Emu-Emulator 1 disc dump shows up empty

Post by brian_ronn » Wed Jul 26, 2017 7:35 pm

Hi Wizards

I wonder if you will be able to help me decode what is wrong with these invalid Emulator 1 discs.

At the moment I have 181 disc sides at my disposal and I've used the Kryoflux disc controller on all the discs.

I used the standard Emu sector image on all the discs.

Only 72 disc sides came out as valid Emulator 1 discs and the remaining 109 disc sides shows up as empty Emulator 1 discs in Emxp. The valid E1 disc dumps always have the file size 123 kb but the invalid dumps ends up on 140 kb.

The owner of the discs tells me that all 181 discs sides have been written on the same E1 with the same floppydrive and that all discs worked before shipping them to me.

Ive also tried the none gui interface with this string: dtc -fEmul.emufd -i10, but with the same invalid result.

Here is the disc dump log file of one of the invalid discs sides:

Code: Select all

DTC.exe -l15 -fD:\Kalimba A.img -i10 -d0 -e83 -dd0

Might this problem be some kind of missallignment between my pc floppy drive and the disc owners E1 floppy drive? I wonder since 109 invalid discs sides out of 181 discs sides are a considerable number of discs errors.

What might be done besides changing disc drive if it is a missallignment?

Best regards

Brian

Brian,

I fixed the formatting of your post for you.

It's hard to tell from just the logs, but yes, alignment might be an issue. Also, you seem to have quite some USB errors. Any hub attached?

Hi Vince

Thank you for attending my issue and for the formatting of the log :-)

No usb hub is attached in between the kryoflux and the pc. The pc usb port is a slow 1.1 version though. Might that be a cause of the usb errors/error rate? Should I attempt with a usb card v.2.0 instead?

Trying to locate another 5.25" floppy drive could maybe correct any misallignment or do the opposite so I would like to fix any other issues first.

Best regards

Brian

No need to change the USB port if you can live with the retries. It's right at the edge of what the port can deliver, and maybe it's an internal bridge, where other devices are connected (keyboard) as well.

Hi

Well, I've now changed the usb port to a version 2.0 pci card and used another connector on the floppy cable which is closer to the Kryoflux controller but the end result is still the same.

I think too that this matter is about drive alignment but I'm very hesitant buying a new drive just to hope for a matching alignment on the remaining discs. I think the chances of a matching alingment are way to small.

I would have expected that none of the discs would have worked or almost all of them since the discs are from the same system. But the discs are from different manufacturer so I guess that the brand of the discs have a different degrading over time.

Best regards

Brian

I wouldn't give up hope yet... could you post one of the bad disks as stream files?
