Success!  It finished about 4.15am this morning by all accounts
and after a little rest I've started copying DATA2 which is "only"
41MB and should be finished in the next hour.  Then I'll pull off
the rest of the files on this side and give the Domesday Machine
a well-earned rest for the weekend!

Thanks to everyone who helped me get this little idea of mine
out of the starting block!

Best wishes,



Ian

So far so good!  Started at 6.40pm tonight after yesterday's 
effort was abandoned after the MDFS threw a wobbler on me
when I was formatting a new hard disc to use.  It did the format
OK and wrote all the roots and then during the verification it
came up with "Hard drive error on drive F - no BSY" about 20
times even though drive E was the only disc connected and it
corrupted the CMOS RAM, completely ruined one of my floppy discs
and changed its station number to 126!!

Thankfully no permanent damage was done and I have put the
new hard drive in a proper SJ Research expansion box and formatted
and verified it again.

It's been going for 2 hours now although it's only at the stage of
loading the second 8MB chunk.  I suppose loading each chunk is
going to get longer and longer as it has to get to the starting point
in the file each time before reading any data.

This is going to take a lot longer than I estimated, probably about 14
hours so hopefully nothing will melt or explode in that time!!

Best wishes,



Ian

Yes, I think I could have set up a transmit/receive relay somehow,
although I am not sure how much data you get send in each transmit.
I think it's 256 bytes so it would take a long time to send the
data in the buffer to the A5000.

I think the MDFS plan is going to work, I'm just testing the MDFS
version of my "CHUNKFILE" routine with the free space checker.  If
it looks OK I'm going to give the Domesday Machine an hour's rest
and then start it going.   If I can get it going by 7pm it should have
finished copying DATA1 by midnight!!

Best wishes,




Ian

If you wanted to get it direct to the A5000 you could write a pair of apps
to send the file yourself. It shouldn't be too hard (famous last words)
but I'm not how quickly you could do the transfer that way.

Cheers
