Couldnt format cylinder 0

[bbond007]

I have installed an HD floppy drive (FB-374A, Amiga HD floppy) in my 4000T and went and bought a brand new box of HD floppies preformatted as 1.44 PC disks.

I can format an 800K floppy no problem and is recognized as an 800K floppy. Put in an HD floppy and is recognized as a 1.76MB floppy, click format, then the DF0: icon on the desktop changes to busy. Then after a few seconds I get the error "COULDNT FORMAT CYLINDER 0"

I have tried 5 different disks with the same results.

Anyone know whats wrong?

Thanks!

I used to have the same problem but I quit using floppy disks. whdload, and now HXC floppy.

You may need to cover the notch so the disk appears to be a 800K.

I also used to have that track 0 issue with my A1200 when trying to format pre-formated PC 1.44 formatted floppies.

What I used to do was first write a DMS(game/demo/etc.) to the disk then for some reason I was able to reformat it afterwards without getting the cyl 0 error.

I think it also might help if you had a magnetic bulk eraser.

I hereby award you an Amiga.org Floppy Disk Science Achievement Award for 2013, March 09.

Commodore floppy drives are obviously powered by voodoo side-effect, so any given advice may or may not work Its a little like giving advice on curing the hiccups...

Like I was also able to format a new 1.44 to 720 on my PC then somehow it would magically work as an 880K on my A1200 without thetting the cyl 0 error.

Will it format disk as 1.44mb PC floppy?

On the Amiga (with HD floppy) the 1.44 MB floppy should format to 1.76 MB unless its got some damaged areas.
