Unable to remove write protection from pen drive

I have scandisk 16GB pendrive which accidentally got write protected(s/w as there is no hardware write protection feature availiable).

I have tried sudo hdparm -r0 /dev/sdb1 still it is write protected.

What other ways availiable to remove the write protection?

Try this answer by Angel Genchev: USB turn write protection off

To turn off disk device`s write protect, we use the low level system utility hdparm like this:

sudo hdparm -r0 /dev/sdb

where we asume that /dev/sdb is the Physical disk device we're working on. If the device has partitions that are mounted as read-only, you should re-mount 'em as read-write in order to write data to them.

Hope that helps.

You should run sudo hdparm -r0 /dev/sdb rather than sudo hdparm -r0 /dev/sdb1. So run your command but without the 1 at the end. You specify the device itself as a whole and not the partition number.
