..how do I format a floppy so that the Quadra will recognize it? and what are the symptoms of a bad floppy drive? It will move the head up and down the disk once, and then eject it with the flashing X on the floppy symbol...
ps. I did find a version of the Apple SC HD setup that is patched (7.5.3) and is in .app format, i think...
The disk copy operation will copy the floppy's format to the disk. Once you get a system onto that SCSI HD, then you can format a floppy on the Quadra.
The drive in the Quadra seems to be behaving as it should. It looks for a format (possibly doesn't find one) then would next look for a system to boot from. It doesn't. So it ejects the disk. Sounds normal to me but that doesn't mean the drive is ok.
dd if=[Source disk image] of=[NEW IMAGE.img] bs=84 skip=1
dd if=[Source disk image] of=/dev/[FLOPPY DISKn] bs=84 skip=1
What is the difference between the two commands?
The first command takes the original disk image and writes a new file with the first 84 bytes removed. Apparently, this should then give you a disk image that dd can write to a physical floppy disk.
The [Source disk image] is path to your original "Disk Tools.image" file (including the file name).
For example, if it was on your desktop, then it would be:
You must always preceed a space character with a backslash. Hence the:
The second, skips the intermediate task of writing the new disk image as a file, and instead writes the disk image with the first 84bytes skipped onto a physical floppy disk.
[FLOPPY DISKn] is where your floppy drive is. It may be something like:
depending on how many physical drives (hard disk, thumb drives etc) you have. Look in MacOS X's Disk Utility. Select the floppy device (not the volume on the device) and click on the Info button. The "Disk Identifier :" is what you're looking for.
that you only need the 'bs=84 skip=1' when the SOURCE disk image is an original DiskCopy 4.2 disk image. You will only need to strip those first 84 bytes off ONCE.
...where is the "patched" version of disk tools? Is it the two formatters listed on the website?
Yes, HD SC Setup 3.01 (A/UX) is linked but he's pasted the raw text of the file into the page. I've attached that file as a .hqx
