Hi all,

Trying my luck with an Amiga issue on this C= echo.

I'm having issues with formatting (nevermind writing to or reading from) floppies on my 1200.

I've basically stiffed the internal drive. Now, trying to format a floppy in my external drive...I get a consistent "Couldn't format Cylinder 0" error. The floppies in question were very well cared for and previously working fine - and it is happening across all of them.

I'm worried I have somehow fried the drive logic on the motherboard, as I was previously having the same issue on the internal drive (leading to my ill-fated repair attempts.)

Any ideas or suggestions much appreciated!

Hi, it seems like a High Density - Low-Density problem.
Try covering the little window on the right with some tape.


Ciao.

The floppies are double-density ones I'm afraid. So no holes to cover.

I did make me think though, as the external drive I have is a Power
Computing one that supports HD as well as DD. But fiddling with the mode
switch at the back doesn't seem to help.

I cleaned the heads yesterday and managed to get one side of the disk to
give all greens on xcopy's checkdisk function - but the others were
completely red. And still not formatting - with the "Cylinder 0" error.
