    Exclamation USB mass media wont mount

    Question is; now how do I use this drive? or just toss it?
    Situation is this:

    USB external mass media device;
    Apple PC w/ 10.5 os
    ATA drive in usb2 case
    set ata to cable select - connect to Apple PC - turn on usb - device mounts
    reformat to FAT, copy files to it. check files, all seems well
    .
    Unmount and disconnect.

    Next day, reconnect to add files & device will not mount.
    Look in Disk Utility, device is not shown
    Look in System Profiler, device is shown, but not hard drive

    reset ata to “master” & slave & then to “force device 1 present” neither will result in hd mounting.

    move to MSDOS PC, win7 os,
    device manager shows drive, see as “not initialized”
    attempts to initialize Fail.
    HD will not mount.
    attempts to access Properties fail.

    Thumb drive formatted FAT mounts in seconds, in both PCs, same connection.
    installed new ata cable from drive to usb card, & tried a different usb cable too.

    both PCs see the external device usb driver and hardware in the box, but not the hd it self, .....

    My first thought is if the HD should not be formatted.... FAT on the other hand it should work. You have a hard drive... formatted FAT with OSX 10.5 on it? But won'y boot or mount.

    There are mods and members who cross platform a lot and should have helpful input. I just have my Mac and Google.

    Sounds like a simple hardware issue. It either works every time or it isn't any good. Whether it is the bridge or the drive? Who knows. However, you could test the drive in a internal configuration - even attached to the G5s optical drive bus.

    Default right u r

    this is NOT an internal drive, but an External ata in a usb box
    intention was to put in on the MSDOS pc as a backup, thus the fat ;;;


    rechecked with another usb connector, same no mount.

    in Profiler the usb hardware shows up, but no drive

    like you say, there is one last test, put it back in an old machine with ata connection and see do it work.

    I was hoping it was something simple like the jumpers,

    I have a few in from years gone by builds, they are small and cheap, but why waste them if still usable?

    I got it that it was an external drive. However, all that means is that there is an internal ATA drive installed inside of a USB enclosure. Take the drive out and test it inside something that has an ATA connection - like a G5 where the optical drive goes, or a PC with an ATA connection. A drive is a drive is a drive.

    The point is only that there is no way to know whether the problem is the USB bridge, the power supply or the drive itself. Take the drive out, install inside a computer, and you are only testing the drive itself.
