Cannot format usb as FAT

I'm running fedora 18, if you need any other information let me know.

I had this problem with my previous usb drive which is why i purchased a new device. I cannot format my usb drive as fat or ntf, I can use the command:

Code:

mkfs.ext4 /dev/sdb1

to format my drive, that works.

When I run mkfs.vfat I get different output:

Code:

matthew@Fedora ~$ sudo mkfs.vfat /dev/sdb1

mkfs.vfat 3.0.14 (23 Jan 2023)

mkfs.vfat: /dev/sdb1 contains a mounted file system.

matthew@Fedora ~$ sudo umount /dev/sdb1

umount: /run/media/matthew/LIVE: not found

Gparted won't even let me unmount the usb drive.

Disks(gnome tool) will also allow me to format the drive as ext4 but not fat/ntfs.

I don't know why It's trying to unmount LIVE, that was what the usb was when I installed fedora's live installer onto it. after that I tried to format the drive as ntfs to put my windows iso contents onto it which is what ended up causing the error.

Also, fdisk isn't of any help either, just trying to create a default primary partition.

Code:

WARNING: Re-reading the partition table failed with error 22: Invalid argument.

The kernel still uses the old table. The new table will be used at

the next reboot or after you run partprobe(8) or kpartx(8)

Syncing disks.

Rebooting or running partprobe isn't of any help either.

Any suggestions on fixing this would be greatly appreciated.

What is the output of "mount" and "df"?

mount output:

According to mount and df you have no root to the filesystem ( / )
Have you installed Fedora to your system or are you still running it in live mode (if live, what device contains the live image)?

Fedora is installed on partitions /dev/sda1 and dev/sda2, here is my fdisk -l output

Was the live USB in the machine when you last started it up? It doesn't look like things are mounted correctly. I would power off the system, remove the USB, start it up, and then once it's booted into the OS you can re-insert the USB and try your formatting.

I couldn't fix the issue. Instead I used the gnome application disks to format my disk as ext, then used the fedora liveusb creator tool to install fedora back onto the usb stick. I ended up with everything working the way it should now.

I still wasn't able to format the usb stick to fat with linux, had to do it on windows(which had no problems). I may report the bug to fedora.

Thanks suicidaleggroll for the help.

A mod can close this thread now.
