First time posting, also a Mac newbie (recent windows convert) so I'm hoping I can get some help here :)

I have a Hitachi Deskstar drive in an external casing that I got from ebuyer. (its one of those unknown fairly cheapish enclosures) connected via firewire.

I hook it up and it works fine, but then at some point over the next week or so I'll realise that my last update was 3 days ago or so.

At this point the Mac will not recognise the drive as existing and the only thing to do is switch off and on the external enclosure.

It then works fine for a while.

If I had to guess I'm assuming its powering down or something when the Mac goes into standby? Is there anyway to solve this?
