I Can`t Format the microSD for flashing Linux.

I use usb microSD card reader. Mount it to /media/disk

run script ./format_sd.sh -d /media/disk
But it return:
/media/disk is not a block device,
please specify the device file representing your SD card

What I do wrong?

Just as the error message suggests rather than the mount point /media/disk you should specify the raw block device file (e.g. /dev/sdb). Please have a look at the df and/or lsblk output to find the exact device representing your microSD card.

Thank you.

An alternative to direct get the device block mounted:

mount | grep "/media/disk" | cut -d " " -f1
