I am trying to transfer the contents of my RISC PC 600 hard drive, running RISC OS 3.5 to the Pi SD. The idea was to remove the hard drive from the RISC PC, plug it into a USB TO IDE adaptor connected to the ras pi and copy the files. I found one post that suggested this works.
I have tried everything I can think of, but failed. The Ras Pi boots into RISC OS, but then seems to hang when looking for the drive.
The hard drive is powered from an old PC PSU.
Initially I tried connecting an old Windows PC drive via the IDE to USB adaptor to the Ras Pi. On booting into RISC OS, the drive was recognised and I formatted the drive. The drive appeared on the desktop, and I copied files into it from :0, got error message about too many files in directory, I think, but not bothered as I suspected it was because I selected old format, when I formatted the drive. Copying seemed to work so I was not bothered.
so now I had a working system!
These are some other things I did:
I suspected that the boot sequence was running from the RISC PC drive ... It's an Acorn / Xemplar Classworks system that's designed to protect the hard drive from children deleting things. So you cannot get at the root !boot unless you have the password (long forgotten). I have disabled this and I renamed !Boot and did *OPT 4,0 to stop the drive booting. I have verified the drive on the original machine.
I tried to see if the old windows drive formatted on the Ras Pi could be read by my RISC PC. This failed as it was a 2GB drive and RISC OS 3.5 only supports up to 512 Mb. I tried to format this drive to a smaller size, but !HForm could not get info it needed fron the drive.
Could it be an incompatible USB to IDE adaptor? Does anyone know on ones that work. Or am I just expecting too much!
