested Gparted!
