Part of it is:  Greater data density was achieved through use of finer
magnetic particles.  Those inherently are more likely to demagnetise
neighbouring particles over time, the price of higher density.  E.g.,
you will probably find that your 720 kB 3.5" floppies, if you have any,
have lasted better than the 1.44 MB ones.

Ironically, floppies made longer ago seem to last longer.
Floppies (mostly 3.5") seem to have been made more cheaply / lest robust.

Coupla years ago I went through all my 5.25" Atari disks (from 1986 thru
let's say 1998), and only _one_ failed to read.  (It worked at first,
but failed later, when I actually went to copy stuff.  RIP, little bits.)

Thanks for the reply. But never mind, it works with some diskettes but
not others. Evidently some floppies do not last 27 years... who knew. :)

I was able to use a floppy drive on Ubuntu 14 last year. Don't know if that
helps.

Any thoughts? I've tried 2 different drives, 2 cables, and 3 diskettes.
I'm pretty sure the cable positioning is right.

[vox-tech] Floppy drive with Linux Mint LMDE 2 MATE

[Rod Roark]

Wondering if anyone has any experience/insight with this. I have some
old (1989-91-ish) 3.5" floppy disks that I want to archive the data
from, and a TEAC 1.44 MB drive (actually 2 of them).  The PC is a
homebrew with a Gigabyte H55-USB3 mainboard and older Intel i3 CPU. The
floppy interface is enabled in BIOS settings.

As you may have guessed it's not working. With either "mdir" or "mount
/dev/fd0 /mnt/floppy" the drive LED comes on for a few seconds and then
a message indicating /dev/fd0 does not exist (not true), and this
reported from dmesg:

> [  138.845258] floppy0: probe failed...
> [  139.243808] floppy0: probe failed...
> etc...
> [  144.821238] blk_update_request: I/O error, dev fd0, sector 0
> [  144.821245] floppy: error -5 while reading block 0

/dev includes this:

  brw-rw 1 root disk2,   0 Aug  2 12:22 fd0

Any thoughts? I've tried 2 different drives, 2 cables, and 3 diskettes.
I'm pretty sure the cable positioning is right.
