I have USB pendrive formated to fat32 or ntfs with photos. Windows see brokend pendrive and can't repair it. Ubuntu doesn't 'assign letter' at all. I think there could be broken partition table or HW misstake on memory chip.

Can anyone help me how can I try to repair partition table on Ubuntu? Here are my attempts to mount disk or identify it anywhere in system.

    FAT32 and particularly NTFS should only be corrected with Windows tools. This has nothing to do with Ubuntu. Ubuntu is not a free tool to fix Windows. – ChanganAuto Dec 09 '21 at 12:17

    If it's a thumb-drive; that's not *long-term-storage* media but a cheap consumable, so it's possibly a faulty thumb-drive, and just switching to your a new thumb-drive on which you copy the wanted files from your backups is the usual fix. Thumb-drives aren't a safe/secure storage medium; being a cheap consumable (*with no error checking on them anyway*) – guiverc Dec 09 '21 at 12:24

    That could be a broken partition table, which windows can't fix. You could try imaging the drive and then use testdisk or something to try to recover. – user10489 Dec 09 '21 at 12:24

    You can analyze the problem according to [this link](https://askubuntu.com/questions/144852/cant-format-my-usb-drive-i-have-already-tried-with-mkdosfs-and-gparted/933035#933035) and if you are lucky solve it. **But first, if there are important files, try `testdisk` and `photorec` from https://cgsecurity.org**. I have used `photorec` successfully. – sudodus Dec 09 '21 at 12:35
  • Can you explain what the problem is? Your outputs show that Ubuntu has no problem with this drive and is correctly assigning "a letter" to it, calling it `/dev/sda`. You can see it in `/dev/disk/by-id`, and in the output of `lsusb` and in the output of `lshw`. – terdon Dec 09 '21 at 13:45
  • Thank you all for your answers. We tried to connect/disconnect pen drive many times at Windows and on 20? try it has connected. Videos are unreadable, some photos broken. But many of then was saved. Thank you for direction to try Windows on this proprietary think. Closed. – ShippeR Dec 16 '21 at 10:03
  • @terdon yes it was about /dev/sda – ShippeR Dec 16 '21 at 10:04
  • So what's the problem? You say that "Ubuntu doesn't 'assign letter' at all" but your output shows that the drive is seen and assigned as `/dev/sda`. – terdon Dec 16 '21 at 13:07
