    I would recommend taking all other podules out and connecting the drives
    one at a time to the motherboard interface to check that they work. Once
    you know which drives still working, you can put them back on the
    desired interface.

    Make sure you set the links on each drive to master when it is the only
    drive, and one as master and one as slave when 2 drives are on the
    cable. Do not use the CS cable select option, only grief lies here.

    Just thought if the master drive of a pair has failed, then the working
    slave drive might not be recognised either.

    I suspect this disc is not configured as a boot disc. The other 3.5 inch
    disc now prevents the PSU from starting. It seems to have failed during
    all the plugging and unplugging I've been doing.

    To make the disc bootable, you need to issue a

    *OPT 4 2

    Assuming it is set to the only disc on the motherboard interface.

    I would like to get this to boot again, probable using the 3.5 inch disc
    that does still seem to work. It holds a backup of a lot of what was on
    the failed 2.5 inch disc. Options would be either to connect it to the motherboard or the unipod. The latter requires *configure filesystem idefs
    I believe.

    *Configure FileSystem ADFS

    When using the motherboard.

    How can I get to the supervisor to reconfigure things? I don't have an RPC ketyboard now, only USB. The USB keyboard does get a reaction once I'm at
    the "failed boot" screen - pressing escape is equivalent to cancel. F12
    does nothing however.

    You either need to press shift when powering up or pressing reset, but
    this probably wont work if you have a USB keyboard via a podule. In that
    case keep hammering Escape from the moment anything appears on the screen.

    You should be able to get out of the failed boot to the desktop by
    pressing one of the buttons in the error box - can't check right now.

    Secondly, in order to make sure the 2.5 inch disc has failed, is there any way to connect it to an ARMX6? It's IDE.

    There are IDE to SATA adaptors, but the good old motherboard interface
    should you first port of call.

    I have an RPC I use occasionally because of some software that won't work
    on later machines. It runs 4.02.

    It has/had two 3.5 inch discs connected to the two IDE ports of a unipod,
    and one 2.5inch IDE disc connected via an adapter to the motherboard IDE
    port.

    I *think* the latter is configured as the boot disc. Recently I plugged
    this disc into the adapter incorrectly, only connecting the bottom row of
    pins of the dics to the top row on the socket. Since then, even correctly plugged in, it doesn't work.

    I've tried plugging the ide cable from the motherboard into one of the 3.5
    inch discs. During boot up, I get the ADFS message, and the disc activity
    light comes on, flickers briefly, then goes off. The boot eventually fails
    ansd offers "floppy boot", there's no floppy drive that works, retry,
    which gets to the same pioint, and cancel, which stops at the splash
    screen.

    I've checked the CMOS. Years ago I replaced the motherboard battery, and relocated it well clear on extension wires. It's still producing 1.3
    volts.

    Secondly, in order to make sure the 2.5 inch disc has failed, is there any
    way to connect it to an ARMX6? It's IDE.

    I would recommend taking all other podules out and connecting the drives
    one at a time to the motherboard interface to check that they work. Once
    you know which drives still working, you can put them back on the
    desired interface.

    Thanks.

    Done that. Only one causes the drive activity light to do anything.

    Make sure you set the links on each drive to master when it is the only drive, and one as master and one as slave when 2 drives are on the
    cable. Do not use the CS cable select option, only grief lies here.

    They were all masters - one on the motherboard, one each on the two Unipod interfaces.

    True, but not relevant here.

    I tried that. I'll need to try again (and again...)

    I thought that, but none do. The most likely candidate was cancel, which produced a splach screen in what I think is 800x600 resolution, then
    freezes.

    Making progress.

    I have found an old RO4 boot disc that still works. Connecting this to the motherboard allows the computer to boot. Connecting the remaining working
    disc, holding the data backup, to the IDEFS interface on the unipod also
    works. So I now have access to the data.

    However: These are both old discs. What I would like to do now is get the
    data onto a SATA disc connected via a SATA-USB adapter. Is this possible
    using a Unipod USB interface. If so, how would I go about it? (The disc is currently NT formatted, so I guess that would need to change).

    As an alternative I also have a Castle USB podule (4-port). Would
    connecting via this be any better?

    Only if the disc was smaller than 2GB [1] and FAT formatted. I don't think
    any such discs exist.

    (It is possible a disc with a single <2GB sized FAT partition at the
    beginning might work, but I doubt it)

    You could try a CompactFlash card in an IDE adaptor - if you want to
    transfer to another OS maybe FAT32FS would work with it? Otherwise you
    could format it ADFS. Note that some CF cards work and some don't. Some (CJE?) can supply ones that are pre-tested. I think they can also supply SD-IDE adaptors that might work.

    As an alternative I also have a Castle USB podule (4-port). Would
    connecting via this be any better?

