  • Does none else has the same problem?

    Sometimes I´m creating a .d64, copying stuff into it by using a 1541 II on #9, with Fast Hackem, Action Replay Backup or Filecopy etc.

    After copying the stuff I´m going back to TC´s Main Menu, I answer "Disk Image(s) have changed" with "update" and then... my .d64 has no longer the correct 174848 Bytes! It´s getting bigger, the actual Test-Image has 183044 Bytes and can´t be mounted anymore, due "UNSUPPORTED D64 IMAGE SIZE"...!

    So some Disks are able to be copied, some aren´t, no matter how often I try.

  • i havent heard about problems with this for a long time... are you sure the filesystem isnt damaged somehow? please try to reproduce it on a freshly formatted sd card.

  • Okay, but I guess the missing update is not the problem.

    But I will update it.

    And I will try it with a fresh SD-Card.

    For more details: I created with F4 a new .d64, mounted it with C= and m, startet "Fast Hack'em", selected "Nibble two Drive Copy", copied the whole "Laser Basic Compiler" Disk from a 1541 II (Commodore DOS, JiffyDos bugs) on #9 to TC2 on #8, entered the TC2 Main Menu, agreed updating .d64, after then it's bigger before.

    Even with AR6 Backup or Filecopy I didn't succeed. *THIS* makes it even more strange to me.

    With this procedure I copied the most Stuff with success, except a few Disks like mentioned before.

  • except a few Disks like mentioned before.

    Some floppy speeders of the time allowed formatting 40 tracks. Popular names are "Speeddos+" and "DolphinDos", but you also find "S-Jiffydos" in references to using 40 tracks. These were able to format a disk to 749 blocks instead of 664 blocks by also using the higher tracks. If the disks you're trying to copy have been made on such a modified drive, you should be using a file copier instead of a whole-disk copier if you want to get your programs back to 170k-sized d64 images.
