Entry 1510: Blog: 1

May sound odd but I rarely use the DF0 on my workhorse A1200. 
The machine has an external HD drive, ZIP, CD and SCSI hard 
drives so I have very little use for it.

I had a request for three ADF images of some very old 17 Bit 
Software PD disks and was firing up ADFBlitzer when the floppy 
drive appeared to fail. I say fail, cus in truth it may be 
performing as intended as this machine was acquired from 
someone else.

The A1200 is running OS3.9.

If I put a floppy in it throws up the usual Amiga floppy image 
and a PC image icon on the screen. The drive then locks the 
computer to that disk. So when I remove the floppy the drive 
does not eject the icons from the screen. Also, if I put in 
another floppy it will not be recognised.

The process ignores the reboot as when it fires back up both 
floppy images are still on the screen and you cannot load 
another floppy in the drive.

The external HD drive works without fault.

The workaround [ there always is a workaround with the Amiga ] 
is to wait for the boot screen and when you see the pause 
in the text as it attempts to load the Squirrel, I then 
insert the floppy I want to use, and like magic it becomes 
the floppy on the screen. This is of little use if you want 
to swap the disks.

The drive works without fault, because if I stick my 
Cannon Fodder disk in and boot it will recognise all 
DF0 disks and the swap overs for various disks. The machine 
just locks the first disk inserted when in the OS. And 
it even ignores a hard boot with the power off. The machine 
just locks the DF0 to the disk, whether it is there or not.

If I wasn't such an eternal Amiga optimist I would even 
suggest it could be a virus. My optimism suggests though 
its a hardware setting. I am not so pessimistic to think 
its hardware failure. That never happens [ fingers crossed 
as ever ]

Anyway disks have been sent out into the world so preserving 
some Amiga demos for future generations.
