I have a Risc PC which has been unused for ... a few years (for reasons I won't bore you with). I finally managed to get round to inspecting the insides and found that - as might be expected - the battery of death was looking a bit fusty.

At minimum I basically just want to salvage data from the hard disc. What would be the best way of going about that?
I have/had a lot of photos in an image filing system of some description, but I don't remember exactly what - IIRC it stored them in subdirectories with random names, which whould be fine - presumably they'll have EXIF data inside so in theory I could even sort them back into chronological order again. If they're in the one big file approach that will obviously be much harder to retrieve.

I'm tempted to see if it switches on so I can try transferring data via USB flash drives - which would be fine, if it works just once (for enough time).

I guess I could try to buy a replacement motherboard - haven't looked into that yet. If that would be very expensive then I guess it's a bit of a waste.

Advice greatly appreciated.

I've done this lots of times before.

If you send the RiscPC to me I can copy all the data off your hard drive onto CDs or DVDs in zip files. This you can then transfer to any other system, plus you'll have a (nearly) permanent archive of the data.

Also I can have a look at your motherboard. Sometimes the damage is beyond repair, but not always. Won't know until I see it.

A simple (ish) way, if you have IDE (rather than SCSI discs) on you RPC. You'll need a IDE/USB HD adapter/enclosure and a linux box.

Put the drive in USB/IDE thing, plug into the linux box and use 'dd' to copy the raw disc image to a file. You can then use that file in Red Squirrel, Virtual Acorn or RPCEmu and use it either in that, or copy the files off using 'hostfs'.

I can give a lot more info on this route if you want to follow it.

A Raspberry Pi, RISC OS SD card and a USB IDE adaptor would be another option. (Biggest problem would be getting the Pi.)

The only parts of the RiscPC that are normally affected by a leaking battery are CMOS Settings and sound. So if you do a POWER ON Delete and then a shutdown restart you should be back to normal usage!

Transferring the data off is another matter.
If you have a network card then there are free or paid for utilities.

Using a parallel port is another method of transferring files http://www.serial-networking.fsnet.co.uk/zerilink.htm

Your forgetting this is a religiously RISC OS only forum :P

I've spoken to a few people who snort at the use of linux, or any other operating system for that fact. Don't get me wrong, I'm all for RISC OS, it's just not to the point it's cutting my nose off to spite my face. Use the best tool for the job, not pliers to unscrew a screw. Unless you haven't got the right screwdriver of course :D

Why did you even bother to bring that up? I'm sure the OP doesn't really care as long as there is a way/ways to get at his precious data/files.

The OP was given the definitive (and probably, for him, simplest) answer right at the start. Then, as so often happens, it all got messy.

Paying you isn't always the only answer Dave.

Well said. Different approaches have different benefits and downsides. Whole-drive imaging (dd in Linux, for example) gives a better backup than any transfer can, especially if drive lifespan is limited.

Transferring the data off is another matter.
If you have a network card then there are free or paid for utilities.
If the OP can get the machine working, even once, and has a NIC and functional TCP/IP stack installed, FTP is also a pretty reasonable alternative.

The benefit is that both of these can be done at minimum (or zero) cost, at home, and more or less instantly. The OP has been on this site for the last decade and we know he's not afraid to get a little technical, so perhaps he's entirely willing to try things for himself. It does no harm to give options and alternatives.

Thank you everyone for all your advice - I do appreciate it.

I'm a bit rusty on my RISC OS stuff, and always was nervous about fiddling with the hardware.

If the machine does boot up with the reset trick, and it can talk to everything then I hope to be able to transfer stuff off myself - it's just a case of getting round to it. The machine isn't networked but it does have USB, and I have a couple of fairly small USB flash disks. It'll need some time for a few transfers; hopefully I'll be able to try that in a couple of weeks.

I've used Linux at work, but don't have such a machine at home. It's very nice to learn that Linux has the ability to read RISC OS format hard disks. I was thinking about getting a raspberry PI, so the combination of these might be just the push I need to actually get on with that.

If it's beyond that then I totally will send the hard disk to Dave.

I'll report back on what happens - but it'll probably be a while.
