I bet they don't...  The Selectric typewriter had a unique feel to it,
no click as the key was pressed down, you just pressed the key down to
the end-stop with a bit of a clack, and the spring resistance was
matched so that didn't hurt your fingers.  You could type really fast
and easily on them.

The sproingy IBM (and others) computer keyboard, which makes a hell of
a racket as a spring suddenly bends part way through the key being
depressed, is an entirely different affair.  And nowhere as good for
fast typing.

As someone who's used both, they are nothing like each other.

Some of the early dumb terminals had great keyboards, somewhat like the
feel of using a Selectric kind of keyboard (tensioned hold-up springs
behind the buttons, actual switches but silent).

If you want a lasts-forever keyboard, you've got about two choices. 
One that no-longer exists, its keys dipped pins into pools of mercury
(silent, and bounce free), or a hall-effect system where the keys whiz
a magnet past a sensor (again, silent and bounce free).

The cheap ones use that plastic/silicon-rubber dome bubbles to hold the
keys up, which suddenly dimples in when pressed.  The feel of that
action is often terrible, but occasionally okay.  Underneath them
there's two common ways of doing the electrical switch:

Pressing two flexible plastic circuit boards together so there's a
capacitive change under the key press.  As grot gets in, or the
conductors get ground, they start to fail, and you have to hit some
keys harder and harder for them to work.  You might also get multiple
key presses believed by the keyboard encoder.

Rarer and older, a conductive carbon pad on the key dome was pressed
across two circuit board traces when you hit the key.  As grot gets in,
or the carbon pad crumbles or gets contaminated with air polution, they
go unreliable.  Though some of that can be cleaned off by disassembling
the keyboard (not a fun task, with a gazillion springs everywhere,
often not actually attached to anything).  I've done that on custom
keyboards which can't actually be replaced any more.

Samsung is also the only flash drive I have come

Speaking of 'a storm on small file transfers", I have a

The getting lost is an issue.  So far only one

Hi Robert,

Do you have any virtual machines running?  If so,
they may be attaching to the USB flash drive.
If so, the host system won't see them.

Also try

   ls -al /dev/sd*

maybe it is not mounting on /dev/sdb.

And worst come to worst, boot off a Fedora Flash
drive and see if your drive in question mounts.

bought this supposedly good HP keyboard about a year ago.  I stopped 
getting their Inland cheap boards, as those were wearing off in a few 
months.  I was more tired of going through the return process than they 
seemed to be with the returns of 'defective' keyboards.  I just want a 
simple USB keyboard that is plugged into my KVM...

It never showed a size, so if there is anything connected to it that still
works, then the controller no longer sees it or knows about it.  The media
removed is what you would see on a device you would plug a sd memory card

Is this dead?  Is there some other tool I can use to get it working?  If
there was ever anything on the drive, it would only be a copy of
something, so nothing to try and recover.  Other than a nice 32G USB stick.

thanks!


   Did you check dmesg for error messages associated with it?


just reinserted it and checked out dmesg:

NB:  Don't expect to be able to recover data from the drive after this.
If the drive is fake, the test is going to overwrite data.

Description : F3 is a utility to test for fake flash drives and cards. It is a
: Free Software alternative to h2testw.  f3write will fill the
: unused part of a filesystem with files .fff with known
: content, and f3read will analyze the files to determine whether
: the contents are corrupted, as happens with fake flash.

A real drive should just get further filled up to capacity, fake drives
often wrap-around when filled up beyond their real capacity.

It boggles the mind how someone could go to the trouble of making fake
drives.  Is it just selling of failed builds?

Install package f3 and run the f3probe. 
Probable a fake flash. Bought an 8g flash that was too 
cheap. It comes up originally as 4 2T usb devices, but the 
f3probe calls it as fake, and reports it as 4 about 64G 
devices so it again looks nice, but is useless fake device. 
Facebook SCAMs that they keep pushing and getting 
bigger and bigger.
