Oh I see.

That really I didn't know. I would just mount it in /mnt/pendrivechecks

Yes.

i) How to know the partition name while inserting usb pen drive?
Running "fdisk -l" or "fdisk" yields, but with "sdb" not written 1 or
2 at the end of 'sdb', and for sure, 'sdb' is the pen drive partition
name. Or the command, "dmesg | tail"?

ii) After that, I have to unmount it, using the command "umount
/dev/sdb" so that it could be formatted.

iii) Now for formatting, I would have to use either vfat or ext3. But
how to know whether to use the former or the later?

iv) I guess it would be correct:

$ umount /dev/USBPARTITIONNAME

$ /sbin/mkdosfs -F 32 -n usbdisk /dev/USBPARTITIONNAME

Where, USBPARTITIONNAME is what I would be getting from query i)

I didn't use sda.