    The card was a bit of a dead end, but I vaguely recall someone getting the
    SCSI stack on that to talk to large(r) USB mass storage devices than the
    Simtec card, but I don't recall the details. You could try, I suppose.

    I would have thought the first thing would be networking the machine, if possible, and getting all the data stored somewhere safe without delay.

    I did once try using an IDE to SATA adapter on the motherboard interface
    of a Kinetic but I couldn't get it to work. Of course, this may just have
    been down to that specific adaptor.

    CPC do still have re-certified 3.5" 160G IDE internal Hard drives on their website, available on back-order, expected in stock 06/10/20.

    I have just remembered that that adapter is now in use in my Iyonix to run
    a SATA SSD as the main drive, so it may have been an issue with the MB interface, though I seem to recollect trying it on my ARCIn card without success. One may work on your Unipod.

    The drive is an ADATA SU650 and is reported by "Free" as 112 GB, 40GB
    free. It's the machine I am using for this email.

    Adaptor was from Ebay.

    Yes, as I suggested in my second post, an adapter might well work with the Unipod and it might need the latest version of !HForm.

    If you have a more modern RISC OS machine, ShareFS may well be your
    best bet in terms of speed and reliability. But I abandoned my RPC
    many years ao (except as a monitor stand!), so I can't be sure in
    your case. I did some speed tests with various filing systems some
    months back. ShareFS is an oddity in that it isn't a filing system
    in its own right, it just shares some other underlying filing system
    such as ADFS or RamFS, so the speeds you get depend completely on the underlying FS. I got some pretty impressive speeds with ShareFS
    sharing a RamFS drive.

    I do have an SLU2 NAS I bought some years ago, but I struggled with it,
    and eventually gave up.

    I used an NSLU2 happily for some years until it died. I replaced it
    with a Raspberry Pi 3B+ running OpenMediaVault, which gives me Samba
    and NFS shares, and very creditable transfer speeds of two 2.5" USB
    portable hard drives via gigabit LAN. But again, it's with much
    more modern RISC OS hardware (BBxM, more recently RasPi 3B+) than
    an RPC.

    The important thing is to get everything copied across to somewhere safe.
    Then, if the adaptor idea doesn't work, get one of CPC's re-certified
    drives, put that in and run on it, keeping regular back-ups to a safe
    place.

    I bought a 4TB NAS from R-Comp and Andrew made sure it worked from RISC OS before delivery. !Safestore runs daily to back up my stuff.

    I used an NSLU2 happily for some years until it died. I replaced it

    portable hard drives via gigabit LAN. But again, it's with much
    more modern RISC OS hardware (BBxM, more recently RasPi 3B+) than
    an RPC.

    The 3B+ was close to the performance to my router performing a NAS role
    with a USB3 2.5" HD. Now I've got a couple of Pi 4B's I use one as a
    NAS, as it has over twice the performance of the router, given it also
    has USB 3 and true gigabit Ethernet.

    The router was SMB only, where as the Pi does NFS which is far better
    for Linux (all fs attributes supported for the other Linux Pi's) and
    RISC OS. Although LanmanFS can still achieve a faster transfer with multi-megabytes files, SunFish is far quicker for lots of small file
    transfers. That's important when using it as an application server for
    all my RISC OS machines.

    2.5inch IDE disc connected via an adapter to the motherboard IDE

    Recently I plugged this disc into the adapter incorrectly, only
    connecting the bottom row of pins of the dics to the top row on the
    socket. Since then, even correctly plugged in, it doesn't work.

    in order to make sure the 2.5 inch disc has failed, is there any way
    to connect it to an ARMX6? It's IDE.


    Something similar happened to me many years ago. A damaging short
    circuit was created when the socket and pins were misaligned.

    Thankfully it was the adapter that failed first, not the drive. Take a careful look at the adapter PCB, for any tracks that have melted or
    similar.

    It's a long shot, but worth checking.

    There's almost nothing to the adapter. It connects the 40 pins from the computer side to the first 40 pins on the drive, and connects a second,
    power connector to the other 4 pins on the drive. There are a couple of
    LEDs on the board too, but as it's multilayer, I can't see how that are connected.

    This is how the pins were connected when I mis-plugged it:

    Computer Disc drive
    even nos odd nos
    2 GND 1 /RESET
    4 DD8 3 DD7
    6 DD9 5 DD6

    40 GND 39 /ACTIVE
    42 +5VM 41 +5VL
    44 /TYPE 43 GND

    I can't immediately see how damage could have occurred. The most apparent
    thing is that there is no connection to the ground on the drive. Several
    inputs are grounded, so it might have induced a reverse voltage in those
    as the rest of the drive floated to 5 volts.
