Yeah. I've now copied the entire MDFS onto another HD (tho thats of equal
age!) and at some point I'll copy everything onto my RiscPC as well. It
seemes the drive just needed to 'warm up', but how much longer it'll live
if of course anyone's guess.

I could generate a text file with the load/exec addresses in it for each
file if that's any use, if not I'll try and get an SSD made of it, tho
that might take a few days, as I'll need to drag a beeb out to do it with!

*PUTGET is an SJ thing to block together single byte read/write calls into
one chunk - a cache in effect. Because of the Econet overheads in writing
a single byte at a time, it made BGET/BPUT quicker as it would get (or
put) a load of bytes at once. ACCEL also did something similar, and I
think the Master had it built into the OS.

I'm not sure if CAVE requires it, but it was there on the version I got,
so I guess someone thought it necessary.

Cheers
