so I bought a compact hard disk but find that its a flash drive (lsusb shows it as Integrated Technology Express Chipsbank CBM2199 Flash Drive).

Using the Disks application shows it but doesn't know about the partitioning and contents are unknown. Strangely it shows two partitions, one is unknown and 17MB and the other is 8.4TB

fdisk -l shows /dev/sda as Disk model: SSD and has /dev/sda1 and /dev/sda2 correctly with sectors

I've formatted it exFAT which I thought should be usable, but it seems not

I read this thread: 22.04 does not include exfat-utils

and apt-list shows that exfat-fuse/jammy and exfatprogs/jammy are present

So, why isn't this working?

Based on my other readings outside of here I believe the drive does not work with Linux and so I've solved the problem by returning

My thanks to the people who took time to answer the question, but ultimately there was no time cost effective solution

Thanks

Likely, the drive is fake. I recently received a similarly fake drive from a seller on AliExpress that claimed to be 2TiB with USB3.1, but was in reality only 64GiB with USB2.0. You can analyse the drive with f3probe https://www.linuxbabe.com/command-line/f3-usb-capacity-fake-usb-test-linux

$ sudo f3probe --destructive --time-ops /dev/sda
F3 probe 8.0

Bad news: The device `/dev/sda' is a counterfeit of type limbo


You can "fix" this device using the following command:
f3fix --last-sec=125435903 /dev/sda


Device geometry:
                 Usable size: 59.81 GB (125435904 blocks)
                Announced size: 1.90 TB (4075520000 blocks)
                        Module: 2.00 TB (2^41 Bytes)
        Approximate cache size: 511.00 MB (1046528 blocks), need-reset=no
           Physical block size: 512.00 Byte (2^9 Bytes)


Probe time: 38'46"
 Operation: total time / count = avg time
      Read: 34.12s / 2097721 = 16us
     Write: 38'10" / 7327949 = 312us
     Reset: 0us / 2 = 0us

and checking the bcdDevice number in dmesg or lsusb.

You can install the ChipsBank UmpTool for your USB device type from usbdev.ru. For your case, it should be type CBM219X. After installing, you can simply click the start button if your device is detected and wait for the process to end.
