ST Recover, a new ST disk utility on Windows

Postby ChrisB » Wed Mar 21, 2012 4:56 pm

Hello

I announce a new tool I made:

ST Recover can read Atari ST floppy disks on a PC under Windows, including special formats as 800 or 900 KB and damaged or desynchronized disks, and produces standard .ST disk image files. Then the image files can be read in ST emulators as WinSTon or Steem.

The program is free and open source.
You will find it here:
https://strecover.codeplex.com/

[ EDIT: The new website is https://github.com/ChrisBertrandDotNet/ST-Recover ]

I hope that will be useful.

Chris

Hi and welcome to the forum. It's always nice to see new Atari-related software is being developed. Thanks for dropping by to let us know.
Mega"SST" 12, MegaSTE, STE: Desktopper case, IDE interface, UltraSatan (8GB + 512Mb) + HXC floppy emulator. Plus some STE's/STFM's

It's always a pleasure to share a tool I made for myself at first.

I was just unsure which section of the forum I can write this announce.
Maybe it would have been better in the Other emulators & tools section ?

Hi,

Nice tool! Will be great for emulator users!

Will this utility be able to beused with USB floppy drives? If so are there particular ones?

Is there a possibility that you are able to write these unusual formats back out to floppy so that they can be used on a ST?

USB floppy drives will be limited to the ordinary formats (360 and 720 kB), because of limitations of the USB interface. That is due to the special driver I use (See http://simonowen.com/fdrawcmd/ for more information).
You need an internal drive to be able to read particular formats (as 800 or 900 kB), or do display the surface analysis, or to recover problematic (damaged or desynchronized) sectors.

Technically, it would be possible, but that is not really the objective of this software. The aim is to recover old ST floppies only, without the need of an ST.

brilliant :)

trying a few that i couldn't previously image, and one has this rather geometric pattern - any ideas why ?

also, it's asked me to contact the author :)

so, hello :)

presumably this particular disk is too badly damaged to make an image ?

This pattern is due to what I call "desynchronized disks" in the manual (see https://strecover.codeplex.com/ or the manual in the Zip).
That is normal with many 10 sectors/track disks.
Did the disk be read completely and correctly at the end ?

spiny wrote:presumably this particular disk is too badly damaged to make an image ?

This is different. The fact there is no pattern indicates the sectors are weak. Anyway, a blue sectors is correctly read, at a price of more analysis.
It would be interesting to do a surface analysis of this disk, just to understand the nature of the problem.

EDIT:
The program says to contact the author, because it is possible to send me a debug info about the raw tracks. You have to check this option in the interface.

thanks for the info, yes, the first disk reads in Steem with no problems :)

the second disk is still imaging :D

but on that note, can I request a feature ?

at the moment the window doesn't resize to show all sectors, would it be possible to show the whole disk ?

Ok, thanks! Would you consider making that 'other' application? I would assume you are well versed in the subject! :D There are some utilities available, but the support is patchy with one app running under DOS another only working with XP.. etc.

One more request, and I guess it's a pretty big one...

Somewhere down the road, could you make a version that runs
under Linux? This is for those of us who abhor Windows... :)

Thanks!

Be aware that there is a time limit option, you should change it to a few hours if that disk is really important to you.
I hope your drive will survive that ! :lol:
I don't offer that kind of warranty. Ah ah!

spiny wrote:but on that note, can I request a feature ?

Yes, you can always request. ;)
That bug is a bit strange, I have to check that on different character resolution (120 dpi for example).
The strange thing is I already checked that. 8O

Oh yes, I can always consider new things. ;)
But that may take time, because I program this kind of little application on my spare time.
For example, a complete disk program with a graphical interface, well tested and reasonably debugged could need 2 weeks to be done, as a full-time job. That is a equivalent to a few months, on my spare time.
Anyway, I keep the idea in my mind. Maybe one day...

DarkLord wrote:Somewhere down the road, could you make a version that runs

Unfortunately, I don't know much about programming under Linux.
But enough to say that it would mean programming a complete new application from scratch. Even the low-level disk access is completely different.
So, we may encourage or persuade true Linux programmers to do that job.

Jokes apart, I am happy to see interest for this program.
It's rewarding to see it useful to people.

Thank you.
It's only a small contribution for the preservation of the history of our computers. :)

The most strange thing about these floppy disks is they work fine after 26 years !
Most of my cdroms are hardly readable after only 5 or 7 years.
The future of data preservation is a big question now.

It exists a lot of utilities to backup floppy, but this one display easily the mapping of sectors like an ST copier :D

I meet you to put your release in your A.F. Wiki if you have the time.

Great work !

another polite feature request :)

when the image is finished, can you change the message to say 'image written successfully' or something similar, instead of the 'image terminated', as that (to me anyway) implies it was cancelled, rather than completed.

thanks again for this, it's reading some floppies I thought were dead :)

So we have a so nice & polite forum. :)

Sure. I like requests, when they are easy to realise. Eh eh!
By the way, I suspect my program to not be really in english, but more in a mix of languages. ;) I'm looking for a courageous person who can correct my numerous errors of english.
Sorry, I learned english in the adventure games !

Nice! They were only dead alives until now. :)

Ok! I saw Spiny and Wongck create and modify the page :) and I saw that you register on the wiki today.

Now you can modify this personal page or another pages if you want.

And of course welcome on the AF Wiki 8)

Thanks a lot.
After a fight with the wiki codes, I wrote a small how-to in the above page.
Feel free to correct my English and add information if useful.

I suggest to correct the windows versions in the title, in the Disk Imaging page, since ST Recover is supposed to run under Windows 95,98,ME,2000,XP,Vista,7,8 and later (even if I only fully tested it under Vista).

Zorro 2 wrote:And of course welcome on the AF Wiki 8)

Thank you. :)


By the way, I don't remember if I fully tested my program with 11 sectors/track disks. [I wrote this application in 2010, and I can't access my ST right now]
If someone can test this kind of format and tell if it works fine, he would help me.

I'm interested in debug infos also, when sectors can't be read even after several tries.
If you check the option "Save track information debug" up in the interface, that produces raw track files that can help me.

Don't worry about the formatting, If you don't mind, I can format it for you.
You just type in the information.

I know it works for the rest of the Windows, but making an entry in Windows 7/8 makes it stands out :mrgreen:
Most of the tools fails on newer windows.
I will put an entry into the Win2K & WinXP section.
