    I've bought lots of Lacie drives over the years and have a load of the Black plastic Quadras and the d2 metal Quadras lying about that I want to use.

    My problem is that I seem to have misplaced the corresponding power cables..!

    I can buy the official ones from Lacie here:

    but is there anything special about them that warrants extra cost?

    Can I get any 12v-3A DC charger and it'll do the same job? ie:

    I'm not 100% sure on what matter and doesn't matter on the label. The Lacie P/S says 36W, which it doesn't on the amazon link.

    Thanks very much!

    The only problem with buying the generic power supplies is that the barrel connector may be a different size...

    BTW, since the amazon link says it's 12V, 3A, then if you do your math, it comes to 36W also.

    Ah, that makes sense. W=V*A rings a bell!

    How do I tell what size the barrel connector will be - is there a 'standard' or anything?

    how old are the drives? i called lacie once and even though one of my drives was out of warranty, they shipped me a new power supply.

    There probably is a standard, but I'm unaware of it :)

    Standard issue by whom?

    Seriously, the extra cost for a name brand LaCie power supply is very little compared to the original cost of the drives and enclosures.

    There are vendors beside LaCie that sell the power supplies, and at a discount. Its been over a year since I was shopping but, at the time, the discounted price was along the lines of other supplies with unknown compatibility.
