Title: A600 Diskchange problem
Post by: tribz on April 16, 2011, 05:05:57 PM

I have an A600 which I've started using and it has a problem recognising a floppy disk change.

If its started with Workbench 2 in the drive, it can boot from it but doesnt notice a new disk after that.

What could be causing that?

There's a switch in the drive that is used to detect when a disk is changed. It could be stuck or dirty or broken.

In a Shell, and with a disk in the drive type:

diskchange DF0:

What model of disk drive is it?

Chinons usually have jumpers on the rear and early Panasonic have either switches/resistors.

Yes, its a Chinon. Tried the diskchange command but didnt work presumably because Workbench wasnt in DF0:

Will take the top of the floppy and see if I can see anything obvious.

Quite a few of the keys are also reversed when typing (q & a for example), presume thats just a keyboard layout or could it be a sign of a faulty keyboard?

Hi!
The command DiskChange stays in C directory in SYS: volume (Workbench in your case).
If you want to use it without diskette inside copy it to RAM:

From CLI/Shell:
copy c/diskchange to ram:
path ram: add

For the keyboard, if it's just 'Q' vs 'A' and maybe 'L' also, it should be just AZERTY layout (used in France, if not wrong).
Change keymap...

For the floppy check this thread (my hint - had a similar problem):

BY and let us know!
