I use a usb pen drive to transfer files between my Slack system and my
antique Win 98 computer which has a inkjet color printer.
Unfortunately in a fit of madness I reformatted the pen drive to
linux. Now I need to put it back in FAT format again so that the
antique can recognize it. . It is /dev/sda1. I tried
fdformat /dev/sda1
but it balks because of no format specified. The pen drive is 256mb
capacity.
