May or may not be available / practical to you but: I have one old machine still with a floppy and had that spin-up issue. The machine is an old HP and there is an option in the BIOS to 'hide (device) from OS'. The floppy was one of those 'device' options. 'Hiding' the floppy from the OS solved the problem. Of course, if I need the floppy I need to reboot and re-enable in the BIOS but that is not a frequent problem, to say the least.

I started doing that on several machines when in TW@13.2 I discovered this: https://bugzilla.opensuse.org/show_bug.cgi?id=916773 "unexpected fd0/floppy messages on tty[1-6]"

On windows however it works flawlessly. So there is a big in linux of course.

Now the floppy drive is detected as /dev/sdc could this be an indication of the problem?

Although when I use an el-cheapo external USB drive the drive works fine. (And is also /dev/sdc).

I notice that when booting up, the drive is fine in the BIOS and also in grub. As soon as the kernel is loaded the problem starts. Perhaps it is the floppy module not loaded or missing?

Yes there is an adapter on the back of the drive with a usb plugged into the m/b header. It is odd because an external USB drive works fine but using this adapter give me the same results as O/P The drive is ticking all the time with the LED flashing. I am worried this is going to wear the drive out. It is old after all. It is a Linux problem because when I boot to windows 7 the drive operated normally. In ubuntu or opensuse the drive is continuously being read all the time. The only way to stop it is to put in a floppy disk but this is not a solution to the problem. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org

Me neither, didn't even know they existed. over USB, yes, I knew, but never handled one.

I've worked with SCSI floppies back in the early 90's. Not on PCs though. I doubt seriously that the Linux kernel knows how to handle these devices properly. You say you have several machines doing this. Have you ever, on any Linux machine, actually been able to use these SCSI floppy drives?

unfortunately that did not work.

is there a possibility to create an udev rule, making udev not to try accessing?

I looked through this thread and I miss any prove that it is udev that continuously tries to access disk. There is log of single access attempt that could be interpreted as if access was caused by udev which is more or less normal - udev attempts to query SCSI device initially. Please upload full log after boot (journalctl -b) that shows *multiple* attempts to access drive, so that at least timing between them is known. I have my theory but I'd rather wait for facts.

This comes from kernel directly. It does it as the first step when probing for new SCSI disk. Note that if device explicitly says that medium is not present, "Spinning up" is skipped.

The above is executed only if driver thinks that medium is present (otherwise there is no point to even attempt to read capacity). Driver starts with assumption it is. Again - if device returns proper sense code indicating no medium is present, this step should have been skipped. Still, as READ CAPACITY fails we should have reset "medium present" indication ... ... and we announce block device sdc to user space (i.e. udevd) now. So udevd spawns handler thread.

Still kernel directly.

And *this* comes from udevd handler trying to open device node. Which triggers device revalidation. And apparently it also resets "medium not present" flag back because driver has never received proper response from device. And because driver flips this flag from TRUE to FALSE it apparently generates change event.

OK, this confirms that at the end it is kernel issue. You should really report it to kernel folks as true solution must be implemented in kernel driver.

OK, this confirms that at the end it is kernel issue. You should really report it to kernel folks as true solution must be implemented in kernel driver.

So there are two issues - (initial) spin up and permanent stream of "change" events. To workaround the latter - try disabling periodic device polling in kernel:

echo 0 > /sys/block/sdc/events_poll_msecs

Hello,

one little question: what is the concerned part of kernel? I did a bug general bug report on the kernel mailing list. But no response until now. Maybe I should mention the kernel module/part/whatever in the topic, and write a copy to the maintainer. But I do not have a clue which part it is.

Thank you again

Paul

both methods did not work, yet.. but I did not reboot yet.. I don't

Well, I expect this does not require reboot. Can you confirm that the value is still 0? -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org

Try stracing udevd

I know this is old but I had to use my floppy drive today to update a device firmware. I actually forgot about this issue. My workaround until now was to insert a broken floppy disk and it stopped the drive being polled.

I used to do firmware update from floppy, but found it's more often easier to setup a BIOS update by putting a FAT formatted DOS bootable HD in a USB device to load the update software onto, then boot the BIOS update target from the DOS HD. Some of my most used PCs that have floppy drives have a floppy hanging out to serve as a minimalist lift handle. If I encounter an errant floppy access attempt, I just shove it in until the issue is past.

I just tried: echo 0 > /sys/block/sdd/events_poll_msecs

as root and this workaround sorts out the problem until reboot.

udevadm monitor shows nothing before or after this command. by default /sys/block/sdd/events_poll_msecs is set to -1

This problem also exists on my dual boot of Ubuntu 18.04.1, on which the same workaround is working.

How can I make this workaround permanent?

Or has this been resolved and not released yet? Running on latest LEAP

I use floppies so rarely that I keep them disabled in BIOS except for any short periods they are actually needed. During installation, broken.modules=floppy is an option.

OK, this confirms that at the end it is kernel issue. You should really report it to kernel folks as true solution must be implemented in kernel driver.

So there are two issues - (initial) spin up and permanent stream of "change" events. To workaround the latter - try disabling periodic device polling in kernel:

echo 0 > /sys/block/sdc/events_poll_msecs

and check with "udevadm monitor" whether events stop.

For the former you can pass quirk parameter to scsi_mod; create /etc/modprobe.d/teac.conf (name is arbitrary) with:

options scsi_mod dev_flags=TEAC:FC-5:4096

Check /sys/block/sdc/device/{vendor,model} for correct values. This flag suppresses initial spin up of device. You will need to reboot (and do not forget you also need to recreate initrd as scsi_mod is most likely loaded there).

You can create udev rule, you can create start-up script that runs on boot ...

Or has this been resolved and not released yet?

You mean you did not bother to report it in almost 2 years?

Not necessarily that old, depending on your definition of "old". New PCs and motherboards at least as recently as 2009 were still shipping with ISA bus floppy controllers. Examples:

I tend to think "old" once they're less than SFr100 on ebay/ricardo.

I have the last, with 3.5" floppy, though a SFF model in which a standard 5.25" floppy drive could not physically fit.

I would make dd copies of those whilst you can - floppy disks don't last.

That's my intention. These are good quality disks, not the filth they sold on later days.

I thought dd copied sectors, regardless of the format. You should still be able to back up the disks and restore to another floppy.

As long as you use the standar number of tracks and sectors, not a proprietary format that reprograms the timings and the checksums sizes, payload sizes, etc. Floppy drives are very dumb, the processor has to switch the motors on an off "manually" timing the operations. Very different from modern media. Also means that the processor can not order the operation and forget, but instead keeps busy. - -- Cheers, Carlos E. R.

My desktop machine has a floppy drive, I installed it just in case I want to inspect and retrieve some data from old floppies I have.

I still have some old backups made in floppies which I wish to retrieve one day.

I would make dd copies of those whilst you can - floppy disks don't last.

That's my intention.

These are good quality disks, not the filth they sold on later days. I tried a decade ago and they were good.

dd is no good with them, they have to be restored with proprietary software (PC tools backup) in a suitable machine. Which is why it is such a nuisance that I balkout at the idea.

Which is correct, you don't have a /floppy/. you have something on SCSSI. There must be some other driver. - -- Cheers Carlos E. R.
