Hi experts!
-----
It will difficult to explain my problem without giving command lines !
I've got a f*ck!ng message saying "Sorry, you are not allowed to post external links. "
WTFIT?!?
So I've deleted all my code quotations ! >:(

My problem :
I try to read a 1.72MB MS-DOS floppy from USB drive.
My release of TC is:
uname -a
Linux box 2.6.33.3-tinycore #2012 SMP Wed May 12 17:05:42
The USB drive is detected under dev sdc:
I fail to use existing fd0H1722 device.
I added a line for fd0H1722 but it doesn't help...
What am i doing wrong ???
Do I have to create a special device with "mknod" ? How ?
Could you help me please ?
Best regards,
Disket.

Not sure what to do if you see a need to quote code while being prevented by spam control, perhaps a moderator could advice...
As you already suspected yourself, you need 1 device node per each floppy format.
A MAKEFLOPPIES script is included in www.tux.org/pub/knaff/fdutils/fdutils-5.5.tar.gz
I wouldn't know if it script still works, as it is slightly dated (2002); also I wouldn't be familiar wrt any particularities of USB floppy drives.

Upon checking, I found that /dev/fd0H1722 should exist by default in tiny core 2.x & 4.x, so couldn't exclude that your issue *might* be specific to USB.

I am not an expert, but you can confirm that if you have an external floppy drive it does support 1770 kB according to your maker's specifications?
As I just did a quick google and the only hits I was getting was for 1440 kB floppy external drives
and maybe I am stupid but I thought /dev/fd0H1722 was for internal floppy drives?

I'm pretty sure /dev/fd* applies only to devices connected to the floppy controller.
... I found that /dev/fd0H1722 should exist by default in tiny core ...
I found that too, but my machines have floppy drives. I don't know if those device nodes get created if a floppy drive
is not attached.

At least in 4.x they are included in the cpio archive ;)

Hi Disket
Try:
sudo mount -t vfat /dev/sdc /mnt/sdcThen:
ls -l /mnt/sdcand see whether the directory listing is normal or garbled.
-
In case your drive is formatted as msdos or vfat fs, you could try to follow this guide:
http://www.arahne.si/support/faq/127-usb-floppy.html
after first having installed the mtools extension; assigning a "drive letter" to /dev/sdc while setting
cylinders=82 heads=2 sectors=21
However, also note:
Please note that reading or writing of floppies on USB floppy drive in nonstandard formats, like Stäubli JC3 or Stäubli JC4 is still not possible. You need a normal floppy drive for this.

In my experience, situation: normal. This isn't a TC-specific issue. USB floppies are commonly connected as SCSI devices as the USB chips in the drive speak USB mass storage just like a USB flash drive or USB hard drive. There is no magic device node to create. You need a real floppy drive on a real floppy controller or a USB floppy drive capable of handling the 1720kiB format (of which I know of none and I doubt such a device exists).
