[ECOS] floppy access in cygwin

[ECOS] floppy access in cygwin

[A Roturier]

hi,

this question was posted and asnwered awhile back. but i can't
seems to have it resolved still.

i try to copy the pre-built image of redboot for pc platform
onto floppy disc in order to boot from drive a:.

in cygwin,

$ mount
C:\cygwin\bin on /usr/bin type user (textmode)
C:\cygwin\lib on /usr/lib type user (textmode)
c:\cygwin\tmp on /tmp type user (binmode)
C:\cygwin on / type user (textmode)
\\.\a: on /dev/fd0 type user (binmode)
c: on /c type user (textmode)

so floppy drive is mounted correctly.

$ dd conv=sync if=redboot.bin of=/dev/fd0
dd: /dev/fd0: No such file or directory

this command takes about 8 seconds to execute before error
message is printed. and the light of floppy drive is on for
a while. i have checked the floppy and media and they work
fine in windows.

any idea? thanks for help.

kc

I know it seems obvious, but is the floppy write protected? Also you should
probably try to do a low level format of it first from within Windows. If
this works let me know and I'll update the docs. If it doesn't, the next
port of call is probably the cygwin@cygwin.com list.

Also make sure that there isn't an Explorer window open with A:\ and that 
there is no console session that has A:\ as its current directory, 
otherwise you can't get an exclusive lock on the drive.

Sometimes volumes seem to be owned by phantom processes in NT (2000 
especially), and can't be reformatted until you reboot.

hi,

i had formatted the disc and copied a few files onto it to make
sure the floppy was ok before i issued "dd" command. and i m
certain there's no other process occupying the floppy drive.
btw, i am using windosw me and might it be the origin of the
problem? :p

anyway, i'll try cygwin list. thanx Jonathan and Lewin!
