dmesg -w
usb 1-4: new high-speed USB device number 6 using xhci_hcd
usb 1-4: New USB device found, idVendor=0011, idProduct=7788, bcdDevice= 1.12
usb 1-4: New USB device strings: Mfr=1, Product=2, SerialNumber=3
usb 1-4: Product: Mass Storage
usb 1-4: Manufacturer: Generic
usb 1-4: SerialNumber: 2FC4D0FC

In

fdisk 

it doesn't show up.
Here USB stick not detected and in other answers the code after the device lists a name

sd 5:0:0:0: [sdc]

I don't have that, so how can I use the device? With the ID 0011:7788?

Thanks! Hope I got the formatting right.

Re: How to mount USB

Thanks @jonno2002. The tool you linked is windows based, so went on to check the pendrive on a win machine. Works fine. fat32 and has files on it.
I should be able to mount it on linux.

Re: How to mount USB

Please post the output of lsblk -f with the usb drive plugged in .

Re: How to mount USB

In that case we'll need to see full journal / dmesg output (both while running as root/with root-rights. )

See https://wiki.archlinux.org/title/List_o … n_services for methods to upload text to public places.

You're missing the point:

These drives are fake, a scam. Fraud.

The firmware is manipulated to suggest more capacity than exists and the tool in the link jonno2002 sent you is used to "reformat" the drive (reset the firmware) to its legit values.
Use them at your own risk and also notice that they're highly vendor specific.

About using the drive on windows: because of the oversold data there's a high risk for data loss when using more than half or maybe even a quarter or less of the capacity because at this point the drive will write sectors that are marked free but actually hold data what will lead to data corruption or loss or a corrupted filesystem.

If you can reset the drive to its actual (smaller) capacity, you can use that. Though, quite frankly, I wouldn't trust it too much still.

@seth understood!

For future reference,

journalctl :

dmesg

As a last try I did as advised here: https://superuser.com/questions/1206664 … -mass-stor
That did nothing

Re: How to mount USB

Just as a sanity check, you can "sudo modprobe -v usb-storage"?
