I bought a new Mac Pro and with it a LaCie eSATA card so I could connect a SATA Dock to allow hot-swapping of backup drives,
But, guess what, the drivers aren’t compatible with Snow Leopard despite the pretty product page stating “v10.4.5 or later”.

So, I query LaCie support who manage the the entirely lame

We are aware of compatibility issues with the LaCie eSATA PCI Express Card and Snow Leopard. At this time the latest update available is from 07 Jul 2008 and no current ETA as to when an update will be made available.

And then rather disingenuously suggest rebooting might be required.

All they need now is to suggest turning it off and on again and this bingo card is full.
