Hello Tony,
Really sad to see that one bad move or actually "no move no reply" from a company can destroy a 12 year relationship.
Nevertheless I think you are right as so far as I can see they still did not reply about the wrong sized harddisk.
While the only thing they should do is replace these harddisks!

Anyway I saw you are from Malta!
The first time I saw a WK4 in action was on Malta, which must have been around 1998 while I took a small holliday with my family.
I wonder If you know the guy using the wk4 (Malta is small so I am pretty sure you must know him) and If you have his mailadress.
I lost his mailadress with a crash on my system a couple of years ago.
His name was David Xuereb.

Thanks for letting me know,

Fred
