Hello All, Ive got a strange issue with 2 dual FW drive enclosures that either erase the drive/carriers i put in them, or damage the drive architecture enough that my computer does not recognize the drive. my computer specs: the computer Im working with in this scenario is a 3 year old mac pro running 10.7.5 so heres the drive enclosures. http://www.advancedaudiorentals.com/products/details/productid/183 In the last few weeks, 5 out of 7 drives I put in come up as unrecognizable,but they will work when I "hard wire" them with a universal adaptor kit I have. OR they become damaged. (As then they won't work with the universal adaptor) and I have to go into recovery mode. So what could have happened recently that both of these enclosures affect these drives in this way. I thought maybe it was a power supply issue with the FW 800 enclosure, I then tried a second unit which is FW400, and had the same results. So... Could 5 drives of different ages die on the same day? Could 5 carries go bad on the same day? Could two different enclosures/"receptacles" go bad on the same day? Or is it something with the Mac Pro FW bus? thanks in advance!!
