Grex Micros Item 74: DiskCopy for the Mac?
Entered by raven on Fri Feb 4 22:20:47 UTC 1994:

Does anybody know anything about DiskCopy for the Mac? I just dowloaded a
file from Apples FTP site that reqires DiskCopy to to install the application
on a floppy. Is this application shareware? If so does anyone know an FTP
site that might have it?

20 responses total.

  Forgive the rather stupid response but... Isn't diskcopy when you
drag one disk over another and your Mac makes a perfect copy of
the disk you want to copy?
Or is it something else?


#2 of 20 by srw on Sat Feb 5 08:24:56 1994:

It's something else. You are describing the act of copying a disk.
DiskCopy is a program. I think it's an Apple program, so it's
not likely to be anywhere (unless its on ftp.apple.com).
I wish I had a definitive answer for you.

Definitive answer: I ftp'd DiskCopy from ftp.apple.com a little while
ago. Here is part of what Apple says about it:

"Although there is some similarity between disks duplicated from disk 
images and disks copied by dragging icons, the results are not 
identical. Floppy disks created from image files are exact duplicates,
including the exact icon placement, appearance of all windows, and the 
correct name of the disk. In addition, with disk images you have the 
added assurance that all the files have been duplicated correctly and
completely."

DiskCopy is in license limbo. Here is what they say about *that*:

"LEGAL NOTE - DiskCopy 4.2 cannot yet legally be licensed for 
redistribution.  Apple Computer, Inc. is working to create a license for
DiskCopy, but until that time, you may not legally redistribute it once 
you receive a copy from an authorized Apple source."

I take that to mean that you or I can ftp it from ftp.apple.com and
use it, but I can't give it to you! (??? who's looking ???).

I meant to add: apparently what you downloaded raven is an *Image* file.
That opens (with DiskCopy on your desktop) to create an exact disk copy.

Someone wrote an init called MountImage, which uses such "image" files
and mounts them as if they actually were floppies.
This init is buggy and causes crashes. Do not use it.
Instead use diskcopy and put the image on a real floppy.

Apple is doing some good and weird thing with licenses.
Good: They are letting a lot stuff be available for free.
      (ftp.apple.com and from dealers)
Weird: they are not letting any of it be distributed from the real
      Mac archives where everybody looks to get Mac programs, like
      mac.archive.umich.edu and all its mirrors, or sumex-aim.

        I got disk copy from ftp.apple.com. Thanks everyone. Only problem is
I was using to install a stylewriter ii driver to drive my stylewriter so
I can could print gray scale images. Turns out I can't do that because
I have a Mac Classic that doesn't support 32 bit QuickDraw. Oh we, c'est
la vie.


#7 of 20 by srw on Sun Feb 6 05:43:01 1994:

Yup. You lose there. No CQD* in the roms, and no CQD init has ever come from
Apple. You can always buy a Q605 for $900 - new, or look around
for a used LCII or MacII IIx IIcx IIci - they should all be cheaper yet.
Q605 is the best deal, though.

*CQD = Color QuickDraw, needed for 32 bit QuickDraw.

I found DiskDup+2.3 in maue: may be a little more flexible than DiskCopy,
but is shareware ($20). I'll stick with DiskCopy.


#9 of 20 by srw on Sun Feb 6 07:01:06 1994:

I think DiskDup is great for duplicating floppies. I've tried it, and
have no complaints about it, but I don't use it. I think you still need
DiskCopy to transfer image files to floppy.

 Sun Remarketing has LCIII's for $1095 including a basic monitor.
1-800-821-3221 for more info and catalog.


#11 of 20 by srw on Sun Feb 6 15:30:38 1994:

Yeah but if you're going to spend that much shouldn't you be buying
a new quadra 605?


#12 of 20 by rcurl on Sun Feb 6 19:58:06 1994:

Er..isn't $1095 a little steep to just do a disk copy?


#13 of 20 by srw on Mon Feb 7 01:02:38 1994:

Yes it is, but we are proposing a solution to his gray-scale printing
problem. The Apple grey-scale printing software is way cool.
You can produce impressive gray-scale half-tones on a mere 300dpi
printer by using it, but you need a Mac that can do color, not a
plus. (you don't need color though, just a Mac that *can* do color)

        Sigh I wish I could afford a new mac... Well maybe by the end of the
year.

When PowerPC's come out, Prices on older Macs will probably fall again.


#16 of 20 by mwarner on Thu Jan 9 17:32:23 1997:

I have a friend who is making the step from a IIe to a PowerPC.  She has
a mailing list on 5" disks.  Does she have any chance of getting the data
into the new computer? 


#17 of 20 by kentn on Thu Jan 9 18:26:24 1997:

Depends on what the data is and what operating system for the IIe it was
created under, but in general, yes, she has a chance.  A null modem cable can
be a GoodThing if the files are text (and she still has her IIe and a serial
card for it).  Some of the files on the IIe may be in file formats that are
incompatible (ie. binary) with other systems.  For these, a save to text from
the original program may be the best way.  Also, the Mac can read some types
of IIe program data files, if it has the right software.  I guess what we
really need to know is what program produced the mailing list and in what
format the list was saved.


#18 of 20 by n8nxf on Thu Jan 9 18:27:09 1997:

If she still has the IIe, sure.  Connect the Power PC to the IIe via
their respective serial ports.  You will need a null-modem cable /
adapter to do this.  Then do a file x-fer between the two systems.
I've also seen LOTS of 5 1/4" Apple drives at U of M's Property Dispo.
You may be able to plug one of those into a PowerPC.  Perhaps some
Power users here can tell you.  I'd guess you can get one of those
drives from PD for $10 of less.

(kentn slipped in.)


#20 of 20 by mwarner on Thu Jan 9 23:39:40 1997:

Thanks for the suggetions. She still has the old computer.  I'm not sure
wha software she is using but it should be able to send a text version, no
doubt.
