Or perhaps just a buggy copier that worked at the MFM level for some reason.

trackdisk.device on a real Amiga can handle these incorrectly written disks, but the disk reads a lot slower than a disk with intact sector headers.

@chip, It's never going to be finished, TMB is sourcing disks from all over europe.
You might be better off asking when the world ends
@dlfsilver you know the channel to ask the right questions in.

Newly dumped disks are pure gold, everyone remember that, because without the hard work of some Amiga lovers, you'd have nothing.

But if you are doing a raw dump then these incorrectly written sectors should also be dumped. Then a little tweaking may be able to get them working?

As far as I recall, if someone was to KF/SC dump a disk, it cannot be written back directly (or at least that's what someone with the hardware has told me) without some further adjustments. Maybe this is what dlfrsilver could shed more light/help on?

Yes, naturally the exact contents of the disk gets dumped into the raw file, broken sector headers and all. Then dtc (the tool that comes with kryoflux) refuses to decode the broken sectors, but gets the working ones. All the data is still in the raw.

To understand why it is like this, KF/dtc come from a software preservation standpoint. It could be a copy protection, it might be a broken disk, but it doesn't second guess. It only accepts correct data.

Then a little tweaking may be able to get them working?

Precisely. The file format for the raw file is available + you can also mfm decode with the HxC tool and I think KeirF's disk utils as well.

True. While you can just write back a raw stream, there is no guarantee that your copy will work if this is done. The ipfs that everyone loves to hate are built from raw dumps, but actually contain information accurate enough for a successful remaster.

got an A600, will know if it is working in about a week, when it will arrive.
wished i had a nice fastram expansion like the A6095 so i could use samba, well cant have everything at once.

expect the problem disks to be transfered soon and also other new disk images popping up in this collection soon (many more disks to come!)

[chip]

Good to know ..... thanks !

[tmb]

so, after some time, I am back with a few images for you guys.

I noticed some .raw files inside the collection

When do you need this kind of format .... originals ?

yes, i use .raw for supposed originals and sometimes for disks which would need nibble-copy

I would prefer you dont do that, there are many on EAB forbidden files inside.
please don't mirror my uploads, thank you.

[Retroplay]

No problem, files removed.

Should have known there might be some WB disks.
Who would have thought this still would be an issue in this day and age.
Anyway, thanks again, much appreciated.
