I see there were a lot of Views, but no Replies....but I thought I would share the outcome with you.
Using Vista partition I could see and use my I-Tunes library on D Drive but no documents.
Using Win7 partition I could see/use my Documents on D Drive but not my I-tunes library.
Yesterday ( and I dont know why) I decided to put SP2 on my Vista partition. Seemless....painless.
AND NOW - SOMEHOW and FOR WHATEVER REASON - from both Vista or Win7 O/S - I can use and edit and see all my Documents and all my I-Tunes library on my separate D Drive.
I am a happy (though non-plussed) camper.
One (other) oddity though. MY COMPUTER shows my C Drive as 500GB when it is in fact now 400GB (100 GB re=partitioned to W Drive for Win 7 & THAT 100GB shows up properly)...
