RISC OS 5.28 on PI3 - m sata drive dissapears

I have a pi3 in a Element 14 desktop pi box and it has a hat with a m-sata connector.
Externally this is connected to a USB port.

It worked on 5.27 but the drive icon vanishes from the desktop on 5.28.
I swapped back to 5.27 and it came back.

I have not explored this extensively yet I was wondering if anybody else had seen anything similar.

One of the Boot Configuarations is labelled Disc perhaps the drive is the relivent disc set to 0?

Did you upgrade by copying the new ROM image to the existing SD card, or did you swap SD cards?

On the Element 14 Desktop Pi box, swapping SD cards is a convoluted process: you have to remove everything from the case in order to get at the SD card slot. This raises the possibility of a mistake when reassembling the hardware.

I successfully performed an in-situ upgrade of a Pi 3B+ in an Element 14 Desktop Pi box (5.26 to 5.28) by running InSituBootUpdate and copying the new ROM image to !Boot.Loader on the SD card. Apart from an inconsequential software issue, everything went smoothly.

You have, I trust, checked *UNPLUG (might as well start with the bleedin’ obvious)?

I think that you can check this on 5.27 before doing the upgrade.

If the SDIO driver is unplugged on an early 5.27 then SCSIfiler will be unplugged on 5.28. ROM modules are unplugged by number (and there is an extra module in 5.28), so an unplugged SDIOdriver in 5.27 becomes an unplugged SCSIfiler in 5.28)

This is all from memory, so I may be talking rubbish! But, worth a try.

While still on 5.27 I checked if anything was unplugged and no, nothing was.

This was an in place upgrade in the Desktop pi box but since its such PITA the box has been discarded and the PCB stack just hangs about on my bench now.

I pondered the CMOS file as I did the upgrade. I would never have done a ROM upgrade on Acorn hardware without expecting to do power up R and reconfigure everting else. On 5.28 I get no keyboard present at boot so I doubt that would work and I wondered if there some other way to get the OS to write its defaults to the CMOS file.

Anyway I swapped back to 5.28 rebooted and the M-Sata drive was back. No idea why. I will keep it under observation.

Run Configure, then in its menu CMOS → Default.
