I was trying to flash my pendrive with Ubuntu 22.04 using Rufus and tried to add persistence partition size to it, Not sure why it didn't flash properly and gave me error as device not found. So I thought I will format it and flash it normally. When I tried to format it, from then on I was not able to see the drive. (This entire above instructions were done in windows 11). The pendrive is brand new, it's been around 3 days since I bought.

I thought I can try something in Ubuntu to make it work, So far I have tried different methods to make it work, but it didn't work

I have tried all the methods that are mentioned in this thread : Can't format or access a detected USB Key. I get the exact results mentioned in the question, and no other answer resolved my issue.

Additionally GParted doesn't show my pendrive. And from the built-in Disks application shows my pendrive, but there are no options to perform on it.

disks application SS 1

disks application SS 2

I have also tried using mkusb, tried all the options:

When I choose restore to SSD it gives this output:

restore to ssd output

When I choose wipe first megabyte it gives this output:

wipe first megabyte output

When I choose "wipe the whole device" it gives this output:

Wipe the whole device output

Not sure why it didn't flash properly and gave me error as device not found.

It didn't flash properly because your hardware was already defective, and what you saw was the result of that (i.e. the error messages were a consequence of the already existing hardware issue and not the cause of it).

Please be mindful that the flash memory used in consumer USB drives is a lot more unreliable than people realize and it tends to fail at a much higher rate than owners of such devices expect. This has nothing to do with the application being used, or the type of device you create (such as one with or without persistence) but everything to do with the unreliability of the technology being used. Flash memory cells have a limited number of rewrites and, because it's governed by statistics, even if the datasheet may indicate a mean of 10,000 rewrites or more, if you happen to be unlucky, it may be a lot lower than that for the flash memory cells of your specific drive... And when that happens then, there is not much you can do software wise to try to "fix" what is essentially an irreversible hardware issue.

So, typically when an application like Rufus reports an error and then you find that your drive is no longer accessible, it simply means that Rufus was the first application to detect that your hardware was defective. And if you tried to reformat/repartition your drives using various utilities and you weren't able to recover it, I'm afraid that you're just going to have to purchase a new drive.
