I've never, ever seen any sort of switch on a USB (Thumb) Flash Drive. Unless there is an actual switch, then the write protection notice is likely a file system compatibility issue. I commonly transfer data-USB Flash Drives between Windows 10, macOS, Ubuntu Linux and Android cellphone, but they are not always compatible. I suggest finding a repair utility and then reformatting the USB Drive. Actually, 128GB is rather large for a simple Linux install. I would recommend 8 or 16GB. 128GB has to use exFAT, whereas 8 or 16 GB can be formatted plain old FAT. 3GB Flash drive? Does such an unEVEN thing (pun intended) exist? They typically come in multiples of 2, 4, 8, 16, 32, 64, 128, 256. . . .I'm really glad you said this.
I can't believe all the obstacles I've had to leap over this past year. Seems like one thing after another, after another.....
Can it be done with a 3GB thumb drive?
I ordered an Amazon Basics high speed 128GB thumb drive in May specifically to get Linux. It sat unopened in my desk until last night. It's "Write Protected". It has zero used space and ZERO available space. I don't think I can return it and I don't feel like messing with it.
"Messing with it" is a toned down version of what I would actually say. The word I prefer starts with an 'F' and is much more satisfying to say when I'm intensely irritated.
I have thumb drives all over the place. One is a 500GB high speed drive. But of course the only ones I can find have 2 GB, 3 GB and 0 GB
