From: "Jules Richardson" <julesrichardsonuk(a)yahoo.co.uk> Hi all, I'm just wondering how to back up the hard drive (a 20MB MFM) in my Research Machines fileserver. The system runs CP/M, has a couple of floppy drives, and the hard disk is hooked up to a Xebec controller with a SASI bus linking it to the host controller in the fileserver. There are actually two problems: 1) Getting the data off the hard drive somehow (possibly via floppy) and being able to read it on another system (ideally a PC I suppose)

2) Being able to rebuild the system if/when the hard drive fails.

Thoughts on both are welcome! I don't have any kind of OS source media for the system, and it wouldn't surprise me if it isn't the only survivor :-( Maybe there are utilities on the system itself to recreate bootable OS media, but my knowledge of CP/M is a little lacking! For my old SCSI systems I tend to hold a raw block-by-block backup image of the drive by putting the hard disk in a PC with Linux and dragging data off that way. If the drive fails and I can't get an identical replacement, a slightly larger drive still works with a little bit of wastage. Due to the relationship between the controller and drive using ST506 I gather things are probably a little more complex though... cheers Jules ===== Backward conditioning: putting saliva in a dog's mouth in an attempt to make a
