Strange FW HD issue..

[guy mcdude]

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.

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!!

I'd try a different enclosure.

Sounds more like "an enclosure problem" or incompatibility with the Mac Pro, rather than "a problem with the drive(s)" ....
