Formatting a floppy - Help required.

2003-08-25 Thread Verghese George
I tried a simple command of formatting a floppy drive 
#fdformat /dev/fd0

It comes up with an output 

Errors encountered:

cyl Head Sect Error
0 0   1   no address mark in ID field
0 1   1   no address mark in ID field
1 0   1no address mark in ID field
1 1   1   no address mark in ID field

etc  

I tried the command
fdformat /dev/fd0.1440 
and fdformat -f 1440 /dev/fdo
but the result is the same.
Am  I doing something wrong?

I am using freebsd 5.1. I had no such problems when I was using version
4.0

Hello,

Usually any type of floppy error can be associated with a 'bad' floppy. If
you've ever taken a floppy apart you will quickly realize that the
magnetic surface of the floppy has the feel and consistency of tissue
paper.

As well the majority of floppies are treated, myself included, as throwing
stars or other dust to be introduced by how I treat it methods. 

If I were you I would try a new floppy and see if you can format then. You
as well might look into the /etc/disktab file close to the top for other
instructions on how to format a floppy.

NOTE: I have gotten error messages using FreeBSD/Linux/Tru64 and no
messages on a Win32 boxen on one floppy. Then trusting the Win32 I ended
up losing data later when it finally reported that the floppy was no good.

I hope this helps somewhat.

R.

PS

I have heard that manufactuers only warranty their floppies for 3 months
from time of manufacture. That and the relative slow transfer speed makes
you wonder why we haven't moved to other more sexy methods of booting up.

I too am having problems with formatting floppies in 5.1. Went thru a 
handful of floppies I regularly use and none worked. I don't have 
anything but FreeBSD on this machine for a 2nd opinion on the condition 
of its hardware but the same floppies formatted without error and seem 
to work in another machine with NT4.

On return from NT4 I was unable to write files without 100% low level 
errors to the floppies with mcopy but was able to read what the NT4 
machine wrote.

The last time this sort of thing happend I found an oddball BIOS setting 
put an end to the problem in FreeBSD where NT4 had no problems. Have 
not had that problem with this MB and RELENG_4.
