A1020 5.25 Mountlist entry for workbench 1.3

[PlatformerZ]

The mountlist you've written is correct compared to the WB 1.3 mountlist in SYS:Devs other than that specifies DF2: rather than DF1: as you have. 40 tracks would be 440k I assume.
    Something I didn't know was, until reading online, the A1020 doesn't support diskchange detection so when removing a disk and inserting another you need to type in CLI "DiskChange DF2:" after changing disks.

 Another point shown online is REMOVE DF1: could be needed first if DF1: is auto-mounted at boot for a 880k drive?

Over the past 8 years I've had half a dozen floppy drives fail for no rational reason. Some were seeking tracks without any signal from the Amiga, others failed to read consistently giving bad sectors or not reading at all - ndos. It's quite a phenomenon in these times that the modus operandum of tech is a slightly more diverse demographic on a permissive timeline. I get quite emotionally bogged with the constant need to service the floppy drives; caused by a shift it said tech status in the location.

I can only recommend investing your energy into the drive by way of cleaning the heads with a bud tip and isopropyl alcohol and even lubricate the rails with some oil or silicon/graphite. If all else fails; bringing a floppy drive up to speed with the modern matrix may involve a head alignment.
