Amitek Fusion Manual Required

Peter · 24 March 2013, 12:12

Does anyone have a scan of the manual that came with the Amitek Fusion Genlock and maybe also the cut down SCALA Disk that come with it please...?

or... know where I could get it?

jimbob · 24 March 2013, 13:32

I have one of these in a box. Pretty sure there is a disk, might even be a manual. I'll dig it out later.

Peter · 24 March 2013, 17:34

Cool - Thanks!

jimbob · 26 March 2013, 22:35

Sorry Peter, no manual in my box and the disk is read error city

Most or maybe all files were recovered using disksalv salvage mode but with 10 errors. I will upload what I recovered if you want to have a go.

Should I try running disksalv multiple times or use the repair mode?

Peter · 26 March 2013, 23:13

Not to worry mate - I'll keep hunting - thanks for trying though.

prowler · 26 March 2013, 23:19

Hi Jimbob,

Please upload what you can of this disk image and I'll have a look to see if it can be fixed.

Please don't under any circumstances try to repair the original disk with DiskSalv, or any other disk fixing utility. You may render it irrepairable.

When I've had a look at what you've managed to salvage from the disk, I may ask you to send me the original disk for recovery if I think there's a good chance of success. I would, of course, return it to you afterwards.

zipper · 26 March 2013, 23:19

With bad corruption I remember I had sometimes to run disksalv 3 - 4 times until fixed. But it was a HD partition.

jimbob · 26 March 2013, 23:36

In the zone.
First attempt at adf with TSGUI, loads of read errors, some seemed to work with a few retries.
Scala folder has salvaged files.
Scala2 folder has a stream file from a second salvage attempt. (Not sure what this is exactly, I expected to also get the files after turning on the stream option?)

prowler · 26 March 2013, 23:53

Thanks, Jimbob.

That lot will give me a fair start. I'll begin by mapping the sectors to see what's missing. It may be possible to graft parts of the salvaged files including those in the DISKSALV-EXTRAS folder into the bad sectors of the disk image to repair some of the damage.

Depending on how much is recovered successfully, I'll decide whether it will be worth sending me the disk.

The only other useful thing you can do at this stage is to try salvaging the disk again a couple more times and also using other disk drives if you have any. In doing so you may be able to recover even more files and/or bad sectors.

Thanks again.

Peter · 27 March 2013, 00:25

Nice work guys!

jimbob · 27 March 2013, 01:17

Another set of salvage files in the zone. This time from an external floppy drive and only reported 3 errors.

I can actually boot the disk all the way to WB from this drive but it doesn't finish loading the program. Stops with a read error at disk block 1759 and then cannot open scala500.device.

prowler · 27 March 2013, 01:22

Great! Thanks again Jimbob!

I think I can say it will probably be worth your sending me this disk eventually. Three errors is not bad at all.

I'll do what I can with the data you've uploaded, but I would recommend that you don't send it until the end of this cold weather spell we're having at the moment.

jimbob · 27 March 2013, 01:34

OK, just let me know how/when/if you want it.

prowler · 27 March 2013, 22:03

Hey Jimbob,

Could you possibly have a go at producing another TSGui ADF image for me of the Scala500 disk using your external drive, please?

DiskSalv reporting only 3 errors on the disk when mounted in the external drive is a very good sign, since 10 errors were reported when using the internal drive.

The problem with TSGui, along with many other disk imaging utilities, is that when a bad sector is found, the entire cylinder containing it (i.e., the same track on both sides of the disk) will be missing from the disk image (i.e., zeroed out) - even if all the other 21 sectors are readable!

10 errors using that disk drive has resulted in the disk image you uploaded yesterday having Disk Blocks 264-285, 308-329 and 1650-1779 zeroed out! Also, Disk Blocks 1002-1044 are marked BAD (though I don't think this latter was caused by read errors).

This is far too much damage to fix manually, so I'd be grateful if you could give the disk another spin in your external drive and try capturing another ADF image using TSGui.

If you can get something even slightly better than before, that would be a real help. Thanks.

jimbob · 28 March 2013, 20:35

Another adf in the zone. This time done on the external drive using YADI with max retries on read errors. YADI reported sector checksum errors on tracks 151, 153, 155, 157 and 159. Could this indicate physical damage on one side of the disk?

Thanks, Jimbob!

Yes, it's quite possible that there is physical damage on one side of the disk causing those checksum errors. It could, for example, be a stain on one of the the recording surfaces caused by ingress of a small amount of liquid such as tea or coffee.

Those checksum errors are almost certainly the cause of Disk Blocks 1650-1759 being zeroed out in the original disk image you uploaded.

Please don't attempt to clean the disk, whatever you might find. I will see to that if necessary. There are ways of preserving the Disk Blocks which are intact before cleaning the disk surface, and I will do that if and when it's necessary to send the disk to me.

I'll report my findings regarding the latest image as soon as I can.

Hi Jimbob,

This capture is very much better than the original. There's a much more realistic chance of recovering it now.

The only remaining unreadable Disk Blocks are now 1670-1, 1688-93, 1705-15, 1732-7 and 1759. Disk Blocks 1002-44 are either not used or were overwritten by a virus at some point. I will find out when I have mapped all the sectors.

prowler · 02 April 2013, 00:25

I have mapped the first 1000 or so blocks of the disk image, so I should soon be able to tell whether it can be fixed or not.

@Jimbob: How did you produce the 'DS-Stream-File' file?

It seems to include all the important file names and data without block headers, so may be very useful indeed, although I haven't yet tried to figure out exactly how the information is arranged.

jimbob · 02 April 2013, 01:50

The stream file is created from the menu option archive stream after a salvage scan in disksalv. It is in the settings menu when you get the window to choose files to save and output path. I guess it is the raw bytes from the floppy interface with no attempt to interpret files. I think you might be able to load it into disksalv and try to save files from it?

That file was from a scan with lots of errors. I can try another one with the better drive if it is helpful.

prowler · 02 April 2013, 21:10

Good news. You won't have to send me the disk - I've fixed it!

It's in The Zone now.
