Changed Roms from Cloanto 3.X to 3.1 Can Only See Partitions with Emergency Disk HELP

There's an exec interrupt bug in v45.061 that breaks floppy drive operation.  It's fixed in v45.064 which should be available very soon if not already.

Your ROMs should be under warranty, so arrange to return them to your vendor and I'd expect they should be able to re-write/replace them at no cost.

Interesting. Source?

I work with the software developer doing the recent ROM development work for Cloanto, specifically I was doing some hardware compatibility testing on v45.064.  Not sure how publicised this bug causing intermittent floppy operation is, but it's been around a bit over a year and observed by a number of users.

And Cloanto now list v45.064 as the current version, they also state that the floppy interrupt problem is fixed in this version.

Updated 2016-10-05, nice!

I have the ROM 3.X in an A600 (with ACA620) and can't remember any floppy drive problems, so either I'm lucky or A600 systems aren't affected at all.
