/dev/sdb1:
setting readonly to 0 (off)

The disk to be formatted is sdb1

Thanks in advance

Actually this tool only works for mmc which means that you've to connect it only through the card reader that doesn't connect in any way to the usb ports.

You may use a card reader or insert card directly if ports available. USB type readers won't work as it creates the location like dev/sdb like yours did.

Instead it should have came up with something like dev/mmcblk...
Which only comes when you directly insert card or reader into the system.
