 Posted: Tue Dec 10, 2013 1:34 am Post subject: Having issues getting my USB floppy drive working |
 |
|
I bought a USB floppy drive to transfer files from my modern computer to my vintage ones. I tried compiling the floppy driver in the kernel but that messed some things up. I've compiled the driver as a module instead but when I try to load it, it gives me an error:
| Code: | sudo modprobe floppy
Password:
modprobe: ERROR: could not insert 'floppy': No such device |
dmesg gives me this:

I have a USB floppy, yes these are strange beasts.
No, you don't need the floppy.ko driver - that's for the 8272 clones. These drives show up as a 1.44MB /dev/sdX drive like a hard disk and just use it as a hard drive, pretty much.
I don't know how you would format these things however. I think it's best to format floppies in a real floppy controller than one of these things. I also do not know how it would behave with 720K disks, I've only tested with 1.44MB standard high density PC format disks.

Is the USB floppy detected by the BIOS(EFI) as a bootable drive?
If yes, have you try to use it as a bootable drive to see how it work?
Have you try to make it work with an other Linux live-cd distribution?
It is easier to compile the Linux floppy support as a module if you need to pass it some parameters. Like eccerr0r said you dont need it, this module do not support USB according to it source code. But you may miss some USB support for your floppy.
You have the Linux floppy kernel parameter that can be use to change the kernel behavior. See /usr/src/linux/Documentation/blockdev/floppy.txt.
Have you try to make it work with an other Linux live-cd distribution?

Yes, it does show up as a bootable device in my BIOS.
I'll check to see if I can boot from it.
I currently don't have any live CDs or burnable CD/DVDs.
UPDATE:
It does not boot from the drive...however, the only bootable 3.5" floppy I have is DOS 3.30 for a Tandy 1000 HX.
One thing I do notice thought, about every two seconds, the light on the drive flashes.
Also, when I try to mount the floppy using:
| Code: | | sudo mount -t msdos /dev/sdg /mnt/floppy |
I get this error:
| Code: | | mount: /dev/sdg: can't read superblock |

It's because your floppy disk is not formated in msdosfs. You can execute the command
to know the filesystem in which the floppy disk is formated and/or try
| Code: | | sudo mount -t auto /dev/sdg /mnt/floppy |
You may need to format the floppy disk in a filesystem of your choice before mounting it. A dirty filesystem can be the cause of Input/output errors. Use the badblocks command to verify the integrity of the floppy disk. Change it for a new one supported by your floppy drive if the problem persist.

The behavior of my usb floppy when a disk is inserted is for the drive to first read it on its own - which makes sense in order to become a real SCSI mass storage device. I don't know what the behavior is if the disk can't actually be read however.
I'll need to do more experiments on this drive, and I still don't know if it's possible to format disks...
