OS3.9 and old disks

[scuzzb494]

I am using an A4000d with an install of OS3.9 which I was not responsible for. When I insert an old version of a dd disk say like ProText for the A500 I am getting a DF0 not recognised. Yet I put it in my trusty A1200 with OS3.1 and it sees it no problem. I have noticed this to be the case on all my very old disks.

Any ideas why this is. I am not sure whether the 3.9 was the full install.

Faulty floppy drive?

Its very odd. Its the disk icon that is missing from the Workbench screen. Opening DOpus shows the disk.info. Asking the OS to show all items does not work. The way round it was to copy a disk.info from a blank disk and that sorts it. It is not the same with the blue tick style old disk icons just the black ones.

Most strange. And the disk is not a self booting disk.

Sadly looks like a floppy drive failure. Started with an old disk that I was using, not one of mine, and the metal slide was projecting. When I ejected it, it actually pulled the face plate off the 4000 drive. After that the drive has developed this occassional problem of not fully resetting itself after eject and seems to be locked in a state of wanting the old disk back. I wait a moment or so and then make sure I am firm with the next disk and has worked all afternoon.

The disk in question is very odd. I think its a bootleg or cracked disk of Tetris Pro and there is no visible disk icon, even though there is a disk info file on the disk.

I then tried an official copy of ProVector and that was throwing up the same issue and I simply took it across to the 1200 where the disk was seen and thought the machine was not seeing older disks. Turns out that the drive was stuck as described above.

Needs some work I guess.... surprised though that the OS cannot see the disk.info icon for this disk. It is completely invisible. Even after I copied it to a new disk.
