I'll outline them below. 1) Because I have a fair number of old drives from a set of RCPs. Not all of them available at the same time. I don't to either have to keep opening up my computers or leave them open, and I don't want to keep on changing things inside them. 2) When I've finished I plan to use the adaptor for various other purposes. Say more about that below. I have now bought a USB-IDE adaptor from CJEMicros. As step 1 I've decided to use this to read the contents of the old IDE ADFS discs using my Iyonix. At first this would not work. However investigation by myself and CJE showed that the disc *must* be set to 'master' - otherwise the adaptor would not even register its existence as a USB device. I also have updated my Iyonix with the USB software upgrade. This means that at present I am doing as follows. I attach an old IDE ADFS disc to the CJE adaptor and also a USB harddrive formatted fat32. I then copy across the contents. The aim here is to have all the old disc contents on a new larger USB drive I can then use to keep and carry the contents. The new drive is then accessible with my Linux boxes as well as my Iyonix. The trade-off here is that being fat32 I can use it with both Linux and RO. But there are obviously changes due to the differences between fat32 and ADFS. I'm also transferring some items where I think that may matter to an ADFS disc. When the above process is done I plan to fit a reasonably large ADFS formatted IDE disc 'permanently' into the adaptor (which is actually a case) and use it to hold backups, etc, from the two Iyonix machines we use. But the whole process will take weeks to months as am just dealing with the old RPCs one or two at a time. This raises two questions in my mind. Firstly, has anyone already done an 'automated' way to reach such files on a fat32 (or ext3) disc and copy them with the ,XXX filetype extension used for hostfs? I can see on the fat32 discs that files still have types when seen by my Iyonix (using fat32fs) but I don't know how that is stored on a fat32 disc. Secondly, is there a way to get RPCEmu to detect and access a removable AFS formatted HD I plug in via USB in the same way as it sees an image file inside the PRCEmu directory? That would make access much easier for large amounts of data and make moving between the machines easier.
