Chad, are you planning on coming to the meeting tomorrow? If not,
Victor, maybe you are?

A USB drive is probably best for me, or otherwise an internal drive is
fine.

Trying to avoid having everyone turn up with floppy drives, or else we
really *will* be trying to do the Imperial March!

I had the same problem last week when I was having a clearout and 
discovered about 4 boxes of old 3 1/4 discs from my past.  It was at 
that point that I discovered that neither of my computer motherboards 
had connections for floppy disk drives. The latest doesn't even have IDE 
drive connections.  The floppy drive is still installed in the case, 
just not connected to anything. I COULD NOT get it to be read by linux!!


It seems to me that I should probably bin the old 3 1/4 drives in my 
store now.


Luckily my neighbour was cleaning up an XP box for a friend and I was 
able to recover the few bits that I wanted from these discs onto USB.

Re: [Dorset] Borrow a floppy disk drive

2014-07-30 Thread Ralph Corderoy
Hi Tim,

  If you have non-DOS-format floppies then USB probably won't be any
  good.  In their wisdom, they made the USB interface only support
  normal DOS formats;  no 1024-byte sectors, 10 sectors per track of
  ADFS, for example.
 
 One of them is labelled 'Minix' so might be ext or something, but the
 others will be DOS format. I wondered about external USB floppy
 drives, whether it's a standard thing or would need a special driver
 on Linux.

The defined USB Floppy Interface wire protocol is the limitation.
http://www.usb.org/developers/devclass_docs/usbmass-ufi10.pdf

Table 5 -- no sector interleave possible!
Table 35 -- Three formats supported:  DD,80T,2H,9S / HD,77T,2H,8S / 
HD,80T,2H,18S.
80 * 2 *  9 *  512 / 1024 =   720KiB
77 * 2 *  8 * 1024 / 1024 = 1,232KiB
80 * 2 * 18 *  512 / 1024 = 1,440KiB
Table 19 suggests sectors per track, for example, could be specified,
but I think it's more you can sense one of the three Table 35 formats
and then read 9, 8, or 18.

Not even a mention of whether sectors are numbered from zero or one
AFAICS.

Hang on to those real floppy drives, and a controller since it's a
partially analogue interface.

Cheers, Ralph.

I didn't get to Jelly unfortunately.  I have found the floppy drive and 
cable.  There are a few blank disks too which may be useful for testing 
it's installed OK before reading your disks.


I'll message you off list to sort out getting it to you.  :)

[Dorset] Borrow a floppy disk drive

Hello!

Does anyone have a floppy disk drive I could borrow? I finally get
around to investigating some old floppy disks of mine only to realise it
must have been years ago that I got rid of the last disk drive I had!

Thanks,

A USB floppy drive appears to the computer as a USB mass storage device, 
so IIRC the computer speaks something like SCSI-over-USB to it and 
accesses it as a block device. I think that's why they are limited to 
1.44 MB format, because there's no way to set the parameters over USB 
mass storage/SCSI commands?


It should appear as /dev/sdX, not /dev/fdX.
