    Haalpp! G4 & Ext HDD prob
    AGP Mac G4 running OS 10.3.9

    Bought an external 250GB HDD about 2 years ago which has worked
    perfectly until now.

    If I switch on the external HDD before startup, the opening menu gets as far
    as 'Loading external drives' and hangs till I switch off the external
    HDD. when it completes the startup no problem.

    The telltale on the front of the external HDD flickers as it should.
    Trouble is, its a 250gb so, even tho it would fit inside my G4 its too
    big to open (I believe it will only read 128GB?) Is this correct?

    If I boot up the Mac and *then* switch on the HDD and try Disk Utility
    it also hangs until I switch off the ext HDD.

    If I plug it into my PC laptop, it 'sees' the drive in 'Manage' but
    won't open or amend the drive letter it. Nor will it display in 'My Computer'.

    Will Diskwarrior sort this problem? I did try it and it, too, hung up
    while waiting for drives.

    I really need access to this drive cos its got all my family pics and my
    Resume on it!

    Anyone got a simple solution before I take it to a specialist?

    How did you format the eternal drive and yes 128GB maximum an AGP will recognise without a PCI controller card? To make an external bootable using Superduper or similar reuirs formatting in Apple Partition Map.

    Thanks for the reply!

    I didn't have to format the HDD - just plug and play.

    I can't access the external HDD at all.

    :-(

    If I can get access, will formatting the HDD clean off all the stuff I've got in there?
