I am having problems with RISC OS 5 v5.28 on Raspberry pi.

For some unknown reason to me the time and date keeps referring back to
2/1/1970 it has done this for months.

After several attempts to change the time and date I now get the
"FileCore in use" error, the system will not boot up properly and it
still shows the same incorrect date.

It is also showing "Filing system or path HostFS: not present" which
means I cannot load anything from the HardDisc like !Configure in order
to change settings as it reports "FileCore in use"

Another error on start up is/was Share not found, not sure if that is
related to anything here though.

No idea whats going on but is there a simple way to change or fix this?

Which model of Raspberry Pi?

Does your Pi have a RTC (Real Time Clock) ? If so it might be needing a
new battery.

Is this on an SD Card or are you using an SSD or HardDrive as well?

If SD Card only when did you last back it up? SD card don't last forever.

It could be your SD Card is failing. Have you tried runing DiscKnight
(even the trial version will check the SD Card\disc I believe).

You might have a file or App on your desktop pointing to an external
device/drive that is not connected

Ensure you have backup's......

Its a Raspberry Pi4 on the Fourtress

Not sure, I think it gets the time from the server when booting.

Its an SDHC card

Sadly I have not backed up the SDcard.

I have DiscKnight but can't get it to recognise the SDcard as its not
ADFS.

Andy from RISCOSbits is helping me with a new SDcard which should solve
the problem.

DiscKnight v1.55 (current version) will read the SD Card on SDFS

I have DiscKnight V1.55 and just so I can try checking the SDcard what

showing HostFS::DriveD.$ but what Drive number will it be as nothing I

Are you on the Pi or on an emulator? HostFS is an emulator thing. Did you
copy things from an emulator to the Pi perhaps?

HardDisc Details section:
Enter SDFS in the "Filing system" field and probably the "Drive number"
will probably be 0

Remember to only do a "Check" of the disc (SD Card)

I've tried that thanks but shows error
"DiscKnight 1.55 (12-Aug-2018)[32bit] *CHECK ONLY*"

Arguments: -v -m -l -t -s SDFS 0
Unable to determine SWI call for filing system SDFS

I'll wait for the new SDcard to arrive, albeit that wont help resolve
not being able to read from DiscKnight so it must be something I am
doing wrong here as I can't even read my VA laptop HostFS::HardDrive4
with DiscKnight never mind an SDcard.

I am on a Pi 4 specifically the Fourtress with Ro5, I haven't copied any
files from the SDcard.

HostFS::DriveD.$ is what DrivePop shows when the mini SDcard is in the
ScanDisk adapter.

I'll wait to receive the new SDcard then all should work again on the
Ro5 side, just puzzled why I can't read the SDcard with DiscKnight.

DiscKnight only works on Filecore formatted filesystems (ADFS, IDEFS,
SCSIFS, SDFS, etc). Emulators (mostly*) don't use Filecore FSes, so
DiscKnight won't work on them.

Wait until you get your new SD card and then try running DiscKnight on the
Fourtress, pointing it at your old SD in the USB adapter (probably
SCSIFS::something). Don't use VA for this because it will just confuse the
issue.

Theo

* If you can pass through a whole-disc image as an ADFS drive in VA, then
you might persuade DiscKnight to work on it. But most of the times
emulators use HostFS which relies on Windows/etc to store the files for you.
Windows stores them with FAT, NTFS, exFAT formatting, etc, not Filecore.

What is DrivePop? What matters is what filer icons are on the iconbar.

From your other later post, it sounds as if DiscKnight can't find SDFS. I'm
not exactly sure how the Fourtress is set up, but I think it's using non-SD
hardware for its main storage (the RISCOSbits website refers to m.2 NVMe or
SATA). If this is the case, then the SD card may not actually be used from
the RISC OS side: it will just be used for booting the system and faking the
CMOS.

As such, the SD card may not even be visible from the RISC OS side as a
Filecore disc at all (and there may not even be a Filecore partition on it),
so SDFS may not be relevant (or even enabled?).

Looks to me like Stephen may be taking the SD card out of the FOURtress and
putting it into his Virtual Acorn machine to run DiscKnight on it. Which
would explain why SDFS isn't present, and HostFS is.

Err DrivePop is a program supplied with Virtual Acorn, it might or might
not work on a Pi 4. It should not really be needed on a Pi.

Are trying to read the SD Card on a Pi or a Virtual Acorn install on
another computer?

Not surprised you can't read it on your VA as i don't think DiscKnight can
read HostFS drives as they are not real drives. VA uses the underlying
Windows drive.

Again if I wait for the new SDcard from Andy I won't have to bother with
DiscKnight.

It is all a bit beyond me I'm afraid, but thank you all for the help.

DrivePop is a HostFS pop up drive manager, I use it on RISC OS 4.

I have played about with this and did manage to get DiscKnight loaded
and working to a point on the dodgy SDcard on RISC OS 5 but the card is
flaky at the moment so can't check properly.

Think your right here, I cant view it on RISC OS 4.

I have not tried to see if DricePop works on the PI4 as the PI4
automagically shows pen drives when loaded and I've no idea what it's
called.

Yes I was tring to read it on the VA machine with RO4.

DiscKnight wont help with "FileCore in use" errors, as it's not a
problem with the disc, but a software error probably caused by trying to
load newer filing system modules.

>>>>>> It is also showing "Filing system or path HostFS: not present" which

There is no HostFS on the Raspberry Pi, it's only found on emulators.

It sounds to me like you have copied a disc image from an emulator on to
your SD card, so it is failing to boot causing the date to be wrong and
the filing system modules to be screwed up.

That wont work, DiscKnight can only read disks directly on machines
which run RISC OS natively, not on emulators.

It can read disk images when running on anything, but that wont help here.
