 Posted: Fri Nov 15, 2002 3:28 am Post subject: I borked /dev/fd0 :( |
 |
|
I did a | Code: | | dd of=floppy.image if=/dev/fd0 bs=1024 |
I got the out and in files mixed up  (Shouldn't be logged in as root after 1 am  )
When I now run | Code: | | dd of=/dev/fd0 if=floppy.image bs=1024 |
I get the following error
| Code: | dd: writing `/dev/fd0': No space left on device
5+0 records in
4+0 records out |
I know my floppy drive can handle disks larger than 5kb
Anyone have any ideas about how to fix this mess?

first try mounting /dev/fd0 with a valid floppy. I never tried this command before for floppy, only for cd to make iso...maybe this command grab everything from floppy and can't write things like hardware vendor id or I don't know what else... Have you ever done this before? I am a pure newbie with floppy on linux, but noone seems to want to help you :'(

The debian boot floppies are created this way...
I've created floppies this way before so it should work. 
Trying again I get
| Code: | #dd if=fdlinux-v2-1-0.img of=/dev/fd0
0+0 records in
0+0 records out
|
I think what has happend is that I have broken my devfs somehow |

Moved from Newbies to OTG at request of poster. Is /dev/fd0 still a link to /dev/floppy/0? /dev/floppy/0 should be major number 2, minor number 0 if you want to try mknod.

/dev/floppy has the correct major and minor numbers
| Code: | ls -l /dev/floppy/0
brw-rw---- 1 hetr9922 floppy 2, 0 Jan 1 1970 /dev/floppy/0 |

I'm not sure
| Code: | ls -l /dev/fd0
lr-xr-xr-x 1 root root 8 Nov 15 23:51 /dev/fd0 -> floppy/0 |
Should that be /dev/fd0 -> /dev/floppy/0 instead? If so should I symlink or hardlink /dev/fd0 to /dev/floppy/0? |

Either way: it doesn't matter - that link looks OK to me.

Are you sure you didn't just b0rk your floppy.image - file with running dd wrong the first time??? Try mounting a floppy and see if you can use it properly, also check out the properties of your floppy.image. If I'm guessing correctly the contents of your floppy has been written into it...
Edit: The last time u tried it you didn't enter your blocksize (bs=1024), that's why no blocks were written (I think  ) |

I did. I forgot to mention that I downloaded the image again.

I don't have loopback support in my kernel I guess I'll have to fix that next time I recompile |
