Do you remember them ? 'course you do.

 

Anyway. I was checking some of my large stock of floppis and a few of them returned the error message 'No ID'. So they would not boot. couldn't even format them.

 

I suspect this is a throw back to the bad old days when viruses roamed the land.

 

Now, I do know that the disk ID lives on track zero and is in the first sector.

 

My scheme was to look at track zero on a  working floppy (with DEBUG or something similar), write it down and then fit it into the faulty disks.

 

Now the big question.

 

Does anyone know of any disk editor software that can access a floppy without needing to read the ID ?

 

Oh for the good old days of TSK ( the Tandy Survival Kit) which allowed one to do [bleep] near anything with the TRS- 80 disks.

You might try using Knoppix (LiveCD Linux) and access the raw device (/dev/floppy or something like that) and see if it can be read.

Are you sure its a problem with the floppy disc and not the actual drive?

Take a look here:

https://www.question...the-floppy-disk

 

Here the error code was similar but it was the drive that was the issue?

 

Have you tried all the usual "hex editor" and low level type stuff?

 

Dskprobe might do the trick..... its in the XP SP2 support pack tools...linky:

but you will need to scroll down a bit.

 

The media descriptor byte is " looked for" in XP and throws up the ID error, but Win 98 doesn't look for it, so this might be another avenue to explore.

 

I used Steve Gibson's Spinrite in the past for an automated fix ( or even would you believe) Norton Disc Doctor !  ...

any good?

Ps these trips down memory lane are making old paws feel...well old..!

I must pop up into the loft and drag out my old accoustic coupler.. as I reckon I could need to refresh myself on it shortly!

Kemasa, Paws,

 

Thanks for the hints.  I'm looking into them.

.

Kemasa,

 

Is that program on all Linux versions ?

 

Paws,

 

I think it is the disks as they show the same symptoms on another machine.

 

I have a more up to date query for you when I find the right section.

 

Dave.

Knoppix is a version of Linux that runs from a LiveCD/DVD. Any version would allow you to access the raw device. You can use programs such as cp, dd, etc.
