Personally I disable memory mapper in DSK-PRO. Otherwise it seems to freeze.

Quote:

Gentleman, DSK-PRO 11.6 works pretty well but it needs DOS2 or Nextor to work perfectly.
With DOS1 it works parcially just with unprotected disks.
So, boot with a mega mapper, or a megaflashrom or any other cartridge with DOS2 or Nextor.
Then start the file DSK-PRO.com
Let me know about the results.

Well let see what is the result

Ok now using DOS2 I run DSKPRO11.6 and I get a FILE.PDI but when I try to copy from a PDI file to a disk it always resets.
The PDI I've used is AQUARELA.PDI in drive A and an empty disk on B the file AQUARELA.PDI is 462336 Bytes
Let do some more tests.

Sorry but at the moment I can't
Anyway I did this time with DSK-pro 11.6 , a megaflashrom scc+ SD and tried to copy from the PDI file I has obtaines before to a disk with the native memory mapper 128Kb of my philips NMS 8255 and with a memory mapper with 4096 Kb , in both cases the program copied Track 00 sector 0000 sides 1 and 2 and then stopped.
Did the same test with DSK-PRO 11.1 and same results.Finally did it with DSK-Pro 10.2 and full success .
I think there is some thing wrong with the memory mappers and DSK-PRO 11.6 (and 11.1 by the way)

How can DSK-PRO dump PDI to a floppy disk? One saved to a floppy disk is only 710 KB long and lacks the part beyond B1600H. Is there any option that splits and saves to be later concatenated like DMK does?

As you can see if you read what @cbsfox told and what I wrote myself I used a megaflashrom scc+ SD with Nextor , This gives you much more than 713 Kbytes and I used DSK-PRO 10.2 with full success on AQUARELA.PDI which I wrote to a Disk and us fully operating. For the PDI files generated by PDT.EXE it's another story , for that you need for sure DSK-PRO 11.6 wich covers more pretections but does nor work fine with my Philips NMS 8255 128 KRAM and 128 KVRAM 2 drives.That is what I can tell at the moment.

When I try to dump with DSK-PRO to my Rookie Drive, if the mapper is enabled as default, DSK-PRO freezes upon an attempt to write. With mapper disabled by pushing D key, a PDI file is generated but is nonsense. On the other hand, I can make a DMK file by saving to a floppy disk, convert it to PDI by PDT then write it back to a floppy disk from Rookie Drive using DSK-PRO 11.6 with mapper disabled. My other environments are A1GT (unsupported FDC) and Sony HBD-F1 external drive with W.DIGITAL.FDC .

Well I tried again with dskpro 11.6 in megaflashrom scc+ SD
This time I desabled memory expansions , loaded the file PDT built , put Source drive B: Target Drive C: the file was read and saved to a disk
Once finished it worked 100%
So this time I can tell DSK-PRO works fine , Thanks to sdsnatcher73,Takamichi and mainly to cbsfox for his splendid tool

Of Course Thanks as well to tcm1998 for coding PDT.EXE without it the procedure is not complete
