Hmm. That's strange. I have not had any issues with LaCie drives in any version of Mac OS X, including Leopard. I guess I'm one of the lucky ones.
Could be.
I know a lot of the issues get resolved with firmware updates. But, the problem with a drive that requires a firmware update, is that you can only get updates as long as the manufacturer supports that drive and offers updates.
I prefer the Oxford chipset because I've never heard of one requiring an update to continue working, and because everyone I've spoken with during these changes and updates to OS X has reported no problems if they've had an Oxford 911 chipset.
On the other hand, a lot of people usually start complaining around update time when they have either generic drives, or drives from companies that use lesser chipsets.
I'm glad you've had good success with yours.
I just try and head-off questionable issues by going with the most solid chipset I can.
I had a guy who was a higher-up at Lacie jump into a previous discussion, and he claimed that it was only because of the large number of drives they've sold that you find so many complaints.
But, I know there has been an equally large or larger number of drives shipped with the Oxford chipset (since they are used in a lot of drives), and to have never had the kind of complaining from Oxford 911 chipset users that I hear from Lacie owners, that says something to me.
Sure, it's possible that any drive could stop working due to some change in OS X. But, it just seems that the Oxford 911 is somehow durable and survives without issue.
