SystemDisk does not work anymore on RO5.27

I changed from Risc Os 5.24 to Risc Os 5.27 (Risc Os Direct download version)
And now !SystemDisc hangs as soon as i enter the drive number. No error message. But complete system hangs. Mouse pointer is the only thing still active. But nothing else. Only solution is power off. Going back to Risc Os 5.24 it works as usual.
(Hardware is Raspberry Pi 3)

Is that a known issue, or what is the solution for this?

I also found, if im using Spark FS on RO 5.27, after unpacking on RO 5.24 or another RO5.27, file type get lost. All files are of type data afterwards.

I believe that it’s this known issue.

That sounds similar to a known problem with SparkFS 1.44 (although in that case files ended up with load/exec addresses of 0000/0000 instead of a filetype). The fix there was to upgrade SparkFS – there’s a link on David Pilling’s site (look for “SparkFS upgrade to 1.45”)

Going back to Risc Os 5.24 it works as usual.

That’s the only solution I’ve found.

I keep a spare card with 5.24 on it just for this.

Can’t get CloneDisc to work even with 5.24 – it just gives up part way through!

And had same problem with Fat32Format the other day insisting a tiny stick had too large a cluster size.

And now !SystemDisc hangs as soon as i enter the drive number.

You can use an older SCSIFS by softload (doubleclick) or Colins scsisoftusbd3 (Floppy) driver. Both fixing the problem (and with CloneDisc) on Ti and Pi.
