I wanted to encrypt my external hard drive. With "Disks" I chose "Format Partition". Because I had around 500GB of data on it, I let it run over the night. But that morning, it still didn't finish. So in my impatientness, I just unplugged the external hard drive and the I deleted all the partitions on it. Now, I'm left with one partition (Free Space - 1GB) and I can't chose "Format Partition" anymore, nor does the external hard drive show up in nautilus...

Can anyone help me solving the problem?

Thanks in advance!

EDIT I think I need to reset the external hard drive comlpetely. If I want to create a new partition on it it says: "Error on creating partition on /dev/sdb: Failed to meet partition size on device '/dev/sdb' (usdisks-error-quark, 0)"

You can try zeroing the drive, see if it help. I once restored a usb flash drive I found on garbage can using dd. – Liso Mar 26 '19 at 07:04
