eSATA Blu-Ray writer - how to?

[bitbuerster]

Hi all,

I'm running Windows Vista as host and XP as guest system. Recently, I got myself an external Blu-Ray writer, a Buffalo BR-816SU2 (actually, Vista tells me it is a "Matshita BD-MLT SW-5584 ATA Device"). Connector type is eSATA.
The drive itself is recognized immediately from Vista and works like a charm there. However, VirtualBox doesn't see it at all; I may run the accompanying driver CD and although it doesn't complain, it doesn't mount the drive: Not as a drive letter, not showing it in the device manager or the compmg.msc or somewhere else -it is as if the device doesn't physically exist at all.

As a matter of fact, in VirtualBox' hard disk settings, I ticked the "activate SATA controller" checkbox, but the list of drives just shows my C: image with my XP hosting harddisk file. Seems I'm missing a very basic point here: Where the hell can I mount an external SATA device?

Thanks for your hints...
