    Hard drives not mounting
    So my PowerMac is failing to recognize hard drives consistently. It will recognize some of the drives some of the time, some drives all of the time, one drive it will NEVER recognize, and a pair of drives it will NEVER recognize at the same time.

    I have been able to recognize most of the other drives on other Macs without any trouble. One drive now appears to be dead to all machines. Wondering if my Mac killed this drive (it was brand new!)

    Anyone got any idea what is going on here?

    Here are the pertinent details:

    OS X
    2 x 3 Ghz Quad-Core Intel Xeon
    9 GB 667 Mhx DDR FB-Dimm

    Dead drive - GRaid 3 TB
    Occasionally Reconizable drives (but never together) - Verbetium 1 TB drive
    Always Reconizable drive (2nd) RRaid 3 TB.

    Many Thanks.

    Are these external drives? How are they connected? How are they formatted? If external, are they bus-powered or require a power source? If external, have you tried an alternate port to plug into?

    Please verify and include the exact model/year of your Mac and OS X version number (available from "About This Mac", then "More Info" on the Apple menu).

    Have you tried rebooting. Every now and then my Mybook will not mount, a simple reboot fixes that.
