OS doesn't recognize ext. flash drive

Hello, I tried to mount a particular flash drive using the following: sudo mount /dev/sdb1 /mnt/flash, & the following message was returned: mount: /mnt/flash: special device /dev/sdb1 does not exist. What does that mean re a 'special device'? Thank you.

Did you check it exists? ie. using blkid (or equivalent) showed a sdb1 as a valid block device? capable of being mounted.

If you read the reference manual page for mount (man mount) you’ll see it refer to "special block device; as not all devices can be mounted the page refers to block devices as special as they can be mounted)

Thanx, I didn’t do that; I’ll do that now. I referred to Schott’s manual & the LinuxConfig w/s when I encountered the problem.

I find

lsblk -f

convenient to see all block devices.

And please make also sure, that the mountpoint /mnt/flash exists, before mounting.
