Virtual pendrive: image

[Narcis Garcia]

I need to emulate an USB stick with only image file backend.
I've tried this:
$ qemu-system-x86_64 (...) -device virtio-scsi -drive
file=pendrive.img,media=disk,discard=unmap,detect-zeroes=unmap,index=1

But all Windows applications in VM detect it as a hard disk. I need to
use some of them dedicated to format USB pendrives.

How can I do it with qemu command line parameters?

Thank you.
