#7 takedata.js needs error checking if toArray() fails

[rawnc]

ran this script on several machines in our office and
on several of them it bombed around line 182 on this
script - when trying to determine the harddisks. This
happened on our lowend new Compaq machines and some of
our more complex ones, like onces with RAID
controllers. I think the line that is dying is
caparray=VBArray(d.Capabilities).toArray();
