Sorry, did not mean to offend. I have never had good luck with Seagate. But I 
don't doubt what you say. My apologies! but my jokes don't always get a 
laugh. :-[ 

If it comes down to that, I may search for a Seagate hard disk or the board 
with the same specs, on your recommendation. I hope it doesn't come to that, 
but I do really need to recover this data.
