eSATA external HDD ok under XP, no longer activated under Vista x64

I have seen a thread about that, but since it's getting old, I wanted to
post a new one to ensure it will be seen... Sorry for redundency if you
have read it elsewhere.

I have a dual-boot PC (Win XP Pro 32 bit and VISTA x64). The Nextar3
plugged through eSATA (ASUS P5B) was seen until a few days ago when I
updated BIOS (for another problem).

Since then, only XP sees the external drive (in a Nextar 3 encavure).
Under Disk Management, I can see this ''disk 0'' (dynamic) as
unactivated (in Vista) - I don't even see the two volumes on it anymore.
(And the drive had been plugged there way after my Vista installation).

Under XP, I have no problem at all...

I have been trying to find a fix to that at Microsoft forums, and a few
others as well, but the only reply was to convert to basix disk - which
would then require to wipe out a few installations that I use only under
XP...

And Microsoft knowledged base suggest to ''reactivate'' disk with a
simple right-click, but I don't even see that option possible (it's not
there, not even in grey !)...

Anyone finally found a fix to that ?

Thanks,
Rob
