My Lacie P3 160GB FireWire drive performs very unreliably - so much so that I cannot trust my data to it. Problems included the dreaded "delayed write failed" message in Windows XP usually followed by corruption. It gets very hot in use which may be part of the problem. I used this drive with a number of PCs including a Toshiba Satellite Pro M10, a HP Laptop and a desktop with a Gigabyte 865PE Chipset motherboard with integrated firewire. Tonight it finally gave up completely and Windows claims it is not even formatted. Lacie UK Tech support are a joke.I also have a Lacie d2 which is much better built, and seems to work well without problems on both USB2 and Firewire. I haven't tried out the new firewire 800 on it yet, so can't comment on that.
