#Partition does not get deleted, despite no error being given

OS: Linux Mint 20/ Manjaro 22

Problem:
I can not delete the partition on my usb-stick, nor any data on it. If i delete files or partitions they disappear until i unmount and remount the usb-stick, at which point they are there again. I do not get any error messages whatsoever.

What i am doing:
I want to use the ext4 file system on my usb-stick. I tried using GParted and gdisk to delete a partition. Both don't work on a manjaro or mint os. I am 80% sure that the stick got partitioned on mac-os, after which the problem started to occur.

The usb-stick does not have any data on it that i need, it can be completely nuked in whatever process to solve this issue. I attached a short video to show how GParted and gdisk fail without an error of any kind

Is there some kind of readonly switch on the USB stick? And is it usable with another OS/system? Like just throw another file on there for testing. No idea what would be causing it but I'd just dd it and see if that does anything

what is the ⚠️ in gparted about?

is the usb from a reputable brand?

#

sounds similar to what happens with fake usb drives

#

If this is an aliexpress or cheap ebay drive, that's probably what's happening

i would imagine it makes data rescue unavailable, not deleting the partition. The usb stick is an intenso slim line 128gb

is there anything interested that shows up in dmesg?

i got

a bunch of times with different sector and flag codes as well as
"[173500.781719] Buffer I/O error on dev sdc1, logical block 30207456, async page read"
with different block numbers, and
"[179103.970942] Buffer I/O error on dev sdc, logical block 62770, lost async page write"
again with different block numbers

that seems pretty indicative

#

so you tried two different computers, i assume you tried basic stuff like switching usb ports and restarting the computers

#

seems like the usb drive is a lemon

i give up, nothing changes what is on that usb. I even tried overriding the stick by turning it into an encrypted volume, but after remounting it, everything was like before again.
