How many people have had problems using .IMG files (NDIF images) to transfer files from OS9 to OSX?


I've lost some important data because some of my .IMG files are apparently now missing their resource forks.  I didn't realize that files in OS9 were PHYSICALLY SPLIT into two parts on the actual disk. Of course, the very idea of doing such a thing is beyond absurd. Yet, i never had any problems transferring files in the past, even when using e.g. PC-formatted Zip disks, because both parts of the file were always there! The error when i try to mount the images now in OSX is:


The following disk images failed to mount

[filename] not recognized


Nor can i take the files back to my OS9 machine and mount them anymore, to my horror.

    Hi again, I think you didn't keep the old copies on OS9, where they'd still open as always.


    Also, did you use a FAT32 formatted Flash drive maybe to tranfer them?


    The thing you could've done is used Stuffit to Stuff them before transfer.


    Despite your lawyer, I doubt a suit has any merit.

    Yes, i probably used a Windows-formatted USB drive to transfer the files. Could have been FAt32.


    The problem is, when you see a file (icon) e.g. on your Mac OS9 hard drive, and you copy it to a USB (flash) drive, and it shows up there, and then you open it from there (to make sure it copied okay), and it appears fine, the idea of there being an associated *invisible* file is totally inconceivable. It's insane that anyone would write a computer operating system that places *crucial* parts of a single file IN ANOTHER, *INVISIBLE* FILE. Yet, that seems to be what's going on here.


    So, you copy that file (apparently) off to your other computer (OSX machine in this case), and assume everything is fine. Then some months later, you try to open (or mount) that file, on your OSX machine, and it doesn't work.


    Is this data (in the .IMG) recoverable..? The .IMG image is of course an image file containing lots and lots of other, smaller files.

    Do you still have the original img file in OS9?

    No. That appears to be the problem. I was using the .IMG files to *transfer* my files from my old OS9 machine to my newer OSX machine. Or at least, i *thought* that's what i was doing.

    If it opened from the FAT-formatted flash drive on your OS 9 computer, the "flattened" file is probably still o.k. You might try googling or something similar for applications which open .img and .dmg files. See if you can find an app that will open it. Stuffit Expander for OS X might work for example.  Do you have access to another OS 9 computer as well? (Even one that just works with Classic under an older version of OS X?)

    Huh, Apple edited my original post and removed words like "criminally" and "negligent" (as in, a file system that stores part of your files in separate, invisible pieces might be criminally negligent.... That's almost an oxymoron, isn't it, in that each "file" is really *two* files....


    Anyway, I do not have the files on the flash drive anymore. I do however have access to another OS9 machine, and the .IMG files don't open there anymore either (when copied back from my OSX machine). I'll try to get ahold of Stuffit X, but i don't see how that could do anything when the Mac's own software can't mount or open them. From what i've read on the web, these are proprietary image formats.

    You need the original OS9 ones, the ones tranfered via FAT32 are incomplete, no use trying to open the ones on/in OS9 that were on the Flash drive ever.
