Can I repair my NDOS floppy disk using the image file created by WHDLoad's RawDIC?

[A4000_Mad]

Hi Guys,

I picked up this Amiga game at a charity shop for 50p



So I got the installer from www.whdload.de and all went well when I put the game into an A4000 with the game running perfectly



But when I went to put it into another Amiga I got the report:-

Checksum error on track 159

I clicked 'Retry' many times with no luck, so I eventually clicked on 'Cancel' and was told"-

Disc imaging was not successful! RawDIC was unable to create all needed files!  

Is it somehow possible to overwrite the floppy using the perfectly good image of Disk1 created by RawDIC in my first successful installation of the game please?  

Thanks,
:pint:

Wouldn't it just be easier to copy the disk1 image file over to the 2nd machine?

Yes, that's quite true thanks Piru But I would still like to repair my disk as I don't like having faulty ones

maybe the floppy drive on your other Amiga is at fault, since it works on your A4000

I thought of that thanks loinstorm and tried again with the same A4000 and same floppy drive. The disk has definately become faulty. I would never normally insert or remove a disk while the floppy drive light is on. But unfortunately this is one of those rare games where the floppy drive read light stays on all the time. I had no choice but to remove Disk 1 to insert Disk 2 while the floppy drive light was still on. This probably caused the checksum error.

Anyway, does anyone know if the image of Disk1 created by RawDIC can be written to a floppy with some kind of program?

Thanks guys,

I'll look for an ADF or another complete, boxed copy of the game

However, I now consider it an Amiga challenge to write that image of Disk1 to a floppy disk. Does anyone know whether it can or can't be done? :confused:

WoW! That's all great and helpful stuff thanks spirantho :drink:

If the corrupt track is on an AmigaDOS track (there may or may not be any on XJ220), then just use a simple imager to write the correct track

What simple imager would that be? :confused:

Your best bet is to get hold of a disk copier like Cyclone, or X-Copy Pro or something, and just copy the disk using your A4000 which can read it fine. If it were just the disk that were bad, the 4000 wouldn't read it. If copying the disk works, you could copy the disk to another disk, and then copy that copy back to the original again. The alignment will now be with your A4000 drive rather than the disk duplicator that originally made it.

Unfortunately the A4000 only read the disk fine the first time and can't read it again now


I've got this copying gadget.............





Would this give me a repaired disk or just another copy of the faulty disk?

Isn't that the one that needs special hardware? I think X-Copy Pro was the best one which didn't need a dongle. I could be wrong though.

If the A4000 can't read it now, then you won't be able to copy it - you'll need to find out what's supposed to be on that track!

Note that RawDIC doesn't image the whole disc, it skips the copy protection tracks completely as it doesn't need it (WHDLoad removes the check), so if the dead track is the protection track I'm afraid you can't do anything at all....

Your best bet would be to find out what the WHDload imager does, maybe the person who wrote it can help?

Hmmm... Looks like this Amiga battle could be lost unless the WHDLoad guys can be of help.


Yes, the Synchro Express does have the special hardware dongle which you plug onto your external floppy drive port and then plug on the drive itself

Thanks again spirantho

I've had luck inspecting floppy disk surfaces through the little window and finding spots of whatever on the disks and removing the spots gently with a cotton swap dipped in rubbing alcohol.  I'd say it's a last resort, though.

That's worth a try thanks tone007
