I have a Sandisk 128gb USB stick with a USB type A and type C output. The problem is that when you plug in the message comes formatting. When I do this, it tells me that the formatting could not be completed. In addition, strangely enough, only 64MB instead of 128GB are recognized. Delete partition does not work either. If someone really has a clue, write. I believe that the problem is with a partition that is not displayed and assigned. I used the USB stick now and then on my cell phone, but also on my laptop.
If it still works on the notebook, plug it in, delete all partitions, unplug it, recreate and format the partitions on the PC and there, this shouldn't work either: dead USB stick
Should the stick have been removed during the data writing process, can you throw it away? It is blocked and can then neither be formatted nor recognized by the system.
I'm sorry for you. LG Lazarius.
Sounds to me like the memory is broken
Sometimes it goes faster than you think.
How old is the stick?
There can be many reasons for downloading and viewing a partition program. Is it free or shareware.
Windows could not complete the formatting - error and cause
