I can only say that I successfully copied my old CP/M disks to .d71-images with this tool. Did never try the other way around. Can you post the .d71 here or by PM? I can try to copy to real 1571 disk and test on my system.

I had no problem creating a real 1571-disk from the cpm30zexall.d71-image on my C128/1571-combo. I could then boot from the newly created disk and start zexall.com from CP/M. However I noticed I had a newer version of DiscCopier on my SD-card. I don't know if this means anything, but here's the newer version:

I am going to try that disk copier tomorrow! I have been trying to find a reliable way to make double sided CPM disks from .d71 files for weeks!

The DiskCopier program worked just great. I copied the CPM 3.0 .D71 file over to my SD2IEC, copied the DiskCopier.prg over to a standard 1571 disk (First to SD2IEC, then the prg file to a disk - then I had to strip the .prg extension from the file).
I used Dracopy to browse to the folder that my .D71 were on on the SD2IEC and quit the program so the C128 used that location as the active file location. I launched DiskCopier, chose the option to copy .D71 to 1571, chose which drives I was copying from and to, and waited 20 minutes for it to copy. Boom! Perfect double sided CP/M disk that worked perfect. Now... To figure out how to use CP/M. I will play with this some more and do a video on it withing the next week or two.

After you become extremely bored with the standard CP/M, try this flavor of CP/M instead : csdb.dk/release/?id=171699Have fun playing rogue.com =) Set up 80 column display, 1581 drive, and 16MB "REU" ram expansion unit .. in emulator beforehand. Z64K emu makes it easy : csdb.dk/release/index.php?id=172120Cheers! |

Thank you! I downloaded the program and works well  Doesn't matter if fast or slow, but it do the job in a great way, right what I was looking for. Thanks again Tony |

I know this may be a few years too late, but I've been working on several programs for replicating disks using a parallel modified 1541 drive. I had an idea for replicating double sided 1571 disks from d71 images by writing the first side from a d64 and the 2nd side from a g64 that has been bit-reversed. I haven't tested this approach yet, but if there's any interest, I will get to work on this.

For regular cpm disks that would be needlessly complex
The ‘ctools’ will read files from the d71 file and write them to a set of d64 files
This will (of course) not work if the files are larger than 1 side, unless you change the Bios to use 2 1541s as 1 drive.
Also, remember a d71 has 1 bootsector that would not be replicated to the 2nd d64
Cpm places the dirblocks at diskstart so the 2nd d64 can only work in a 2nd drive at the same time
Then, cpm only uses block-io so the physical layout is actually irrelevant (if you read the d71 per block and place that block on a d64, no need to bitreverse)
For MFM (like on g71 image) this of course fails too.
Still interesting to know if you can create a 1571 cbm GCR disk from a d71 on a 1541 (or 1570 …)
Or vice versa, reading flux from a 1571 doubleside disk to create a d71 (which could be of use)
