How to write .image in FDD ?

[filipp76]

I want reinstall OS on my Classic II, I download System 7.0.1 from here, extract *.bin and have *.sea, after extract *.sea and have *.image, and now I want write this to FDD, but How ?? What utils (for Mac or Win or Linux) you use ??

In MacOS you use DiskCopy 4.2. In Windows or Linux Rawrite should do the trick. In Linux even DD would probably work fine.

DiskCopy not worked in Mac OS X 10.6 , rawrite after start crashing win

I don't know if it's possible in 10.6. I was thinking OS9 and below as DiskCopy 4.2 is a classic app. There's a windows version of Rawrite as well. Has worked fine for me for years.

Not working

I can't understand the error message. Why is your floppy drive B? It's usually A.

HFVExplorer can also write floppy images (File -> Write volume to floppy). Maybe you'd have better luck with that.

I try HFVExplorer, not working I have DiskTool.img his size 1474560 bytes and it perfectly write to floppy with rawwritewin-0.7, but images which I download from apple has 1474644 bytes ant it not writing Older I use util in which I set block size, and all works, but I dont remember her name

The size difference is the header information present on the old Disk Tools-style images. If you're using a tool like "dd" under Unix you can skip the header and write a usable disk using a command like:

dd if=(Mac disk image) of=(target device or floppy) bs=84 skip=1

In short, you have to skip the first 84 bytes of the image. If you have access to a Linux machine with a floppy drive, use the syntax in the linked article. You *could* use "dd" under OS X, but figuring out the name to the target device is a problem and I'm too lazy to tell you how to right now. (It may be on a Linux box with a USB rather than built-in floppy drive as well.) Alternatively, try a command like this:

dd if=(Source disk image) of=rawriteable.img bs=1 skip=84

Then try using rawrite.exe on the resulting file. (rawriteable.img)

I'm guessing you are unable to write these on your Classic II? That would be the best method.

I converted them to plain 1.4mb r/w images with DiskCopy 6.3.3 and they write fine in Rawrite (all images are now 1,474,560 bytes). You can get them here.

Another way to strip the header from the image in OS X is to use tail:

"tail -c+85 toobig.image >justright.image"

Thanks guys ! All work fine, both methods work
