Manx Data drive

I have a Manx Data SD drive which has for some time been happily attached to the USB2 port of my Rpi4 running RISC OS. But now, when I click on its iconbar icon the system responds with “has this drive been formatted?”. I think it was formatted to FAT32. If plug it into my Rpi5 running RaspberryPiOS I get a crash – the screen goes blank. Back on the RISC OS machine, Discknight will check it and tells me to run a repair. When I do that it throws up its hands and says contact the author. So what can be done now, apart from junking it?

If it is not a FileCore format, DO NOT run DiscKnight on it!

DiscKnight does not understand any other format such as FAT32, and will try to turn anything it repairs in to a FileCore disc, which is unlikely to make things any better.

!Fat32FS comes with a utility to check/repair FAT32 formatted disks. It worked with some of my drives but not with the 2TB one (I formatted it with another tool provided with !FatFS32 and I think it made the partition 1 sector larger than the disc size).

However as an attempt to repair it with DiscKnight was made, it may have already been too late.

If you have run DiscKnight and followed the instructions which say to create an undo file during the repair, you can return the disc to the state it was in before. Do that before using any FAT32 recovery program.
