[cbm4linux-users] Cant open source from d71

[Mats J. <mj...@ti...>]

Hi.
I have started played around with my 1571 in 1571 mode(doubleside mode).

When i use d64copy to create a d71 image it works very well the image is
created and works well.

But then when i should write a d71 image to the drive i only get the erro=
r

d64copy  -2 image.d71  9

[Fatal] neither a .d64 not .d71 file: hej2.d71
[Fatal] can't open source


Anyone know?

/Mats

Can you tell how big the image is (in bytes)?

This message tells us that the d64copy thinks that it is neither a D64
nor a D71 image (what else should this message tell?), and this is
determined by the size of the image in libd64copy/fs.c - open_disk().

BTW: Have you tried without specifying -2? From a brief view, it does
not seem to have any effect on this message, but to be sure... (D71
always use 2 sides, so there is no need for specfying it).

Regards,
   Spiro.

Can you tell how big the image is (in bytes)?


349696 bytes

This message tells us that the d64copy thinks that it is neither a D64
nor a D71 image (what else should this message tell?), and this is
determined by the size of the image in libd64copy/fs.c - open_disk().

Ok.

Yeah the same error occurs.

Good.

There's a silly bug in the above function. This should fix it:

I wish there was a knob on the TV to turn up the intelligence.
There's a knob called "brightness", but it doesn't seem to work.

Well, this is the correct size for a D71 image.

Ok, another try: Can you send me the image via PM? Please compress it
before sending.
