same problems with d2
I have tried mine with both an express card/34 with the 3.0 and the firewire 800, and have experienced a number of sleep disorders, and system freezes that stop as soon as I turn off the d2. I have run the gamut with Lacie with firmware updates and re-formatting, having to move 250+ gb data over to another external. On their recommendation, used cmd line on my PC, ran diskpart, clean, then 8 hours on the MBP zeroing out sectors, all to no avail. My MBP is 2011, i7 8gb blah blah etc. In order to test this issue, I have a homebuild i7 PC with the same blah blah etc, so I have reformattted the d2 to NTFS to see how it handles the sleep issue. If it works there, it will tell me if the problem is the drive or the Mac. I should know within the next couple of days.
The d2 drive works properly on a PC with a fw800 and 3.0 hookup...goes to sleep and wakes up as it should, which tells me it is a "not ready for prime time", i.e. Mac, HD
