Hi I’ve checked both my drives and how they’re connected and the settings in bios are correct according to how the drives are connected as far as I know and the 5.25 fdd size is set to 1.2 my floppy disk drive is a 1.2 size

Do You know the model of this FDD? You checked it is 1.2MB? Sorry if i'm boring, but this was my problem once (unable to format, read ok), when i didn't set right option in BIOS. 😀

Hi your not being boring I’m grateful for any help on this topic the brand of fdd is Tandon and the seller I brought it of on eBay
Says it’s a 1.2 model I’ve set it on 1.2 in bios but yes the brand of fdd is definitely Tandon T 75-8

Hi I downloaded the program I’ve tried following your instructions but when I press space bar it just makes a noise
I’m not Shure how to get to format disc option I have tried a few options and I just get a error message ive sent a picture of the error message I get

Heh? Seems to me you didn't even get into ImageDisk at all. The program has a red/blue screen similar to this:

You get into this by running IMD.COM. Once there, the rest of my steps should apply.

Hi I was wondering if you know of a YouTube video tutorial showing how to use imagedisk program as ive searched on YouTube and can’t find any I’m a bit unsure how to use the program if you know I’d be very grateful

Hi just a update on my problem with disks not formatting Ive found a nother floppy disk drive
That I have it’s a 1.2 and I’ve put it in to replace the other one that wasn’t formatting the new drive now formats my blank floppy’s I haven’t changed anything in the bios so that’s great I’m not Shure why the other drive didn’t format even thoe it read disks ok any way ive just noticed a message I get when I try to copy a disk with a program on it I type disk copy it say insert source disk which I do it copy’s info then it tells me to insert target disk witch I do then I get this message I’ve taken a picture of it the disk I’m using has 1.6 on it

Now the steps are from my muscle memory, so I might forget something:

1. Run IMD.COM
2. Dismiss the intro help text (press ESC)
3. Press space to modify options
4. Make sure Cylinders are 80 (1.2MB disks)
5. Set Sides to Two
6. Set Double-Step to False
7. Press ESC to leave the options
8. Navigate to Erase Disk and press Enter
9. Insert your disk in drive A and start the process

Erasing is going to blindly write a full-track single-sector on each cylinder. This will erase metadata in-between the standard IBM format sectors and the disk will basically become in "Unformatted" state.
I personally use this to revive disks which got "soft-damaged". I repeat the erase a few times. Once done, go back to DOS and try formatting again, and force the format using the /F parameter. Hopefully your Track 0 error will go.

Hi I’ve downloaded the imagedisk program on a 3 and a half disk I can only seem to run the program through windows 3.1
I’ve herd it’s better to run the program through dos mod do you know how I’d go about starting the program in dos mod from the 3 and a half disk

Make an DOS bootable floppy from windows format utility or boot from WIN 98SE repair floppy. As I remember, to install win 3.1 you need to have DOS installed, so you can just run IMD.COM from the 3.5" floppy (or other source you have IMD on).

Hi another update on the format problem I had yesterday after putting the new 5.25 drive in my disks
We’re formatting today I’ve tried formatting the same disks and new disks now I’m having exactly the
Same problem I had in the beginning my disks won’t format I’m getting the same error message I was getting in the beginning I noticed when I try and format in the disk image .com program the disks seem to format Alwright but not format the normal way also I’m not really sure of what settings to use in the disk image.com program to format properly not Shure what’s going on

Try formatting them in dos with the /U option.

To successfully force a change in density (eg, forcibly format a 1.2mb disk as 360k), you need to ignore previous format information. You do that with the Unconditional (/U) option. Otherwise, Format checks to see if the disk is formatted already (Y/N), then, if it is not formatted, just goes with what you have specified with the /F flag. If the disk WAS previously formatted, it checks the format type, and if it does not match your /F flag, it tells you that the density does not match.

So, basically, try this:

Format A: /F:360 /U

THEN, if it takes-- formatting back to 1.2mb:

format A: /F1.2 /U

H I’ve tried what you suggested when I type format a:/f:360/u it gives me an option to format in 360 kb and then doesn’t format when I try format a:/f1.2/u it gives me a error message I’ve taken a screenshot of error message for you to see

Try this:

1.2 MB
format a: /n:15 /t:80 /u

360 kB
format a: /n:9 /t:40 /u
-or-
format a: /4

I typoed when I gave the syntax. The colon is missing.

Should Be

format A: /F:1.2 /U

The options Disruptor posted will also work, and manually define the number of sectors and number of tracks, that are appropriate for the format.

Hi thanks for replying I typed a:/f:1.2/u this time it worked as it tells me to insert a disk but when I do it try’s to format but doesn’t and then gives a error message I’ve sent a screenshot I’ve tried multiple disks and still the same error message

Check the floppies for physical damage.

Can you run

1msd

and post a picture where we can see the floppy disk drive settings?

Hi I’ve checked the disks they were bought on eBay unopened as far as I know the media inside looks ok
But I’m not 100 percent sure I do know that the disks I’m having problems with I’ve used in a program
Called disk image.com as I was trying to format them that way as well but there’s so many different settings in that program
That I’m not Shure if I did it right

Hi I’m not sure what msd means and I’m not sure what you mean buy disk drive settings do you mean a screen shot of my bios

msd is "microsoft diagnostics"
it is a tool that is supplied within DOS and Windows 3.1x
you may run it from command prompt

Are you SURE these are 2-sided High Density disks?

'double density' is 360k
'High Density' is 1.2mb
