USB Drive Not Showing Up

jp flag

I just bought a new Lexar 128GB thumb drive. My system was using it at first and allowing me to transfer data to it. All of a sudden while using it, it stopped working. I am using Ubuntu 22.04. Is there any way of correcting this? Without replacing? I have tried on other systems as well to achieve this to include Windows versions 8-11 and Ubuntu 20.04.

how is the thumb drive formatted ? ext3, fat32, vfat for example. Did your system ever go to sleep while copying a lot of files ?

@mondotofu it is fat32, computer had not fallen asleep while copying files, it just as it was copying approx. 32G data onto a 128G drive stopped recognizing the device.

@Pilot6 I would like to be able to at least retrieve the data that I had put on it. Are their any forensic tools that could help recognize it at least long enough for me to retrieve the data from it

Plug the drive into a computer running Windows and run `chkdsk Z:" where Z is the USB drive.

@user68186 That would requie the computer to be recognizing the device. is there a way of putting a variable there to have it look for additional drives?

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, find a solution. -- There are problems if no computer can see the USB drive as a 'mass storage device', but if you are lucky there is 'only confusion'.

There are as many as 1/3 of USB drives on the market today that are counterfeit. And some are certified for a given capacity, but scammers will paste their own labels advertising twice the capacity and sell them at a bargain price to move them. So beware.

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
