No. Why? Because I actually know exactly how magnetic data recording, floppy disks, floppy disk controllers, floppy controller device drivers, and "dd" work. -Dave

Have you actually used dd for this and had it not work? Bob

[replying to my own email, man I must be tired] I neglected to insert a paragraph regarding on-disk physical formats. As I mentioned earlier, FM, MFM, and GCR encoding for bit representation.

...except what is meant by "1" or "0" when you're encoding bits in different types of flux transmissions? Are you aware of, for example, FM, MFM, and GCR? If what you're saying were true, there

No. Strictly speaking, you're correct, "dd" itself doesn't care about disk formats. However, the underlying device driver does, and the floppy disk controller chip underneath that does. The

"dd" doesn't care about disk formats.? It reads records sequentially and it writes records sequentially.? Unless they've put deliberate bad sectors on the disk, dd should work. Bob

There's virtually no chance of this working. This will only work if the disk is written in one of the few disk formats that are standard on PCs, which, as I understand it, the 4145A's is not.

The original, working, HP-labeled boot disk in my 4145A is *not* hard-sectored. -Dave -- Dave McGuire, AK4HZ New Kensington, PA

In my experience (from UNIX on), the dd command will copy anything except master diskettes which have a laser-shot hole in the medium for copy protection. ?Also slower (smaller chunks) seems more

"The "A" version uses a 5.25" diskette drive. The boot diskette is hard sector with a weird format that I've not been able to copy." I've renamed this to hopefully avoid threadjacking. If you have

Hi Wayne, I'd be really interested to know the process for the A unit if you've written something up. This seems like a great solution. Thanks! Matt

Hello, In what ways is the 4145B an upgrade from the 4145A? The B seems to sell for quite a bit more money. But, a quick look at the manual specifications seems to indicate they have similar
