I've had old floppies seize up, or have trouble rotating, using a pen or
something to insert into the offset hole near the center of the floppy
so you can spin it a few times might work. You can also try snapping the
housing open, freeing up the floppy, then closing it again, sometimes
that works. If the floppy is already considered dead or unusable you
have nothing to lose.


You should open the 3.5" floppy shutter anyway, for a quick look.

Just to see if there is obvious degradation.

Another possibility, is the OP is mixing incompatible things.

The Wikipedia article on floppies, shows a ton of options
from other platforms. Just because it looks like a floppy...
it might not be meant for your PC. I'm sure if I shoved one
of my Mac software floppies into a PC, I'd see some "sad panda"
symptoms for my effort :-)

Some BIOS have some sort of "Japanese" setting for the floppy,
but my failing memory doesn't recollect the right techie
term for this. I think that setting may cause the
floppy drive to fail.

If you're going to be an "anthropologist" with computers,
you're going to need a ton of research. And perhaps from
an era where not a lot of breadcrumbs are left.

When you said you could 'see some files' do you mean the were displayed
in the File Explorer?
What do you mean 'could not activate' them. What programs exactly, and
do you know if they are 32 bit or 16 bit?
Can you copy the images to the XP or w7 hdd and view them from there?

That's the test. Make a temp folder and verify you can copy the files
off the floppy to the temp folder. If that goes well and you wish to
keep the files save them onto something newer such as dvd or/and )better
to do both) backup hard disk ... may be only/last chance

Interesting experiences and comments. So, I'll add mine.

A few months ago, I had a lady that needed some tutoring in using her
Mac laptop. When we were done, as part of the conversation, she said
she had some floppies from years ago that had some photos she would like
to retrieve. But, no one was able to read them.

I brought them home. Yep, I couldn't read them with any Windows
computer I tried. And, on some, I had to use my USB external drive. No go.

Kept getting a message that said the floppy could not be read.

Tried at least one of my Macs, no go. I don't remember if I tried the
Mac that actually has a built in floppy.

I think I tried my Linux computer, but I don't remember.

I have an Atari clone, tried that. It read every stinking file on all
of the floppies! Burned those files to a CD, and she was a happy camper.

Moral? Don't depend on mainstream systems to always work.

If you read the Wikipedia article on floppy, you'll
find there are plenty of variants. Interworking is
not a property of them.

In some cases, it's actually media differences. The magnetic properties
aren't the same (from the various eras). The same thing happened
with optical drives and media. Original CD drives could not read CD-RW
media, because nobody imagined the existence of such at the time. A
different laser power was required. Laser diodes now, have a power
control (for writing purposes), so the laser is kinda "fully programmable".
The lasers on the first CDs were likely just too weak on output
to stand a chance.

The CD, DVD, and BD, use different wavelengths. And different
optics too (not the same lens setup). But back in the CD era,
the wavelength needed was probably the same, but the laser
was just too weak. So in its own way, optical media is the
same. They aren't all "optical discs" - each one is a
pretty unique standard, and your drive is trying those
standards one at a time (different laser, on a carousel),
in an attempt to read the media tag. Like, a BD drive might
have three lasers.

With floppies, there were 360K, 720K, 1440K, and some Japanese
standard which might have been a higher value (and perhaps a different
drive). I have some motherboards, that they came out of the box,
set for the Japanese standard, and needed to be set to something
I owned. (That wasn't the LS-120 either, as the LS-120 is
an IDE device and doesn't use the floppy controller chip.)

You can be lulled into a false sense of security, by dipping
into that same box of PC floppies for the last 15 years, and
simply assuming they're all the same. I was a bit shocked
reading the Wikipedia article, because I'd forgotten about
some of those other platforms I'd never owned, which happened to
use a different drive.

The problem was almost certainly with a missing media descriptor byte.
Read he
https://support.microsoft.com/en-us/...ognized-by-win

And ignore the terrible solution they propose there. The best solution
is to format some diskettes on a modern Windows computer, then take
those newly-formatted diskettes and the ones you want to read to an
old computer running Windows 95 (if you can find one) then copy the
diskettes to the newly-formatted diskettes there. Those copies will
then be readable on a modern computer.

I don't think it was so much the _power_, as the _colour_; CD-Rs (and
RWs) have a decided colour cast, whereas stamped CDs (mostly!) don't.
(The writable ones probably _do_ need a bit more power to read them too
- certainly if the laser colour isn't optimised for them.)

There's also the format: you can write CD-RWs and CD-Rs in different
formats from CDs. (Even if you used the right format, unless you wrote
it all at once, the reading drive had to have "multisession" firmware,
otherwise it would either only read the files written in the first
session, or none at all.)

And Microsoft's own one that got _slightly_ more than 1.44 on a floppy
(I don't _think_ it was "the Japanese one" [was that 2.88?]; it was only
about 10% more, IIRR). I _think_ they used it just so that the number of
floppies needed to hold Windows 95 - which could be bought on floppies -
was reduced slightly. (The first at least floppy in the set was at
standard 1.44, and included software to control the drive to get the bit
more.) (Oh, it probably made copying more difficult, too, which they'd
want.)

some of those other platforms I'd never owned, which happened to

My Oric Atmos - and one of the early Amstrad word-processors (a complete
machine, not a piece of software) - used 3" drives, not 3.5". (A more
solid structure, IMO - didn't catch on though.)

Konica Technology, Inc., 777 North Pastoria Ave., Sunnyvale,
CA 94086-2918, 408/773-9551, ships KT-510 10-megabyte floppy drive in
volume.
Downwardly compatible with ordinary 360Kb and 1.2Mb drives (Z-News
607-4),
half-height 5.25" drive has embedded SCSI controller, 1.6 megabits per
second
data transfer rate, and 75 milliseconds average access time.
Diskettes--480
tracks per inch, embedded servo written--produced and sold by Konica,
for from
$10 to $25 depending on quantity, are conventionally jacketed, not
cased and
shuttered as are Kodak 10Mb units (Z-News 801-4). Such diskette prices
will
certainly come down if they are ever produced in high volume. Such
volume
depends on a major computer manufacturer using them in their products.
These high-capacity floppy drives, from either Kodak or Konica,
especial-
ly with the SCSI interface offer much easier and faster backup to RAM
and hard
disks than do tape drives. Random access, instead of sequential, to
stored
data make the difference. Make direct contact if you are interested in
using
one in your personal computer.

I know they were available for Atari and Amiga systems, I don't know
about any other systems.


I never really understood what that setting was for, but it's
mentioned in the last paragraph in this floppy article. The number
3 refers to modes, not density. Who knew?

https://en.wikipedia.org/wiki/Floppy-disk_controller

"3mode" floppy drive

I thought it might have referred to a higher recording
density mode (because of the way the BIOS was worded),
but it just appears that some floppy drive supported
three different densities. That must mean the floppy
controller in the SuperI/O, was ready to deal with
three different looking patterns coming in from the
read head.

*******

That Konica thing isn't the highest density achieved,
as the LS-120 and LS-240 went higher than that. And
appeared to be floppy-media based, but with optical marks
for servo purposes (so a higher track pitch could be used).

In North America, people would have been more likely to
use ZIP drives. I have a ZIP250 here for example, for
interworking with work media. Mine was USB based, but
they made a flavor with parallel port interface as well.
That would be competitive with an LS-240. The cartridges
for the ZIP250 were pretty expensive.

Also, disk compression claimed a doubling of capacity, but except in
very unusual circumstances was more like 1.2 times than 2.
